Thk SmermtH have frequently been confounded 
■with the Sphinges, hut they present a sufficient 
number of distinctive marks to entitle them to he 
regarded as a separate generic group. Of these 
the most important are the shortness of the pro- 
boscis, -which is scarcely perceptible, the angulated 
or dentated margin of the anterior -wings, and the 
serrated antennre. The species are not numerous ; 
most of them are of sombre colours ; and they are 
dull inactive insects, seldom appearing on the -wing, 
and when they do so, displaying none of the 
vivadty and rapid movements of the kinds to 
which, in other respects, they bear a close affinity. 
The shortness of their trunk renders them incapable 
of feeding while on the wing like the Humming- 
bird Hawk-moth; the little food which they re- 
quire during their brief existence, is therefore
