Sphingidae 



(2) Ceratomia undulosa Walker, Plate VI, Fig. 7, ? . (The 

 Waved Sphinx.) 



Syn. repentinus Clemens; brontes Boisduval (non Drury). 



This hawkmoth, which may easily be separated from its 

 congeners by its lighter color and the distinct wavy maculation 

 of the fore wings, lives in the larval stage upon the ash and the 

 privet. It ranges from Maine and Canada to the Carolinas and 

 westward into the trans-Mississippi region east of the great plains. 



(3) Ceratomia catalpae Boisduval, Plate IV, Fig. 7, $ . 

 (The Catalpa Sphinx.) 



The larva feeds upon various species of catalpa, and has in 

 recent years been charged with doing considerable damage to 

 these trees by denuding them of their foliage. The insect ranges 

 from New Jersey and southern Pennsylvania southward to 

 Florida and westward through the Mississippi Valley, wherever 

 its food-plant occurs. 



Genus ISOPARCE Rothschild & Jordan 



Tongue short and weak. Palpi small. Tibiae without spines. 

 The first protarsal segment is short. Hind tibia armed with long 

 spurs. Comb on mid tarsus wanting ; pulvillus wanting. 

 Paronychium without lobes. Veins 6 and 7 of the hind wing on 

 a long stalk. 



(1) Isoparce cupressi Boisduval. 

 (The Cypress Sphinx.) 



The insect is of an almost uniform 

 brown color on the upper surface of 

 the wings, and may be distinguished 

 from other species by the two con- 

 spicuous parallel dark markings on 

 the limbal area of the fore wings. It 

 is extremely rare in collections, only Fig. 23. Isoparce cupressi 

 three or four specimens being as yet Boisduval. 



known. It has been reported from Georgia and Florida.
