in the early sjiring, Hitting about the leafless hedges. Most of 

 the species appear at the end of summer, and, after having hyber- 

 nated, are met v\'iLh in March and April in rather wasted condi- 

 tion. There is a peculiarity in the perfect insects of this genus, 

 that they have the power of sliding about when laid on their 

 backs, shooting forwards much in the style of NocUm Tragojiogonis. 

 2^-ct>cc.)5'--i-n <>'}'''■ The larva3 are extremely active, and feed on a variety of sub- 

 ^\X. M ll'^ stances, some feeding in roUed-up leaves of composite plants, 

 some in the leaves and others in the umbels of the Uiiibelll/vra ; 

 many of the latter descend from the plant on the slightest agita- 

 tion of it, and considerable caution is necessary in the attempts to 

 collect them. The full-fed larvffi descend to the ground, and 

 change to the pupa state among the fallen leaves ; the larva of 

 Heradiana frequently enters the stem of the Heraclinm Sjjliotuhj- 

 lium, undergoing its changes there. 



The extreme similarity of many of the species renders the deter- 

 mination of them a matter of some difliculty, and unfortunately 

 the genus hardly admits of a good subdivision; the best I have 

 been able to accomplish is by the following table : — •
