SESIID^. 7^ 



of small and very beautiful exotic species — Eretmocera, &c., 

 which have hitherto been placed among the Tineina. In 

 another direction the present family is more distantly con- 

 nected by means of the brilliant genera Euchromia and 

 Syntomis, and many other lovely and wonderful forms, with 

 the Zyggenidse. 



The resemblance of the species of the present group to 

 various species of Hymenoptera and Diptera and particularly 

 to the Ichneumon- flies, is most extraordinary ; and has, in 

 many instances, suggested the specific names. 



Genus 1. SESIA. 



Antennoe very gracefully curved, thickened in the middle, 

 tapering to a long point ; furnished in the male with short 

 tufts of bristles in pairs on the under side of the shaft ; 

 these tufts, though in some species extremely short, being 

 thick and regular ; apex of the antennae with a tuft of longer 

 bristles. Fore and hind wings very narrow ; abdomen long 

 and slender, with a broad anal tuft. 



Larv^ soft and fleshy, with short pro-legs. In the bark, 

 shoots, or twigs of trees and shrubs, and the roots of low 

 plants. 



Pup^ very slender and active, moving by means of 

 abdominal and anal spines. 



A table of the species may be useful.
