Sphingidse 
Genus EPISTOR Boisduval 
Five species belong to this genus, the type of which is the 
species which we figure, and the only representative of the 
genus found in our territory. 
(i) Epistor lugubris Linnaeus, Plate II, Fig. 17, $. (The 
Mourning Sphinx.) 
Syn. fegeus Cramer; luctuosus Boisduval. 
There can be no difficulty in identifying this well-marked 
but obscurely colored hawkmoth, which occurs in Florida and 
Georgia, and even straggles now and then as far north as New 
Jersey. It is very common in the Antilles and South America. 
In Florida it is double-brooded, appearing on the wing in May 
and September. The larva feeds on the Vitacece. 
Genus CAUTETHIA Grote 
There are three species of this genus, only one of which 
occurs within the limits of the United States. The figure we 
give will permit of its identification without difficulty. 
(1) Cautethia grotei Henry Edwards, Plate II, Fig. 21, $. 
(Grote’s Sphinx.) 
The habitat of this species is southern Florida, where it 
apparently is not uncommon. 
Genus SESIA Fabricius 
The body is depressed, fusiform, without lateral tufts, but 
with a broad fan-shaped anal tuft, composed of coarse flattened 
scales. The abdomen is produced for more than half its length 
beyond the hind wings. The palpi are produced and appressed, 
forming a short snout-like projection beyond the head. The 
tongue is stout, but comparatively short. The antennae are 
slightly thickened at the end, and have a sharp recurved tip. 
The mid tibiae have terminal spurs, and the hind tibiae two pairs 
of spurs. The fore wings have eleven veins. The venation is 
characteristically sphingiform, and is illustrated in Figure 21. 
The prevalent colors are black and dark brown with white spots 
and bands on the wings and in some species on the abdomen. 
The moths fly in the hottest sunshine. 
The type of the genus Sesia established by Fabricius is the 
species named tantalus by Linne. Rothschild & Jordan, in the 
61
