PSEUDOHAZIS SHASTAENSIS Behrens. 



Larva. — Head high, tapering conically, clj^peus low, sutures 

 impressed, erect, free, shining black; width 4.5 mm. Body purplish 

 black witji faint traces of white lines, the subventral the most distinct; 

 secondary hairs tine, pale, with imperceptible tubercles. Upper row 

 of spines shoilened on joints 5 to 12, most of the spinules buU' yellow; 

 some buff ones also on the not shortened upper spines of joint 4; other 

 spines black; no white dots on the body. 



The larvffi were found, gregarious when young, on rose and wild 

 cherry on the foothills back of Golden. They were matured about 

 the middle of July. Pmudohazls occurs all through the West, but 

 there are three forms or species. The one occurring on the eastern 

 foothills is the one with pink ground color in the fore wings that I 

 Q.i^shastaeiuU., as proved l)y examples in Prof. C. F. Gillette's collection. 



Family ARCTIID.F. 



APANTESIS SUPERBA Stretch. 



Larva. — Head shining black, lalu'um yellowish, antenna^ pale, pink- 

 ish at l)ase; width 3.3 mm. Body black, thoracic feet black, the abdom- 

 inal ones pinkish, pale. Warts large, normal, arcfciiform, i and ii with 

 shining bases, i over half as large as ii, which is elongate. Hair al)un- 

 dant, bristly, sparsely barbuled, rather short before, long on joints 12 

 and 13; most of the hair from wart i and a few on the sides of ii are 

 yellow, below this jet black mixed with white, mostly white from 

 warts iv to vi. Warts iii orange, the rest black. A light yellow dor- 

 sal line, broken into three spots on each segment, distinct, most of 

 them lanceolate; a line on joints 2 and 3, no shields; joint 2 with lit- 

 tle warts, normal. - 



A Viiriety had the dorsal line nearly o))solete, composed of a few 

 dots; wart iii black like the others. Hairs nearly all yellow, only a 

 few ))lack ones mixed; some longer Avhite ones posteriorly. 



Found at Boulder and Golden in the foothills on theground or feed- 

 ing on low plants, Astragalus and Luj)i?u/s. The larva3 were very lively 

 and would run for shelter when discovered. They became matured in 

 June, apparently from hibernated larvae. Moth, July 13. Though 

 not uncommon they were bard to rear, and only one female was 

 obtained. I think, however, that this is the larva of A. l7icorrujjta, of 

 which 1 have only males. 



A parasite, Tachina inella Walker, was ))red from one larva. 



APANTESIS FIGURATA Drury. 



Larva. — Head shining black, epistoma and bases of antennae pale; 

 width 2.7 mm. Body brown-black, the abdominal feet pale reddish. 

 A broad, distinct, sharp dorsal line, narrowed between warts i, cream
