Sphingidae 
The larva of this hawkmoth has a long thread-like anal horn. 
It is very strikingly colored, the body being purplish black, 
girdled with yellow rings between the segments, and the head 
and anal claspers being bright red, of the coior of sealing wax. 
It feeds upon various Euphorbiaceous plants, preferably Plum¬ 
eria. The insect occurs not uncommonly in southern Florida. 
Genus ERINNYIS Hubner 
This is a moderately large genus, the species of which are all 
confined to the tropical or subtropical regions of the Western 
Hemisphere, though one species, as we shall see, occasionally 
occurs as a straggler far north of the metropolis of the genus.

Sphinx.) 
Syn. flavicans Goeze; jasciata Swainson; edwardsi Butler. 
The caterpillar is brown on the upper side, and pale green on 
the lower side, the colors being separated by a dark brown inter¬ 
rupted lateral band on either side of the body. On the third 
segment from the head there is a dark spot relieved by a red Ting 
in the centre. The anal horn is quite short. The larva feeds 
upon Jatropha and Carica. The insect occurs in southern 
Florida and ranges southward as far as northern Argentina.

This hawkmoth, which is widely distributed through the 
tropics of the new world, displays considerable variation, and 
several forms, or local races, have been recognized. The one 
which occurs within our territory we have figured, and the 
student will have no difficulty in recognizing it. The larva, 
which is said to closely resemble that of the next species, is 
reported to feed upon Morrenia in the West Indies. It occurs in 
Florida.

This is quite the commonest of all the hawkmoths of the 
American tropics, and becomes a perfect drug in collec¬ 
tions made by amateur naturalists, who venture into those
