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 Auonacece, 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.

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 sphingi- 
form. The outer margins of the primaries are evenly rounded. 
There is a slight protection 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
