Sphingidae 



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. 



(i) 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
