GENUS DEILEPHILA. 



THE species included under this appellation, wh}ch 

 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 

 antennae, which are rather short, thickening at the 

 apex so as to form a distinct club, and having the 

 terminal hook ending in a naked tubulated seta. 

 The proboscis is long and spiral, but 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, but 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.
