]46 
Genus DEILEPHILA. 
The species included under tliis appellation, which 
is derived from the Greek, and means Lovers of 
Evening, were first dissevered from their associates 
by Hubner, chiefly on account of the form of the 
antenna?, which are rather short, thickening at the 
apex so as to fonn a distinct club, and having the 
terminal hook ending in a naked suhulated seta. 
The proboscis is long and spiral, hut in general it is 
shorter than in the preceding genus. The abdomen 
is comparatively short and of a conical shape. . The 
anterior wings are not very acute at the apex, the 
hinder margin slightly and regularly rounded, with- 
out any sinuosity. The caterpillars are similar in 
shape to those of the genus Sphinx, hut their 
colours are distributed in spots ; the anterior seg- 
ments are not retractile. The pupa is always more 
or less covered with soil. The abdomen of the 
perfect insects is banded transversely at the base, 
the other bands interrupted on the back and forming 
only lateral spots.
