brilliantly colored Choerocampinae inhabiting the Himalayan 

 region. The Choerocampinae are, also, the swiftest fliers and 

 widest wanderers, with their pointed bodies and beautifully 

 curved, sharply outlined wings. As Europe is visited by the 

 celebrated Oleander Hawk and Deihplrila ceJerio, which come 

 from Africa, so we receive from the West Indies the visits 

 of the Blue and Green Hawk, Argons, and the Wandering 

 Bee Hawks, Aellopos, those '-Mother Gary's Chickens" among 

 the Moths. In North America the Smerintliinae are repre- 

 sented by several beautiful species belonging to the more 

 typical, ocellated group ; both Galasymbolus and Paouias are 

 exceedingly richly colored and here the advantage is with 

 the American, when compared with the foreign species be- 

 longing to this northern group. As a survivor of a former 

 Arctic fauna, we have, in California, a Smerinthns related 

 to the European oceUatus. But the less typical genera of 

 the group, with unocellated secondaries, are feebly represented 

 with us; of our two genera and species Cressonia jngJandis 

 is the only peculiar American form. In the SpJiii/t/h/ac the 

 series of genera are more peculiarly American; the number 

 of gray and blackish species recalling the Noctnidae in ap- 

 pearance is noticeable. In Europe, the numerous species 

 of Deilephila are the remarkable features of the fauna; we 

 have only two, both borrowed from thence, survivors of an 

 extinct boreal representation of the family. 



In the present work I mention the species inhabiting 

 the Middle States, having in particular the State of New 

 York under consideration, where most of my studies (either 

 at Buffalo or the country about the City of New York) were 

 conducted. As to the Florida Colony of tropical species, 

 or the West Coast fauna of which I know but little, an 

 account is given in other papers, the species being enume- 

 rated in my list above alluded to. My only synonym in 

 this Family (and it might be well if my critics could show 

 so clean a record) is Lepisesia victoriae from California, which 

 is said to be Boisduval's Pferogon Clarkiae, a species I do 

 not know. But my description was excusable since I was 

 led to expect a species with angulated wings and resembling
