DESCRIPTION OF PREPARATORY STAGES OF ARGYNNIS 



ALCESTIS, Edw. 



BY W. H. EDWARDS, COALBURGH, W. VA. 



EGG — Conoidal, truncated, not so broad at base as Idalia, the sides 

 less rounded ; depressed at summit ; marked vertically by about eighteen 

 prominent, slightly wavy ribs, half of which extend from base to summit 

 and form around the latter a serrated rim ; the remainder end irregularly 

 at two thirds to three quarters distance from base, sometimes squarely at 

 one of the striae, but usually curve towards and unite with the long ribs ; 

 between each pair of ribs are equi-distant transverse striae. Shape of 

 Aphrodite and Myrina, being more slender, narrower at base, and less 

 convex on sides than the other large species of this genus. In Mrs.

YOUNG LARVA — Length .08 inch ; cylindrical, thickest anteriorly, 

 tapering backward, the dorsum sloping considerably ; color brownish- 

 green, translucent; each segment from 3 to 12 marked by eight rows of 

 tubercular dark spots, six of them placed on dorsum and upper part of 

 sides, each spot giving out a long black clubbed hair, which is curved
