Catalogue of North American Sphinges. 293 



I have never seen but one specimen, which was much rabbed 



before it came into my possession. It is a female, with a very 



thiclc and robust body, and simple antennsE, and probably is the 



North American representative of S. Tilice and Qwercus.

Genus II. Ceratomia. H. 



I have been induced to propose a new genus for the reception 

 of a single species, presenting characters, in the larva and winged 

 state, which do not allow it to be included in the genus Sphinx 

 as now received. The larva of this species, in the possession of 

 horns on the fore-part of the body, exhibits a peculiarity which 

 hitherto appears to have been unnoticed or undescribed among 

 the Sphinges. The name of the genus, derived from niqaia, 

 fiorns, and &/tin, the shoulder, alludes to this peculiarity. An 

 analogous and still more imposing form is found in the larvae of 

 the PhalcriKP, belonging to the genus Ceratocampa. 

 C. quadricornis. H. ' . ? j' ', 



Light brown ; fore-wings with zigzag and wavy brown and 

 whitish bands, dusky in the middle to the inner margin, the an- 

 terior edge M'hitish, and a large white dot near the middle ; hind- 

 wings with three dusky transverse bands, and a broad blackish 

 hind-border ; fringes dotted with white ; head and a broad line 

 on each side of the thorax to the shoulders white ; shoulder- 

 covers with three and abdomen with five longitudinal brown 

 lines. Expands four and a half to nearly five inches. Larva 

 pale blue-green, longitudinally wrinkled, with a pair of short 

 denticulated horns on the second segment, a similar pair on the 

 third, two parallel series of little teeth on the first four segments, 

 a dorsal row of larger teeth extending to the tail, a long bluish 

 caudal horn, and seven narrow oblique white lines on each side 

 of the body. It feeds upon the leaves of Ulmus A?nericana, 

 and transforms in the earth. 



Genus III. Sphinx. L. 



* Tongue-case of the pupa detached from the breast. 

 1. S. dngulata. F, = Convolvuli. Smith-Abbot. 



Dark ash-gray, variegated with brown, body beneath white ; 

 middle of the hind-wings pink, with three or four black bands ; 

 fringes of the wings spotted with white ; and five pink-colored 

 spots separated by short transverse black lines on each side of
