DESCRIPTION OF THE PREPARATORY STAGES OF 

 COENONYMPHA GALACTINUS, Boisduval. 



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



Egg. — Conical, broadly truncated, the flat top covered with a low 

 network of irregular meshes, very fine about the micropyle ; the lower 

 part rounded, almost hemispherical ; the upper part of side and to about 

 two thirds the distance to base ribbed vertically, — about forty low ribs, 

 with fine transverse lines between them ; below the ribs there is an irregu- 

 lar network; color yellow-green. Duration of this stage about 13 days. 



Young Larva. — At 24 hours from egg, length .1 inch; thickest at 2 

 and 3. Dorsum and sides sloping regularly to 13, ending in two short 

 conical tails, which meet at base ; color pale yellow-green, under side 

 more yellow ; a mid-dorsal brown line, and three such lines on the side, 

 the lowest running with spiracles, the next near it, the third at a little 

 greater distance from second and in fact, sub-dorsal ; on each segment are 

 white clubbed processes, each of which rises from a rounded brown tuber- 

 cle ; these form three rows on either side, one sub-dorsal, one mid-lateral, 

 with a demi row between the two on three anterior segments ; in these 

 rows there is one process to the segment ; the third row is at base, over 

 feet and legs, two processes to each from 5 to 11, one each on 3, 4 ; on 2 

 and 12, 13, two hairs to each, in place of processes ; these lower processes 

 are smaller than elsewhere, and less bent, but are turned down ; the upper 

 rows are bent back, except on 2, there forward ; feet and legs color of 

 under side ; head one half broader than 2, rounded, narrowing towards 

 top, depressed at top ; color pale pink ; over the face are a few white 

 tubercles with processes like those upon body, bent down. Duration of 

 this stage 12 days. , 



After First Moult. — At 24 hours, length .19 inch ; nearly same shape ; 

 color yellow-green ; covered with fine, irregular white tubercles, each of 

 which gives a very short hair, all except on 2 turned down and back ; the
