296 Catalogtte of North American Sphinges. 



Ligiistn. The present species is remarkable for the length and 

 sharpness of the wings, which are of a fine neutral gray tint, and 

 for the prominence of the head and palpi. 



* * Tongue-case of the pupa not detached, but hiried, and sol- 

 dered to the breast. 



7. S. sordida. H. 



Dark gray ; fore-wings variegated with dark brown, dashed 

 with a few blackish lines, and with a whitish dot near the mid- 

 dle ; hind-wings with a blackish basal spot, and two broad black 

 bands ; a dark brown line on each shoulder-cover ; abdomen with 

 a dorsal black line, and alternate black and light gray bands on 

 the sides. Exppinds two inches and three quarters. 



Although the" larva and pupa of this species are unknown to 

 me, I judge from analogy that it belongs to this division of the 

 genus Sphinx. 



8. iS. Hylmts. Drury. =Pmu. Smith-Abbot. 



Rusty brown ; fore-wings mottled with white, banded with 

 jagged dark brown lines, with a white dot near the middle, and 

 a spot of the same color at tip ; hind-wings whitish with a nar- 

 row indented brown band across the middle, and a broad one on 

 •the outer margin ; fringes spotted with white ; a whitish hue 

 above the eyes extending on each side of the thorax ; two lon- 

 gitudinal rows of white dots on the top of the abdomen, and a 

 series of short narrow white bands on each side. Expands two 

 and a quarter to two inches and three quarters. Larva pea- 

 green, with six or seven oblique lateral whitish bands edged 

 above with pink, a purple caudal horn, and a pale blue line on 

 each side of the head. It feeds on the leaves of Priiios glaber 

 and various species of Vacdniwm, and enters the earth to be 

 transformed. 



This insect is much like the Brontes of Drury, which, how- 

 ever, is a much larger species, more distinctly banded with 

 white, &c. 



9. S. Plcbeja. F. 



Gray ; fore-wings with a white dot near the middle, and five 

 or six short oblique blackish lines between the nervures ; hind- 

 wings sooty black, dirty white at base ; fringes white, spotted 

 with dark brown ; abdomen with three black lines, one dorsal, 

 and two on each side, the latter enclosing a longitudinal series of 

 dirty white spots. Expands three inches. Inhabits the Southern 

 States.
