Genus Pholisora 



a pale submarginal whitish line. The under side of the wings is 

 pale, with the light markings of the upper side indistinctly sepa- 

 rated. Expanse, I. lo-i. 25 inch. 



Early Stages. — Unknown. 



This interesting little species occurs in Arizona and northern 

 Mexico. 



Genus PHOLISORA, Scudder 



BiitterJJy. — The palpi are porrect, the second joint loosely 

 scaled, the third joint slender and conspicuous. The antennae 

 have the club gradually thickened, the tip blunt. The fore wing 

 is relatively narrow, provided with a costal fold in the 

 case of the male. The cut gives a correct idea of the 

 neuration. 



Egg. — The Qgg is curiously formed, much flattened 

 at the base, marked on the side with longitudinal 

 ridges and cross-lines, these ridges developing alter-

and surrounding the deeply depressed micropyle. 



Caterpillar. — Slender, with the head broad, rounded; the 

 body stout, thickest in the middle, tapering toward either end, 

 and somewhat flattened below. 



Chrysalis. — The chrysalis is slender, very slightly convex on 

 the ventral side, somewhat concave on the dorsal side behind 

 the thorax. The wing-cases are relatively smaller than in the 

 preceding genera.

 Plate VI, Figs. 29, 36, 41, chrysalis (The Sooty-wing). 



ButtcrJJy. — Black on both sides of the wings, with a faint 

 marginal series and a conspicuous submarginal series of light 

 spots on the primaries in the male sex on the upper side, and, in 

 addition to these, in the female sex, a faint marginal series on the 

 secondaries. On the under side only the upper spots of the sub- 

 marginal series of the primaries reappear. Expanse, .80-1.15 

 inch. 



Early Stages. — The caterpillar feeds on " lamb's-quartcr " 

 (Chenopodiiim album) and the Aiuarautacea\ It forms a case for 

 itself by folding the leaf along the midrib and stitching the edges
