DESCRIPTION OF THE PREPARATORY STAGES OF 

 COENONYMPHA AMPELOS, Edw. 



BY \V. H. EDWARDS, COALBURGH, WEST VA. 



Egg. — Conical, truncated, the top nearly flat, slightly depressed, cov- 

 ■ered with a fine network of irregular six-sided meshes ; these form four 

 rings about the central rosette, in middle of which is the micropyle ; the 

 lower part and base rounded and thickly covered with shallow indenta- 

 tions ; the sides ribbed, the number of ribs about 34, vertical, slightly 

 sinuous, more so at lower end, narrow, with rounded spaces between, 

 which are crossed by many fine lines ; color yellow-green. Duration of 

 this stage about 12 days. The egg is like that of Galadinus^ but has 

 fewer ribs. 



Young Larva. — Length, at 24 hours from egg, .11 inch : cylindrical; 

 thickest at 2 to 4, tapering on dorsum and sides to 13, ending in two 

 short, conical tails, which meet at base ; color pale yellow-green ; a mid- 

 dorsal reddish line, and three similar lines on the side, the upper one sub- 

 dorsal, the lowest running with the spiracles, and the middle one nearer 

 the lowest ; surface covered with fine white tubercles, which give appressed 

 downy hairs ; among these are white clubbed processes, all bent back, 

 except those on 2 ; these form three rows on each side, one sub-dorsal, a 

 mid-lateral, with a demi-row on 2 to 4 between the long rows ; in all these 

 one process to the segment ; the third row is at base, over feet and legs, 

 two processes on each, from 5 to 11; one each on 3 and 4 ; on 2, 12, 13 

 two hairs to each, in place of processes ; these lower processes are 

 smaller, and turned down ; head one half broader than 2, rounded, nar- 

 rowing toward top, a little depressed, ^granulated ; over the face a few 

 white tubercles with processes as on body, bent down ; color pink-brown. 

 Duration of this stage about six days. 



The young larva is in all respects like Galactinus, except slight differ- 

 ences in coloration. 



After First Moult. — Length, at 18 hours from moult, .2 inch ; nearly 

 same shape ; color yellow-green ; surface thickly beset with white tuber- 

 cles, and downy ; a mid-dorsal green line, three similar ones on side, the 

 two lower nearest together, the lowest being next over the basal ridge,
