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

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

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

 in Canada, from the genus Macroglossa, repre- 

 sented in Europe by M. steUatarum Linn. 

 Mr. Grote also separates from the latter 

 genus, under the name of EitpyrrJioglossinn, Fig 205.

^GERiAD^ 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 antemiie, and by the tufts at the 

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

 verj' swiftly in the hottest sunshine. The larviie are borers, 

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

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

 tlu'v 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 pupte are 

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

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

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

 the moth. The shell of the chrysalis is often left jM-otruding 

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

 gardeners.

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