AMERICAN MICRO-LEPIDOPTERA.

BY BRACKE.YRIDGE CLEMENS, M. D.

Tineina.

STROBISIA Clemens.

Proc. Acad. Nat. Sci. May 1860, p. 164.

S. levipedella. — Fore Avings dark broAvnish, Avith a cupreous hue. The apical half of the Aving is darker than the basal half. About the middle of the costa is a short, oblique Avhite streak and another of the same hue midAA’'ay betAAmen it and the tip of the AAung, perpendicular to the costa and of nearly triangular form. Beneath the first costal streak are tAAm short, longitudinal dashes, one on each side of the fold of the AAdng, and tAvo others of the same hue, parallel, and beneath the second costal streak. Cilia Avith a violet irridescence. Hind Avings dark broAvnish.

Antennse dark broAvnish. Head AAdiitish beneath. Labial palpi Avhite, third joint dark broAAmish exteriorly. Feet annulated Avith Avhite.

When it alights after a flight, it walks in a wavy line and turns romul several times in a circle.

I have a single specimen, taken on wing the 1st of June.

PARECTOPA Clemens.

Proc. Acad. Nat. Sci. June 1860, p. 209.

P. Robiniella. — Fore Avings fine broAvn, someAvhat golden, shaded Avith dark broAAUi. Along the costa are three oblique silvery streaks, the one nearest the base of the AAung, short, and the otliers extended to the middle of the Aving, each sha¬ ded along their margins AA'ith dark broAAUi. On the inner margin are three sil¬ very dorsal spots, placed opposite the spaces betAAmen the costal streaks. Near the tip of the A’ring is a transverse, narrow, curved silvery line, passing from the costa to the inner angle. At the base of the cilia are tAvo black converging lines, AAdiich do not meet opposite the apex of the Aving. Cilia silvery Avhite, tipped Avith dark fuscous. Hind Avings dark broAAUi, cilia the same.

Antenm® dark broAAui, very slightly annulated AAuth AAdiitish and the extreme tip silvery-AAdiite. Head dark broAvn. tuft and face silvery-AAdiite. Labial palpi dark fuscous, the third joint sihmry-AA'hite. Feet annulated AAuth AV'hite.

The larva mines the leaf of the locust, making a blotch mine, on the upper surface of the leaf, with a number of lateral galleries running out from it, on each side. Its habits in all respects are similar to those of F. lespedezsefoliella. I am unable to indicate exactly the month in Avhich it should be sought, as I have mislaid the notes made on this spe¬ cies; but I think it can be found in the latter part of spring. I have ahvays found the mines untenanted at the time the leaf is mined by Lithocollefis Rolnniella.

18G3.]

In the Fifth Annual Report of New York State Agricultural Society, Dr. Fitch describes two locust leaf-miners. The first Anacampsis Ro- hiniella^ is unquestionably a Litliocolletis. If Dr. Fitch has been lead into no error it is a new species, and the specific name must be changed. The other species, Ar<jyvoinige& Pseud acaciella^ is identical with Lith- ocolletis Rohiniella Proc. Ac. Nat. Sci. Nov. 1859, p. 319, first descri¬ bed by myself a year or two previously in the Entomologist published in London, by W. H. Stainton. P. Rohinella and L. Rohinella the only miners I have found in the leaf of the locust, although I have examined the leaves yearly for several years in succession. And I will candidly say, that I do not think there can be two species of Litliocolletis^ that mine the leaves of the Locust, for Dr. Fitch’s history of Anacampsis Rohiniella is contradictory and at variance with the natural history of the genus. His description of larva shows, that it belongs to the second larval group (see Proc. Ac. Nat. Sci. Nov. 1859 p. 318) the mines of which are invariably and situated on the up¬ per surface of the leaf; but according to his description the mine is on the under surface and tent like. The flattened Lithocolletis larvae can¬ not make a mine similar to that of the cylindrical larvae, in consequence of the different formation of their heads. In all probability Dr. Fitch has been lead into error respecting the insect he has named Anacanip- sis Rohiniella.^ and I am unable to recognize in his description of the imago, any of the species of Lithocolletis known to me.

