 DilepJiila includes a number of species of moderate size, 

 measuring three or four inches across the wings, with rather 

 small conical heads, thick antennae, and very stout and 

 rather short bodies. The wings are broader and shorter than 

 in Chcerocampa and its allies, and the fore-wings are usually 

 marked with a more or less irregular whitish band, running 

 from near the base to the tip ; the hind-wings are black, with 

 a rosy band. The larvce feed on Euphorbia, Galium, &c., and 

 are spotted on the sides, but are seldom marked with ocellated 

 spots, nor are the anterior segments attenuated and retractile. 

 The pupa is formed on the surface of the ground among 

 leaves, but is always more or less covered with soil. 



This is a compact genus of moderate extent, and is repre- 

 sented in most parts of the world, but the species are most 

 numerous in the Mediterranean Region. We have three 

 species in England, but although they all breed here, it 

 appears doubtful whether they could perpetuate themselves 

 in England if they were not reinforced by fresh arrivals from 

 the Continent.
