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, 1.10-1.25 inch. 
Early Stages. —Unknown. 
This interesting little species occurs in Arizona and northern 
Mexico. 
Genus PHOLISORA, Scudder 
Fig. 159. — 
Neuration of 
the genus 
Pholisora. 
Butterfly. —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 egg is curiously formed, much flattened 
at the base, marked on the side with longitudinal 
ridges and cross-lines, these ridges developing alter¬ 
nately at their apical extremities into thickened, more 
or less rugose elevations, the ridges pointing inwardly 
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). 
Butterfly. —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-quarter ” 
(Chenopodium album) and the Amarantacece. It forms a case for 
itself by folding the leaf along the midrib and stitching the edges
