LARV.E OF MOTHS FROM COLORADO— DYAR. 389 



Segments finely obscurely annulate; setse short, stiff, black; no 

 shields. 



The larvre were not carried to maturity. The eggs came from a 

 female taken in the mouth of Platte Canyon in the foothills, and their 

 food plant was made out so late that they had been four days without 

 food and were so weakened that they died in the second stage. The 

 food plant is vnolet, but it was only after repeated efforts that this 

 was discovered and a whole da}^ spent in a special journe}- to the spot 

 where the moth had l)een caught. 



HYDRIOMENE TRIFASCIATA Borkhausen. 



Larva. — Head rounded, free, light brown, sparsely mottled, dotted 

 with dark; tubercles darker, as are the sutures and eyes; width about 

 2 nun. Body robust, flattened cylindrical, normal, smooth. Whitish 

 like the oak-feeding Tortricids and Pyralids, more yellowish white on 

 the ventral half, dorsum somewhat streaked on the annulets. A sordid 

 blackish-green dorsal vascular stripe; an olivaceous luteous, rather 

 broad, stigmatal stripe, red-brown at the spiracles. Tubercles sor- 

 did, blackish, moderate. Feet pale, shields concolorous, uncornified; 

 tubercle iv substigmatal, posterior, faintly broadl}^ whitish ringed. 



The larva? occurred on the oak, hiding between leaves and with the 

 aspect of Pyralids. but true Geometrids in structure. They were found 

 by Mr. E. J. Oslar, at Cheyenne Canyon, near Colorado Springs. 



SCIAGRAPHIA PERVOLATA Hulst. 



Larva. — Head rounded bilolied, the lobes squarish, erect, flattened 

 a little before; gray white, a broad black band over the vertices of 

 the lobes and another across from eyes, but leaving the epistoma pale; 

 black dots between the bands; width 1.8 mm. Body normal, not 

 greatly elongate; tubercles elevated; setfe coarse and black. Bark 

 gray; ground color whitish dorsally, but gray between tubercles i and 

 ii; a reddish subdorsal band broken into spots below tubercles i andii, 

 the rest whitish. Lateral area gra}^ mottled, the substigmatical fold 

 white anteriorly on the segments; venter marked and dotted with gray- 

 ish black. Tubercle vi double, or of two separate tu])er('les; i and ii 

 nearly in line, the rest as usual; the tubercles of vii moderately sepa- 

 rated. Plates spotted like the body, uncornified. 



Found on wild gooseberry in the Platte Canyon, May 18; imago 

 June 12. I am not sure that the moth is correctly naiued. I could 

 not find any description to exactly fit the specimens; that of S. per- 

 volata seems the nearest. The moths have the wings whitish gray, 

 rather coarsely brown strigose; transverse anterior and posterior lines 

 represented by diffuse clouds, the latter bent outward opposite the 

 cell. A black patch at costa and at middle of wing occur just beyond 

 the transverse posterior line and adjoin a broad, pale, ill- defined sub