BRENTHIA Clemens.

Proc. Ac. Nat. Sci. May 1860, p. 172.

The second joint of the labial palpi almost tufted.

B. inflatella. — Fore wings dull orange; in the middle of the wing dark fus¬ cous, dusted with white. At the base of the wing are three or four small spots of a beautiful metallic green, and two others of the same hue, on the disk, be¬ tween which, on the costa, is a small white spot. At the apical third of the wing is a curved metallic green hand, extending from the costa to the inner angle, beginning on the costa in a small white spot. A little beyond the met¬ allic line, towards the base of the wing, on the inner margin, is a small spot of the same metallic hue. Near the hinder margin is a subterminal dark fuscous line, which from the costa to the middle of the wing is overlaid with metallic green scales, and on the costa between the two transverse lines, is a white spot. Cilia fuscous, white in the middle of the wing. Hind wings dull fuscous, with two irridescent spots near the inner angle. Abdomen with two irridescent spots near the tip.

Antennae fuscous, annulated with white. Head and labial palpi grey varied with fuscous. Feet dark fuscous annulated with white.

I have before me a single specimen taken on the wing in July.

COLEOPHORA Zeller.

Proc. Acad, ISTat. Sci. Jan. 1860, p, 4.

Wings with long cilia. Hind wings very narrow, lanceolate. The subcostal vein is attenuated towards the base of the wing and near the middle of the wing divides into two branches. The median vein runs near the inner margin of the wing and divides into two short branches. The discoidal vein, often indistinct, is simple and free.

The fore wings are lanceolate, often nearly caudulate. The discoi¬ dal cell is closed, long and narrow. The subcostal vein is rather re¬ mote from the costa and throws off from the cell three branches to the exterior margin, and two to the tip of the wing from the exterior end of the cell, sometimes a furcate branch. The median vien gives off two very short branches from its extreme end to the inner margin be¬ hind the tip. The submedian has a long fork at its base.

Head above and in front smooth. No ocelli. Antennse sometimes thickened ivitli scales to the middle^ generally slender, simple, basal joint elongated, frequently with a tuft of hair. Labial palpi slender, rather porrected, with a slender prolonged tuft from the second joint, the third joint pointed. Tongue scaled, about as long as the anterior coxse or a little longer.

The larva is a case bearer, changing to a pupa within the case.

Antennal stalk simple., basal joint tufted.

C. leucochrysella. — Fore wings immaculate white, slightly tinted with yel¬ lowish at the extreme apex. Cilia yellowish-white. Hind wings dark fuscous, cilia the same. Antennse annulated with black and white. Head and labial palpi white. Feet annulated with white and brownish.

Taken on wing in the latter part of J uly.

Antennal stalk simple, basal joint not tufted.

C. concolorella. — The entire insect is of a uniform, rather dark yellow-ochre- ous color.

Taken on wing, 13th of June. A single specimen.

I have other species belonging to this genus, but as they are not in perfect condition, I forbear to describe them.

MARMARA new gen.

Hind wings setiform. The subcostal vein is faint, attenuated and simple. The discal vein, free, central and two-branched. The median vein simple.

Fore wings narrowly lanceolate. The disk long, narrow and closed. The subcostal vein is well defined from the base to the first marginal

branch which appears to be a continuation of it. But from the origin of the first marginal branch, the vein is greatly attenuated and is de¬ flected towards the middle of the wing, and subdivides into two branches opposite the point at which the first marginal branch attains the costa. The two branches into which the subcostal divides are delivered one to the costa just behind the tip and the other midway between this and the costal end of the first marginal branch. The median vein is two- branched and is well defined from the base to its branches, all of which are attenuated. The posterior branch is short, and the next is deliv¬ ered to the tip of the wing and receive an oblique discal vein from the last branch of the subcostal, which closes the disk. The submedian vein is simple.

