the true legs bunched together. In all instars the young 

 tender leaves are ignored and only old hard leaves eaten, 

 round holes being bitten between the side-veins, or the whole 

 portion between two side-veins being removed. Before 

 pupation the body becomes suffused with pink, and the larva 

 leaves the food -plant and hurries about looking for a suitable 

 place to pupate. At this period it jumps when touched like 

 the larvae of the genus Oxyambulyx, and the body is very hard 

 and firm. Pupation takes place in a cell underground. The 

 pupa is very lively, and moves the abdomen freely when 

 handled. The moth rests with the wings horizontal and held 

 so that the lobe of the hind wing projects well in front of the 

 costa of fore wing, the abdomen being left uncovered and 

 bent upwards. It is very sluggish during the daytime, and 

 does not take to the wing for a long time after emerging from 

 the pupa, but when it does so the flight is rapid. When 

 handled it bends the long abdomen about as though attempting 

 to sting. We have not seen the moth feeding, nor does it 

 appear to be attracted by light. It emerges about two to 

 three weeks after pupation, except when the pupa is formed 

 about October. These late pupae hibernate, and the moths 

 emerge in the following spring.

Imago. — (J$. Large handsome moths with body and fore 

 wing green, hind wing crimson. " Tongue short, weak, 

 fringe at the mesial edges long. Pilifer somewhat swollen, 

 with bristles. Genal process subglobose. Palpus slender,
