From the colors and banded abdomen, I follow these insects 

 with the final subfamily Acherontinae, not found in North 

 America. 



Kilo. Linn. "The Wandering Hawk." Light gray, 

 the female darker, hind wings russet, abdomen banded with 

 black. Breeds in the extreme South, West Indies and Mexico. 

 A wanderer in the North, which it reaches in the Fall. 



Remarks. 



As I have elsewhere pointed out the Macroglossians 

 with angulated wings form a subgroup, leading to the Choero- 

 campians. The typical subfamity contains Hemaris, Aellopos, 

 Lepisesia, Macroglossa and allies, with even wings. My 

 classification is based on natural characters, and no scientific 

 reasons have been brought forward by any dissident. It has 

 been said that a certain class of minds differ mainly to 

 differ and, in the arrangement of such delicate animals, the 

 range of untrained opinion has been found to be wide. 



Considering, as I do, that the Sphingidae may have 

 been evolved from the ancestors of the Ceratocampinae, I 

 regard the subterraneous pupation, without silk, as a low 

 or derivative character, together with the crepuscular or 

 nocturnal flight. On the other hand the surface pupation, 

 the use of silken threads, the diurnal flight, as an approach 

 to the Hesperidae. The surface pupation of tropical SpMnginae 

 must be studied in connection with terrestrial conditions. 

 There is a slight resemblance in the larvae between the 

 Papilioninae and Choerocampinae. 



The generally smooth larvae show exceptionally thoracic 

 crests, as in Triptogon and Ceratomia, genera accordingly 

 related; and this would be a retained character, recalling 

 Eades imperialis. The rough, shagreened skin of the Eyed 

 Hawks in also probably a modified survival. The proofs 

 that the passage to the Splimgidae has been through what 

 we now regard as older forms of Bombyces, are thus many 

 and, if we place this family at the head of the Moths, it 

 is not that it has real affinities with Castnia, which has 

 probably a different immediate origin.