Head smooth, with oppressed scales. Ocelli — ? Antennae one-third less long than the fore wings. Labial palpi slender, ascending, not higher than the vertex; the second joint is scaly, the third smooth. Beneath the labial palpi are small, ascending maxillary palpi. Tongue naked, as long as the fore coxa and femora.

The larva is much flattened, and the segments separated by deep in¬ cisions particularly on the sides. The head is extremely thin, circular, with a peculiar appendage in front of the mandibles, similar to that found in the larva of Lithocolletis of the second group^ which it like¬ wise resembles in form. Like these it has three feet and three abdom¬ inal prolegs and one terminal pair, all very short. It leaves its mine at maturity to weave a white, semi-transparent cocoon within some cre¬ vice of the bark of the tree on which it feeds or upon the ground. The exterior of the cocoon is covered with little froth-like globules, which resemble minute pearls.

The imago rests with the front part of the body elevated, and I be¬ lieve, the fore feet applied to the breast, like the members of the ge¬ nus Tischeria. The antennae are held extended at the side of the head, and have a constant trembling motion.

M. salictella. — Fore wings dark fuscous, with a silvery-white band at the basal third of the wing, and a slightly oblique one of the same hue, in the mid¬ dle, inclined towards the inner angle. ITear the tip of the wing is a dorsal and costal silvery-white spot opposite each other. Behind the dorsal spot, is a nar¬ row, somewhat curved white streak, extending from the apical cilia to the mid¬ dle of the wing. Cilia silvery-grayish at the tips. Hind wings grayish-fuscous.

Antennae grayish-fuscous. Head silvery-white. Labial palpi silvery; the hairs of the second joint touched with fuscous. Maxillary palpi dark fuscous.

The larva mines the young branches of the yellow willow tree. I

8

[March

have always found it in those that spring from the trunk. Its mine is extremely long and very narrow, being only a tract beneath the young and delicate cuticle of the branches^ sufficiently wide to accommodate the body of the miner. At first it is difficult to detect the mine, but after some months it is easily traced by the elevated line of reddish- brown matter that marks the coarse of it. Thus it is easily found in early spring before the buds have expanded, and the larva may be sought in April and is easily reared, In the spring the larva is of a dark lemon-yellow color without markings, and at this time the larva can be seen through cuticle of the branch. About the middle of May or rather about the 10th of the month, the larva will be found banded alternately with red and yellow, with two black dorsal dashes on the second segment. (I regard the. head as the first.) This is the indication that it has reached its maturity and in a day or two it cuts the cuticle and leaves the mine to weave its cocoon, sometimes in the angle of a bud on the branch of which it has been feeding, and sometimes on ad¬ jacent substances.

In rearing this insect, it is simply necessary to thrust the branches of the willow into wet sand contained in some convenient vessel and to protect them so that the larvae cannot wander after leaving their mines.

The perfect insect appears after a pupation of about a month, or as in the case of one specimen specially observed in 26 days. It may be found as an imago, therefore, about the middle of June.

GLYPHIPTERYX, Hiibner.

Wings oblong or elongate, with moderate long cilia. Hind wings rather ovate or lanceolate. The costal vein is conspicuous, free and simple. The subcostal simple, attenuated towards the base. The dis- cal vein gives rise to two discal nervules. The median subdivides in¬ to three branches, the upper two arising from a common base.

In the anterior wings the secondary cell is distinct and the subcostal vein subdivides into four branches, the first arising behind the second¬ ary cell and three from its hinder end, the last of which is delivered to the tip of the wing. Beneath these are three nervules thrown olf from the middle of the disk. The median is 8-bran died, giving ofi' the nervules somewhat aggregated.

