226 THE CANADIAN ENTOMOLOGIST. 



turn low, rounded, with a slight carina, and followed by a slight excava- 

 tion ; color, apple-green ; a white stripe along side of abdomen to 

 extremity. Duration of this stage nine to ten days. 



Boisduval's type male is described as having the yellow replaced by 

 vivid orange, and the fore wings as having a violet reflection. This is the 

 form figured in But., N. A., Vol. I. But many are utterly without any 

 sort of reflection, and the dog's head is ochre-yellow. 



Mr. Henry Edwards, in Proc. Cal. Acad., Dec. i8, 1876, called atten- 

 tion to the var. Amorphie of Eurydice, and speaks of it as the autumn 

 brood of Eurydice, distinguished by a decided black marginal border to 

 hind wings of the male, and by brown patches upon the marginal border 

 of the female. It is a seasonally dimorphic form rather than a variety. 

 Mr. Edwards discovered that Amorpha Californica was the food plant of 

 Eurydice, and described some part of the transformations in Proc. before 

 cited, June 5, 1876. He notices that the caterpillar refused all other 

 plants offered by him. The mature larva and chrysalis are described. 

 I see that Mr. Edwards gives the length of the larva as 1.45 inch, and of 

 the chrysalis .95 inch. The largest larva which I have seen had a length 

 of only I.I inch, and the chrysahs of .8 inch. It may be that the larva of 

 spring brood is smaller than the fall brood. All my larva were of 

 the spring. Mr. W. G. Wright, of San Bernardino, sent me several 

 eggs by mail, which hatched on the road, and the larvae reached 

 Coalburgh 2nd April, 1883. On 23rd April, I received quite a num- 

 ber of larva of all stages from first to last ; 24th April, came another 

 lot of larva. With each lot came a supply of the food plant, and boxes 

 of this were sent me repeatedly, and till I announced that I wanted no 

 more ; also plants with roots were sent, and these I succeeded in saving, 

 and before fall had three large bushes four feet high. I tried, in vain, to 

 make the larva eat clover. Their habits are similar to those of Philodice. 

 When first hatched, they eat furrows in the surface of the leaf; by first 

 moult eat the leaf itself; always lie extended on the upper side along the 

 mid rib. There is not the slightest difficulty in raising them to chrysaHs, 

 if one has the plant. 



The several stages of this butterfly — egg, larva from egg to pupa, and the 

 pupa, are closely like those of other Coliads, as Philodice, Eurythenie, &c. 

 There is no generic difference whatever observable in any of these stages 

 between Eurydice and Philodice. and so far as my observations with Diurnal
