LEUCOPHLEBIA. 157 



Habits. — The larvae feed on grasses, family Gramineae, 

 which do not form the food-plant of any other sphingid cater- 

 pillar. They have the same peculiar habit as those of the 

 genera Clanis and Clanidopsis of remaining in the larval state 

 for long periods after they have buried themselves, and are 

 very difficult to breed. The moths rest with the wings held 

 steeply penthouse- wise. 



Hab. Oriental and Aethiopian, with two Indian species.