Head smooth. Forehead broad. Ocelli large. Antennm slender, short, not one-half as long as the fore wings, with distinct joints. Lab-

ial palpi arched, reaching about the middle of the front, (but in the dried specimen decumbent or porrected) cylindrical, slightly hirsute; terminal joint pointed, as long as the second. Tongue naked, of mod¬ erate length.

G. impigritella. — Fore wings dark bronzy-brown, with a conspicuous, curved silvery-white streak, arising from the basal third of the inner margin, where it is widest and curving to the middle of the wing and dark margined on both sides, On the costa are five short, silvery-white streaks, the first oblique, the others nearly perpendicular, all of which are black margined internally, the lines which form these margins are more or less distinctly extended across the wing. That of the first and second costal streaks meet just above the end of the con¬ spicuous dorsal streak from the inner margin. Between the costal streaks, the wing is slightly touched with golden-brown. Opposite the first and second cos¬ tal streaks, is a small white spot on the inner margin, the curved black margi¬ nal line of the second costal streak touching its inner side. At the tip of the wing is a conspicuous round black spot, and beneath it, in the cilia, is a silvery gray hook, and the cilia of the extreme tip is slightly touched with a silvery hue. Hind wings and cilia of the same hue as the fore wings.

Antennae and head dark bronzy-brown. Labial palpi whitish, with fuscous exteriorly. Feet annulated with white.

Taken on wing in July.

This insect is very like Q. eqidtella of Europe. The darker color of our species, the dark margined silvery streaks and the absence of silvery-violet spots, are the chief differences. The European species burrows in the shoots of Sechim acre (Stone-croper Wild Orpine) and probably our species may be found in the same plant or another of the genus Sedum.

GRACILARIA Zeller.

Proc. Acad. Hat. Sci. Jan. 1860, p. 6.

Wings with long cilia. Hind wings narrowly lanceolate; the costa is concave or excised in the middle. The costal vein is short, entering the costa at the beginning of the concavity. The subcostal vein is simple and runs near the costa, and is much attenuated posteriorly. The discal vein runs through the middle of the unclosed cell, arises at the hase of the icing much attenuated^ and is connected l>y an inoscida- ting^ minute hranch with the subcostal vein about the middle of the wing, and becomes furcate at its extremity. The median vein is plac¬ ed near the inner margin and is three-branched.

Fore wings lanceolate. The discal cell is long and narrow and the subcostal vein is attenuated towards the base, and gives off a single, rather long, marginal branch, quite near the base of the wing. From

10

[March

the hinder portion of the discal cell nine nervules are given off, four of which go to the costa, and five to the hinder margin. The snh- median vein is simple.

Head and face smooth. Without ocelli. Antennas filiform, as long as the fore wings. Labial palpi slender, ascending, cylindrical; the second joint with appressed scales, not tufted; the terminal joint point¬ ed. Maxillary palpi rather long, filiform. Tongue clothed with scales.

In the small species of this genus, the maxillary palpi are less devel¬ oped, and the labial palpi are almost drooping. In the dried specimen the labial palpi are almost always more or less drooping.

The species of this genus are elegant in form and often gaily color¬ ed or prettily mottled. The position of the imago at rest is extremely characteristic, but not peculiar to it. The front of the body is eleva¬ ted by the fore legs being held vertically, so that the tips of the wings touch the surface on which the insect rests. The imago appears to be about to poise itself on its wing-tips, or to have raised its head into a po¬ sition of profound attention. The larvae have only fourteen feet; when young they mine the leaves, but at a later period of growth many of the species constrnct cones, by rolling up a portion of the leaf. They devour the inner portion of the cone, which thus becomes discolored and easily observed.

The description of the species below was made originally from a poor specimen, and I therefore take this opportunity to amend it from a per¬ fect specimen which I mistook at first for a distinct species.

