Genus COCYTIUS Hubner 



The genus Cocytius, which includes some of the largest 

 hawkmoths which are known, contains five species, all of which 

 are found in the tropics of the new world. They may easily be 

 recognized by the fact that the third joint of the labial palpi is in 

 both sexes prolonged into a small, sharp, conical, naked horn. 

 The larvae, which feed upon the Anonacece, are covered with fine 

 hairs. Only one of the species is found within the faunal limits 

 covered by the present work. It occurs in southern Florida, and 

 in southern Texas as a straggler.

 Giant Sphinx.)

The species is somewhat variable, specimens from the 

 Antilles being often lighter in color than those from Central 

 America, and the continental portions of its habitat. This lighter 

 form is accepted by Rothschild & Jordan as typical, and the 

 darker form is called by them Cocytius antceus medor Stoll. The 

 difference is hardly sufficiently constant to justify the separation 

 into two subspecies. The insect ranges from Florida into 

 southern Brazil. 



Genus PROTOPARCE Burmeister 



The head is prominent. The body is stout and heavy. The 

 tongue in both sexes is at least as long as the body. The palpi 

 are large, ascending, and appressed to the front, having the 

 basal joint long, the second a little shorter, but broader, and 

 the terminal joint minute. The eyes are large, feebly lashed. 

 The tibiae are either without spines, or feebly armed with 

 minute spinules. The mid tarsus is provided with a comb of 

 long bristles. The venation of the wings is typically spongi- 

 form. The outer margins of the primaries are evenly rounded. 

 There is a slight proiection of the secondaries at the extremity 

 of vein i b. The prevalent colors of the wings are shades of 

 gray, banded and mottled with darker and lighter lines and
