128 THE CANADIAN ENTOMOLOGIST. 



Viburmim, Vacci?iium, Loiiicera, the genera with angulated wings and the 

 Choerocampinae generally are grape-feeders. Everyx and Ampelophaga 

 spin surface cocoons like Hemaris. The colors of the lower Macroglos- 

 sinae are brown and green, with here and there light yellow, as on the 

 secondaries of Danum and Abbotii. Claret red, olive green, sericeous 

 yellow, are the tints of the first two Subfamilies, with rich browns and 

 hard red tints ; the gray colors of the Smerinthinge and especially of the 

 typical Sphinginee are not as yet displayed. I think that, from the pupa- 

 tion, Everyx is higher than Philampelus, while from a struc- 

 tural study I have formerly brought Deilephila and Philampelus 

 together. I merely remark here that in reference to recent 

 statements, I do not know Abbot & Smith's Gaum, nor any 

 of the species with angulated wings referred here to Pogocolon. I had 

 only examined and described the two species of Lepisesia, while from 

 figures I should judge Abbot's species belonged to a different genus. 

 While the higher genera of the Choerocampinae have the wings entire, 

 often falcate, the lower have them angulated, and in the genus Ambulyx 

 we have a species with ocellated secondaries. The colors become rich 

 tints of gilded brown and yellow ; roseate hues obtain largely and the 

 spots on the secondaries prepare us for their final expression in Smerin- 

 thus. The ornamentation of the thorax in Snierinthus recalls Philam- 

 pelus, Ambulyx. Although, on general grounds, I would admit that the 

 Bombycid analogies of the Smerinthinse lower them in the rank in the 

 family, I believe the nearest approach to them at present existing is the 

 genus Ambulyx among the Choerocampinae. The frequently pink sec- 

 ondaries in Ambulyx prepare us for the usually pink hind wings in the 

 Smerinthinse. Every indication from color, pattern and shape of wing, 

 favors the idea that the two Groups, Choeeocampinse and Smerinthinae, 

 are related. This is the main point of my arrangement of the imagoes, 

 and I believe the known larvae sustain this view of the relationships 

 within the Family. The real gray colors only obtain as a rule within the 

 Subfamily Sphinginae; the Smerinthinse are gray, tempered with brown 

 shadings and with pink discs to the secondaries, as we see in some other 

 moths, such as the Dryocampas. The most splendidly ornamented Hawk 

 Moths are to be found in the Choerocampinae, radiant in rich golden 

 yellows and oUves, and some Asiatic species are marvels of beauty. The 

 larvae of the Smerinthinae feed by preference on fruit and nut trees. The 

 larvae of the Acherontiinae and Sphinginse on plants belonging to the
