296 Catalogue of North American Sphinges. 
Ligustri. 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 buried, 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. Expands 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. S. Hyleus. Drury.=Prini. 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 nat- 
row indented brown band across the middle, and a broad one on 
the outer margin ; fringes spotted with white; a whitish line 
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 pet 
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 Prinos glaber 
and various species of Vaccinium, 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. Plebeja. 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, spotte 
with dark brown; abdomen with three black lines, one do : 
and two on each side, the latter enclosing a longitudinal series ° 
“es white spots. Expands three inches. Inhabits the Souther
