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 color 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; fasciata 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 ring 

 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. 



(2) Erinnyis lassauxi Boisduval.

Syn. janiphcB Boisduval. 



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
