DESCRIPTIONS OF THE LARV.l^: OF SOME MOTHS FROMCOLORADO.By Hakrison G. Dyar,Custodian of Lepidoptera.
With the sanction of the Secretary of the Smithsonian Institution,I spent three months in Colorado in the wuimner of 1901, to investigatethe life histories of some of the moths of that region. As Coloradoembraces several different faunal regions, and as the arid condition ofthe countr}' renders the fauna very sparse and sporadic, different con-ditions are found to obtain there than in the Atlantic region in thematter of collecting. It was found impossible to move about so as tocover various faunal reg-ions without losing the larva? already collectedin one place, owing to the impracticability of keeping a fresh supply offood plants. 1 located in Denver and collected mainly on the prairiesand foothills within 20 miles of that place. Mr. A. N. Caudell, of theDepartment of Agriculture, accompanied me, and was allowed to assistme b\" the permission of the entomologist of that Department.The species of Lepidoptera occurring- in Colorado indicate fourfaunal regions in the State. (1) The prairie fauna occupies all the flatland from the bases of the foothills eastward, probably including- theeastern third of the State and reaching to Texas. It is composedlargely of species peculiar to the region. The ver}' dr}^ condition ofthis land and the sparse vegetation, mostly disappearing early in theseason, with the absence of trees, renders this condition necessary.(2) The fauna of the foothills occupies the hilly and uneven land fromthe bases of the mountains up to timber line. The line of divisionbetween this fauna and that of the prairie is very marked. The foot-hills rise quite sharply from the plains, and within a few paces, almost,the change in the fauna is observable. The foothills have a few trees,pine, and other evergreens, with a dwarf oak, all sparsel}^ distributed;a hard}^ bush, Cerocarpus pannfoUm, seems to prefer the most unfa-vorable hill tops. In the bottoms of the canyons, where water persists,Cottonwood, willow, and other trees occur, often densely, which per-mits the occurrence of many species belonging to the Atlantic regionProceedings U. S. National Museum, Vol. XXV?No. 1290.Proc. N. j\I. vol. XXV?02 24 369

I didnot notice any essential change in the fauna with altitude, from thebase of the foothills (5,000 feet) to timber line (12,000 feet). Natu-rally' the individuals were later to emerge in the higher altitudes, buton the whole they were the same species. (3) The Alpine faunaoccurs on the high peaks above timber line. It is a small fauna, butentirely distinct from the others. It is essentially that of all moun-tain peaks, being comparable with the mountain summits of NewHampshire and with Labrador. (4) The fauna of western Coloradooccupies the valleys west of the continental divide and doubtless extendsto the Sierra Nevada of California and to Mexico. It was impossibleto obtain any larva? from this region, much to my regret. Effortswere made to do so, but proved ineffectual without sacrificing the larvrethat had been collected in the eastern foothills. It is of these latter,with a few from the prairie region, that I have made note.The following is onl}^ a partial list of species observed. Those ofwhich the larvae did not come under observation, even though themoths were collected, are not mentioned. Besides the 69 species herenoted, I have given full life histories of 10 species of Geometrida? in"Psj^che," descriptions of the larvsB of 3 species of Dejjressariain Mr. Aug. Busck's paper on that genus, 5 species of Gelechio in Mr.Busck's article on the Gelechiidfe, and of Trijyrocris smithmnianuxin the Proceedings of the Entomological Society of Washington. Anumber of species were noted but not bred, and there remain severalnot yet satisfactorily determined, to which I shall revert when theopportunity offers.

Spinesall long, some sette white; spiracles black, the elevated spots behindthem on joints 5 and 11 reddish.This larva is well known in the Atlantic coast region from Massa-chusetts to Florida and has been often desci'ibed. The .voung larvtewere found gregariousl}^ on the oak on May 20, in a gulch leading upfrom the Platte Canyon. They were matured about the 1st of July.No moths were bred, but I can not doubt the identification, as the larvais very familiar to me.HEMILEUCA NEVADENSIS Stretch.Za/'ri/.?Head, plates, and feet very bright mahQg"aiiy red; width4.5 mm.

Several werefound on willow near Denver by a water course in the prairie, andwere matured about the 1st of July, A moth emerged in Septeni1)cr.The occurrence of these two species within a few miles of each other,but in different fauna! regions, is interesting, both as illustrating thatthe}" are different species though so similar, and how the Atlanticcoast fauna is interpolated in the middle of the Western one along thefoothills of the Rocky Mountains.

Moths emerged August 8, fromeggs o])tained from moths flying in the foothills June 27.HALESIDOTA MACULATA Harris, variety ALNI Henry Edwards.This species occurs in three forms in the United States. Thoseinhabiting the northern Atlantic region and the northern Paciticregion, respectivel.y, are indistinguishable in the moth state, thoughdifferent as larvaj. I have several times received II. maculata fromColorado, but never knew to which race to refer the specimens.

