above the row of stigmata, and a short recurved horn. It 

 transforms in an imperfect cocoon at the surface of the earth. 

 Sesia diffims Boisd. is pale greenish yellow, with the abdomen 

 black beneath, and the legs black. The larva is 

 pale green, reddish beneath. Sesia Tliysbe Fabr. 

 is a more common species northward. The thorax 

 is deep olive green, with the abdomen reddish be- 

 neath, and with whitish legs. It is abundant, flying in June 

 in the hot sun about the lilac and Rhodora Cauadensis. 



Under the name of Lepisesia Mr. Grote has separated L. 

 flavofasciata Barnston (Fig. 204, venation of fore-wing) found 

 in Canada, from the genus Macroglossa, repre- 

 sented in Europe by M. stellatarum Liuu. 

 Mr. Grote also separates from the latter 

 genus, under the name of Eupyrrhoglossum, Fig 205.

 wings than in Macroglossa. E. Sagra (Fig. 205, venation of 

 fore-wing) is a handsome form described b}*- Professor Poey. 



Harris. These elegant and gaily colored moths, 

 which by the arrangement of their colors and their clear wings, 

 look like bees and wasps, are readily recognized by their small 

 size, narrow wings, thickened antenna?, and by the tufts at the 

 end of the body, which they can spread out fan-like. They fly 

 very swiftly in the hottest sunshine. The larvae are borers, 

 living mostly in the hollowed stems of plants. They are whit- 

 ish, cylindrical, with sparse, short, inconspicuous hairs, and 

 they have no anal horns. They transform in a rude, oblong, 

 oval cocoon, constructed of the chips they make in boring out 

 their tunnels, cemented by a gummy secretion. The pupa? are 

 chestnut-brown, with transverse rows of short teeth on the 

 abdominal rings, by which they make their way exit, partly 

 through the hole previously made by the larva for the exit of 

 the moth. The shell of the chrysalis is often left protruding 

 from the hole. This family is, therefore, quite injurious to 

 gardeners. 



^rEgeria exitiosa Say (Fig. 206, $) the Peach-tree borer, has 

 caused the death of many peach trees and also, according to 

 Fitch, occasionally attacks the plum. It is a slender, dark
