CCENONYMPHA I. 



red-brown ; head greenish-yellow, with a tint of brown over face. (Fig. /.) 

 From third moult to pupation about twelve days. (The larval measurements 

 were taken at from 12 to 24 hours from the egg or moult.) 



Chrysalis. — Length .36 inch; breadth at mesonotum .14, at abdomen .16 

 inch ; very much as in Satyrus Aloj^e, the ventral side sti'aighter, the abdomen 

 more swollen, less tapering; cylindrical, stout, the upper end truncated, the 

 abdomen conical; head-case narrow, ending in a sharp cross ridge which is a little 

 arched at top, the sides roundly excavated ; mesonotum prominent, arched, the 

 carina rounded transversely, the sides slightly convex, followed by a shallow 

 depression ; color — from green larva — yellow-green, over dorsum and abdomen 

 finely specked with white ; marked by nine black stripes of irregular length ; of 

 these, there is one on dorsal edge of each wing-case from base to inner angle ; a 

 curved stripe on middle of same reaching the hind margin ; a short one on hind 

 margin on ventral side, two parallel short ones on the antennae cases, and a larger 

 on ventral side between the wings; there is also an imperfectly colored black 

 stripe on either side of 13 (in the figures this is too black and distinct); top of 

 head case whitish with a dash of black below on dorsal side. 



From buff larva ; color pinkish brown, no decided marks, but the curved wing 

 stripes appear in a deeper shade of brown. One chrysalis fi-om a buff larva was 

 green, but the wing cases were buff ; and it was fully striped black. Another, 

 also from buff larva, was pinkish at first, with three darker stripes on dorsum in 

 addition to the nine before described, which last were faint brown; the three 

 were, one on mid-dorsum below the excavation, and one on either side this ; in a 

 day or two the chrysalis had changed to full green, with the nine distinct stripes 

 as usual, but the three additional ones had disappeared. Another was wholly 

 green, with no stripes or traces of them. (Fig. 9.) Duration of this stage eleven 

 and twelve days. 



The two forms Galacthms and California, or Californius, are of one species, as 

 has been proven by breeding from the egg, Galacthms being the winter, the other 

 the summer form. And although California, Westwood-Hewitson, has the prece- 

 dence of one year, yet I call the species Galactinus, because the winter form of 

 a dimorphic species is regarded as the primary form, the only form when the 

 species was single-brooded, and the summer form as secondary and derived from 

 the other. 



On 1st May, 1885, I received thirteen eggs laid by Galactinus in confinement, 

 from Professor J. J. Rivers, at Berkeley, California, and which had been mailed 

 23d April. They began to hatch 5th May. On 7th May, I received a second
