CCENONYMPHA I. 



Both sexes are lighter colored than Galactinus, nearly white, there being no 

 dark shade over upper surface, and no black at base ; beneath, the general color 

 is yellowish, the extra-discal areas being nearly or quite free from black scales; 

 the basal half of secondaries pale brown, slightly dusted black ; the ocelli same.

Var. Eryngii. 



This variety differs from California simply in being of a more yellowish hue 

 on both surfaces, the basal areas on under side scarcely darker than the rest; 

 and in tlie absence of ocelli, which is usually total ; some examples, however, 

 have traces of ocelli, as seen in Figure 9. 



Egg. — Conical, truncated, the flat top covered with a low network of irregu- 

 lar meshes, very fine about the micropyle ; the lower part well rounded, with a 

 netted and indented surface ; the sides ribbed vertically, the ribs low, narrow, in 

 number about forty, of which several end at from one third to four fifths the dis- 

 tance from base ; color yellow-green, with ferruginous specks here and there. 

 (Fig. a, micropyle a\) Duration of this stage about thirteen days. 



Young Lvrva. — Length .1 inch ; from 2 both dorsum and sides slope regularly 

 to 13, which ends in two .short, conical tails, at the end of each of which is a process 

 like those on dorsum; color pale yellow-green, the under side less green, more 

 yellow ; on mid-dorsum a brown line, and on either side three such, one sub- 

 dorsal, one on middle, less distinct, and a third running with the spiracles ; on 

 each segment are six white processes, each process from the summit of a conical 

 brown tubercle, forming six longitudinal rows, three on either side ; those of the 

 dorsal rows are club-shaped, much thickened at end, of the sub-dorsal rows are 

 more slender, of lower row, which is just above the spiracles, of equal thickness 

 throughout ; on 2, 3, 4, the processes are nearly in cross line, but on 4 to 12, they 

 foi-m a triangle on each segment, the dorsal one being on the front, the sub-dorsal 

 on the rear, the other on second ridge ; on 2 the j^rocesses of the two upper 

 rows are on front, and between them on the rear is a third ; in front of the spira- 

 cle are two, the upper one short, and like the others of the lower row, but the 

 second one is long and tapers like a hair ; on 13 are fourteen processes, six 

 being dorsal, three to each row, and four lateral, two to either side ; two at the 

 ends of the tails, and two in the hollow between the tails; (in Fig 6 one process 

 on 13 is by oversight omitted ; its place is near front of the segment in the lat- 

 eral row ;) along the base is a row of very short processes, two on 2, one on 3 and
