Fig. 291. 



The Genus Ellema is smaller than the preceding. A 

 Harrisii, Clemens, flies the last of June. 



The Genus Smeriuthus has the wings scalloped or 

 notched, and the tongue very short. The caterpillars 

 are rough, with a stout thorn on the tail. 



The Blind Smerinthus, vS. exccecata of authors, expands 

 about two and a half inches, is fawn-colored, clouded with 

 brown, except the hind wings, which are rose in the mid- 

 dle, and have a black eye-spot with a blue centre. 



The Genus Sesia 

 contains the Clear- 

 winged Sphinges, 

 which are distin- 

 guished by their 

 transparent wings 

 and broad tails. 

 They hover over 

 flowers like hum- 

 sia, s. thysie, Fabr. ming-birds in the 



daytime, in July and August. 



JEGERIDJE, Stepk. This Family comprises moths which 

 have the body large, wings mainly transparent, and, in a 

 state of repose, about half erect. The larvae bore the 

 stems of trees and shrubs. 



The Genus Trochilium is hornet-like in appearance, 

 with the antennae thickened nearly to the end, which 

 is curved but not hooked. The Peach-tree Borer, T. 

 exitiosa, Say, expands about an inch and a half, the fore 

 wings are blue and opaque, the hind ones transparent, 

 and the middle of the abdomen has a 

 broad orange-colored belt. The male has 

 all the wings transparent, bordered and 

 veined with steel-blue, which is the gen- 

 eral color of the body in both sexes. The 

 Peach-tree Borer, T. female deposits her eggs in summer on the 



exitiosa, Say.
