﻿126 CLEMENS' SYNOPSIS OF 



The eggs of the perfect insect are deposited singly on the food-plants of the larvae, 

 which are usually conspicuous in size when full grown, and live a solitary life. They 

 have naked, cylindrical bodies, varying slightly in form, and presenting, usually, 

 differences of ornamentation in the several genera. They possess eight pairs of feet, 

 three of which are thoracic, four abdominal and one terminal ; the latter are large, 

 strong and almost square, with the plantse situated at the anterior angle. On the 

 dorsum of the eleventh segment is placed a rigid spine, called the caudal horn, and 

 when this is absent it is replaced by a lenticular tubercle. 



The pupoa are cylindrico-coriical, with the extremity of the abdominal case termi- 

 nating in single, stout, acute spine, and is contained in an imperfect cocoon, or near 

 the surface in a cell, or in a subterranean cell.