This side has a single medianimpressed groove; the lower side two such grooves. Twelve broad,longitudinal, raised ridges join a similar ridge about the rim of thetruncation, ])roadly waved, rounded, beaded with a double row ofminute pores, joined by difiuse transverse ridges to form squares andalso by numerous fine, obscure, transverse lines, about eight to thesquare. Beginning one square from each end the two central ridgesare approximated, the space between depressed as a deep, smoothgroove. On the other side the two median hollows are depressed,their bordering ridges less shai*ply approximate, the grooves crossedby strife. In one egg the double grooves began, one of them at onesquare, the other at two squares from the truncation, but both endedsharply and evenh^ at one square from the other end.

I had no expectation of finding a slug caterpillar in Colorado, as theclimate seems too dry. However, Mr. Caudell netted a female mothin a narrow, wooded gulch leading ofi' from the Platte Canyon, not farbelow Bear Gulch. The moth differs only slightly from the EasternTortricidia testacea^ being paler and less strongly dark shaded, but thelarva shows some rather unexpected differences, showing it to be adistinct local variety of that species. The pattern of markings is moregeneralized in the Rocky Mountain race.J^^ggs.?Elliptical, flat, but rather thick and arched, translucent,slightly yellowish, the reticulations obscure; size, 0.8 by 0.5 mm., allas usual in the family.Stage /.?As in the Eastern species, the subdorsal spines Y-shaped,the anterior prong shortened on the hinder segments, especially onjoint 11; not strongly alternating, yet perceptibly so; greenish trans-lucent, the ridges whitish; head green, eye black, mouth brown; skinsmooth.

The wide dissimi-larity of the larvfe ( O. periscelidactylus has warts and secondary hairs)led me to reexamine the moths. 0. delmvarieus is extremely similarto O. periscelidactylus, much more so than the descriptions by Wals-ingham and Fernald would imply. It is smaller, the palpi are shorter,the antenna^ completely white ringed, and the space between the whitelines on the feathers of the fore wing is dark brown, contrasting withthe rest of the wing.

Found at Golden andBoulder, near or on the prairie. iThe United States National Museum has fragments of two speci-mens, one labeled in Zeller's handw riting, the other taken by Belfragein Texas, July 2. Mr. Busck thinks that they ma}' have been part ofZeller\s types; they certainly agree with his description. My speci-mens run larger, though some are of the same size, and the bandingon the fore wings is heavier, not being so much confined to the costaledge as in Zeller's specimens. But the sexes are marked alike, whichconfirms me in the determination, as it is an unusual chararter in thisgenus.

' Professor Fernald identifies this species with the European 0. diana. I have seenbut two specimens of this rare species, and both differ from the American form, ofwhich I possess now a large series. Our moths are very dark, with no trace of thegreenish overlying scales of the European ones. They may, perhaps, be separatedunder the varietal name hetuliperda.

At the Half Way House on the Pikes PeakRailroad, at a similar altitude to the places where this species occurredso abundantly farther up the range, no specimens were seen and thebirches were uninjured. The species, therefore, seems to be local inits appearance. Prof. C. P. Gillette spoke to me of this species asone that he had long observed to be destructive to the birch.The larva lives under a delicate web which it spins over the surfaceof a leaf, Keld above the surface by the curl of the leaf. It eats theparenchyma on the upper side, skeletonizing the leaves, which becomebrown and dry.

Larva? active, jumping oti' the leaves whendisturbed.The moths resemble the European Cerostonui radlatella Donovan,which has been recorded also from America. They are similar inshape and size, and are like one form of that variable species in color-ation. But they are not variable, my 12 specimens being absolutelyuniform, besides which the larva and food plant are difl'erent. I have,therefore, thought them deserving of a distinct name.Palpi clothed with black and a few white scales, longer at the end ofthe second joint; face black and white scaled; vertex with long redbrown vestiture, basal joint of antenna? and neck narrowly white;antennte white and black banded below.

Theterminal leaves of a young growing tip become united into a fusiformgall-like enlargement, forming a tight box. Every leaf or part of onethat touches the inside of the cavity of the box is swollen in that partof its surface; the swollen parts become yellowish and the leaves adheretogether, forming the four or Ave sided box. The tip of the stembearing the box is recurved. Larva within the hollow, destroying theInid. Frass in the pointed tip. These curious formations, lookinglike large flower buds, were found commonly in a few places in thePlatte Canyon and on the prairie near Denver. When occurring atall, they were generally abundant. They were not found, however,until too late in the season to be successful in rearing the moths. Still,they seem obviously to be the same as the species described by Mr.Busck . .As Mr. Busck's paper on the Gelechiida?, in which his descriptionwould naturally appear, is delayed, I have asked him to furnish thedescription in advance, which he has kindly done. 1 append it.GNORIMOSCHEMA COQUILLETTELLA Busck, new species.Antenna- dark brown with narrow silvery wliite annulation^^.
