THE CANADIAN ENTOMOLOGIST. 23 



wholly green, some green with yellow bands, some with black bands and 

 no yellow, but more have both black and yellow, with variation as to 

 extent of either : the black bands appeared at fourth moult in examples 

 which showed no trace of them in previous stage, and some larvae wholly 

 green to end of fourth stage, at the moult took on all the bands ; under 

 side, feet and legs pale green ; head round, slightly depressed at top, with 

 many fine black points, each with short, black hair ; color yellow-green* 

 From fourth moult to pupation about six days. 



Chrysalis. — Length .8 inch ; breadth across mesonotum .18, across 

 abdomen .18 inch; greatest depth .24 inch; shape of Eurydice; com- 

 pressed laterally, the thorax on ventral side prominent, rising to a narrow 

 ridge ; the abdomen tapering, conical ; the mesonotum low, rounded, with 

 a slight carina, followed by a shallow excavation ; the head case produced 

 to a point, a little curved up, with a regular slope on both dorsal and 

 ventral sides, angular laterally : color bluish-green over whole dorsal side, 

 below, the abdomen yellow-green ; the wing and head cases dusky green, 

 on the under side a brown crescent ; on dorsum two rows of black dots 

 from mesonotum to 12, one to each segment, and a small black spot on 

 either side abdomen ; the whole surface except wings dotted or finely 

 streaked whitish. 



Another example gave same dimensions j the dorsum yellow-green, 

 ventral side of abdomen more yellow ; a brown patch on under side of 

 head case. Duration of this stage seven to ten days. 



CaesuNIA is a common butterfly in the Mississippi Valley and Gulf 

 States ; also in Southern California and to the Isthmus. I myself have 

 never seen it on the wing, and the above descriptions are drawn from 

 larvae sent me during the season of 1887, by Mr. R. R. Rowley, of Curry- 

 ville, western Missouri. The first lot of larvae were received 2nd August, 

 mostly young, and with them eggs which hatched a day or two after. On 

 1 ith Aug , there came about twenty larvae of all stages to mature. Again, 

 on 26th Aug., came eggs and young larvae, and more on 8th October. 

 The food plant was Amorpha fruticosa. In California it is Amorpha 

 California, and I was able to feed the larvae from plants of this last 

 growing in my garden. The behavior of the larvae is in all respects as in 

 Eurydice, Philodice and other species of the genus. 



A noticeable feature of these larvae is the variation in markings,