G. venustella. — Proc. Ac. ISTat. Sci. Jan. 1860, p. 6. Fore wings dark fuscous, Avith four equi-distant costal streaks, the first, near the base of the wing, quite short; the second extended obliquely across, or nearly across, the wing and con¬ stricted or partially interrupted near the middle; the third l^ewise oblique, but narrower than the second, extended to the middle of the wing; the fourth, near the tip of the Aving, slender, curved, nearly vertical to the costa and all dark-margined internally. The basal portion of the inner margin is Avhite. Cilia dark fuscous, at the tip of the wings white, touched with black at their ends, and having a few black-tipped scales in the middle of the Avhite spot. Hind wings dark fuscous, cilia the same.

Antennse fuscous. Head and face white. Labial palpi white, the 2nd joint fuscous at its end and the third with a broad fuscous ring, leaving the extreme tip white.

Taken on wing the 25th of July.

GELECHIA Zeller.

Hind wings trapezoidal.^ slightly or deeply emarginate helow the apex.

The costal vein is simple; often there is a narrow intercostal cell be¬ tween the costal and subcostal veins at the base of the wing. Most frequently the subcostal vein is bifid about its apical third, rarely the subcostal vein is simple. The median vein is 3-branched and nearly always the two upper or superior branches arise from a common stalk, or from one point. The discal cell is sometimes closed, when it gives rise to a single nervule; sometimes unclosed, when there is a single free discal nervule or none. When the subcostal vein is simple, there are two discal nervides.

Fore wings oblong or elongate, pointed or obscurely pointed. The apical nervule of the subcostal vein is usually furcate and terminates in the costa before the apex and below it are five veins from the pos¬ terior end of the discal cell. Sometimes the apical vein is trifid.

Head smooth. With or without ocelli. Antennae with joints thick¬ ly set. Labial palpi moderately long, or long, refiexed; the second joint beneath slightly broader than the basal joint, with appressed scales, hardly resembling a brush, sometimes quite smooth; the termi¬ nal joint slender, almost needle-like, smooth and pointed. Maxillary palpi very short. Tongue of moderate length, clothed with scales.

This genus is of great extent and comprises a considerable diversity of species. The imago is extremely active.

The habits of the larva3 are extremely varied, feeding upon leaves fiower-buds, young shoots, in the interior of grains and seeds. The species that feed in buds and shoots are mostly in the larva-state in spring and the beginning of summer; those that feed in and upon leaves are met with in summer and autumn and those that feed on seeds do so in the autumn and winter.

Gr. nigratomella. — Fore v/ings shining white. The ai^ieal portion of the wing is pale brown and contains an oblique white streak margined internally, on the costa, with dark brown. Beneath the tip is a small black spot, towards which the oblique white streak is directed. Along the costa, between the tip and the costal end of the white streak, are two or three white spots and the cilia of the apex of the wing are touched with dark brown. On the middle of the costa is ' a short oblique, dark brown streak. Hind wings and cilia a little darker than the fore wings.

Antennae pale yellowish. Head and face whitish.. Labial pal23i, second joint fuscous externally except at the extreme tip where it is white,- terminal joint white with a dark external fuscous line.

G. medioiuscella.— Fore wings very pale yellowish, with a dark brown spot along the costa, extending from near the basal third of the wing to the fold, ob¬ lique on its internal edge. At its angle on the fold is a blackish-brown dot and

/

another of the same hue obliquely above it on the edge of the spot. Exteriorly the spot is lost along the costa in dark fuscous dispersed atoms, with which the apical portion is dusted. Hind wings shining pale gray; cilia tinted with yel¬ lowish.

Antennse annulated with dark fuscous and whitish. Head yellowish white.

Labial palpi whitish, with two dark fuscous spots on the exterior of the second joint; terzninal joint dark fuscous at the base and thence to the tip dotted with fuscous atoms.

G. fnscopunctella. — Fore wings dark gray, with three dark fuscous spots along the costa; a small one near the base, beneath which obliquely are two small ones of the same hue, one on each side of the fold; one at the beginning of the costal cilia, sometimes indistinct, beneath which, in the middle of the wing, are two dark fuscous dots, one placed above the other; and midway between the two costal spots is a larger costal spot, with a dot of the same hue beneath it in the disc. The largest costal spot and that nearest the base of the wing, are slightly margined beneath with pale brown. The hinder border, at the base of the cilia, has three or four dark fuscous dots. At the basal end of the fold is a dark fuscous dot and another at the extreme base of the costa.

Antennge dark fuscous. Head dark gray. Labial palpi gray; second joint- dark fuscous externally; terminal joint with two blackish rings one near the middle and one near the tip.

G. gilvomaculella. — Fore wings dark brownish, with an indistinct yellowish spot on the costa near the base of the wing; one of the same hue on the mid¬ dle of the costa, extended indistinctly or diffusely to the fold, where there is a blackish-brown spot; a yellowish streak on the costa near the tip, with an op¬ posite one of the same hue on the inner margin. Cilia yellowish. Hind wings dark grayish, cilia grayish-fuscous.

Antennae dark fuscous. Head fuscous, somewhat yellowish in front. Labial palpi dark fuscous, the end of the second joint yellowish-white and somewhat varied with yellowish; terminal joint with the extreme tip, and a short streak about the middle, internally, yellowish-white.

G. longifasciella. — Fore wings dark purplish-brown, with a broad white band, Izeginning on the costa near the base and curving towards the middle of the inner margin, of which it covers at least one-third. Hear the beginning of the cilia of the inner margin, it is constricted or pointed, and then dilates into a white spot behind the tip. Cilia whitish. Hind wings pale grayish; cilia the same.

Antennae annulated with white and purplish-brown. Head white. Labial palpi, second joint dark fuscous, with the tip white; terminal joint white, the extreme tip and middle fuscous.

I have two mutilated specimens from Mr. A. S. Packard, Jr.

G. Labradoriella. — Fore wings dark fuscous, with a white spot on the costa at the extreme base, and two white bands, one near the base of the wing, and inclined towards the anal angle, the other near the tip and parallel with the hinder margin; between the two bands, on the costa, is a rather large white spot.

Antennae dark brown. (The head is entirely denuded of scales and the lab¬ ial palpi have been broken off.)

I have a single specimen from Mr. A. S. Packard, Jr., collected in liabrador. ''

P. Liriodendronella. — Fore wings silvery-white, the posterior portion of the wing pale golden, with a broad pale golden streak along the middle of the wing- above the fold, arising at its base. About the middle of the costa is a pale gold¬ en, oblique costal streak black margined on both sides, which coalesces with the posterior end of the median streak. The costal cilia silvery, containing three diverging black streaks. The apical spot black, with a silvery scale or two be¬ fore and behind it, and at the extreme apex, two black lines in the cilia, diverg¬ ing from the apical spot. In the cilia of the hinder margin is a black, curved line, and at the beginning of the cilia of the hinder margin, is a dorsal silvery spot. Hind wings silvery-gray; cilia the same.

Antennae, head, labial palpi silvery-white.

The larva mines the small terminal leaves of the branches of the Tulip-Tree. It is without feet. The body tapers from the head, the terminal portion being slender and pointed, deeply incised, almost moniliform. Head thin and flat. It makes a broad, linear mine oti the under side of the leaves^ leaving a brownish “frass” line. The mine is much contorted and very long, so as often, if not always, to take up the entire under surface of the leaf, winding over it so as to detach nearly all the under epidermis. This is extremely delicate and of a bluish-white color and often the greater portion of it is detached by abrasions.

The larva may be taken from the beginning to the latter part of July. My own specimens were found on the 22nd of July, at which time they were nearly full fed. Taken in the latter part of this month it is very easy to rear the larva and obtain the most perfect images.

TISCHERIA Zeller.

T. Quercitella. — Fore wings orange-yellow, apical portion of the wing red¬ dish-brown, dusted with dark brown. Hind wings pale yellowish, towards the apex reddish-brown and the apical cilia dark brownish.

Antennae, head, labial palpi dark orange-yellow.

The larva makes a white, blotch mine on the upper surface of the leaves of oak in September and October. About the middle of the mine is a spot whiter than any other part, circular and more opaque.

[March

On this spot, when full fed, the larva spins a circular whitish cocoon. The head of the larva is circular; body flattened, tapering posteriorly. Head dark brown ; second segment with a dorsal dark brown spot divid¬ ed by a paler vascular line; body pale yellowish-green, immaculate.

I have before me a single specimen whose wings are not fully grown.

COLIAS	Alexandra, nov. sp.
Male.	Expands from to	inches.	Upper	side bright lemon-
yellow, with a greenish tinge on the	inner half of secondaries; base of

wings and costa of primaries slightly powdered with black scales; fringe yellow.

Primaries have a broad black marginal band, the inner edge of which is usually not crenated, but is parallel to the margin, with a small an¬ gular projection upon the submedian interspace; at the apex it curves slightly and extends a little way along the costal margin, less than in C. Pliilodice; on the inner margin it terminates as in that species; this band is crossed to the fringe by the yellow nervules; on the arc is a narrow black mark, in length not exceeding half the arc, sometimes a little dilated and then enclosing a yellow point.

Secondaries have a narrow margin terminating acutely before the anal angle, crenated within and crossed by the yellow nefvures; some¬ times on the arc is a minute spot of paler color, but this is usually wanting.

Under side: primaries same yellow as above, pale at apex and on in¬ ner margin ; costal margin slightly powdered with minute black scales

and edged witli pale roseate ; discal spot as above ; otherwise immacu¬ late. Secondaries wholly greenish-yellow, covered with black scales ; discal spot small, rounded, silver-white, without a border; otherwise immaculate; nor is there a pink tinge at base as in PMlodice and many species of* Colias ; edge of costa pale roseate to the end of the costal nervure only; fringe of both wings yellow.

Palpi pale yellow ; legs and antennse pale roseate ; club blackish above, brownish-yellow below and at tip.

Female. Expands 2^^^ inches. Upper side less brightly colored, having a greenish tinge throughout, and without a marginal bandi fringe yellow and otherwise as in the male.

Yariety a. Female; expands 2yL inches. Primaries have the apex bluish- white, and an obsolete macular band, indicated only by clusters of scales along the margin and apex and by a line of scales anter¬ ior to these; on the under side of secondaries the hind and inner mar¬ gins have a bluish tint.

From Pike’s Peak ; in the Society’s collection ; 6 males, 1 female. The second female is from the collection of Mr. Gleorge Newman and was taken among the llocky Mountains, some years ago, by Mr. Wood.

Thecla Clothilde, nov. sp.

Male. Expands inch. Upper side fuscous, sprinkled, next the base of primaries, with a few scales of deep metallic blue; on second¬ aries this color extends from the base through the disk to the hind margin.

Under side uniform light greyish-brown, with a silky gloss; a trans¬ verse row of deep orange spots, each edged without by a few dark scales and a whitish border, commences on the costa of primaries, three- fourths the distance from the base, and terminates at the lowest branch of the median nervure; secondaries have a submarginal row of similar spots and a second irregular row crosses the disk; anal angle tinged with orange.

Body fuscous above; blue-grey below; antennae dark with fine white rings; club dark with reddish-brown tip.

hind margin, sinuous within; stigma large, velvet black; from its out¬ er extremity a black line runs along the arc; a reddish-brown patch nearly fills the space between the line and the margin.

Secondaries have the disk tawny more or less shaded with brown along the arc and towards the inner margin.

Under side ochrey-yellow, the dark portions, of the upper surface indicated by a slight reddish or brownish shade; a band of indistinct pale yellow spots crosses the disk of primaries and secondaries have a similar band parallel to the hind margin besides a spot near the base.
