Sphinx chersis, Grote and Robinson. 
General color pea-green, with a bluish head marked by two pale 
bands. There are seven bright yellow oblique bands on each side, 
edged above with blue. The seventh line is continued on the 
eleventh segment to the base of the horn. The horn is of medium 
size, curved downward at the tip, of a pale blue color, marked with 
blue points above. Anal plate triangular, raised and dotted with 
elevated black points. True legs bluish; black at the tips; pro-legs 
green with blackish tips. 
Stomata, orange colored. Length, two to three inches. Food 
plant, the Lilac (. Syringa vulgaris). 
Sphinx coniferarum, Sm. and Abb. 
Dr. Fitch describes this larva as “eating the leaves of pine and 
other evergreens; a large cylindrical worm checkered with brown 
and white spots; with a whitish line along the middle of the back, 
and a short horn on its hind part.” 
According to the figures of Smith and Abbott, and the statement 
of Guenee, it is without the horn on the eleventh segment. 
Ordinarily it is of a bright green, with a white dorsal stripe 
bordered with rosaceous; along the lower border of the side there 
is a yellow stripe, between which and the dorsal band there is 
another yellow stripe. Head yellow, with dark rays. Stomata en¬ 
circled with black. 
In the work of Smith it is described as having the same form 
but grayish in color, with two lateral bands almost white alter¬ 
nating with black. 
It is found on Pinus palustris and probably on other species of 
pines. 
Sphinx harrisii, Clem. 
The larva is green, furnished with a dorsal ray of reddish-brown 
which is slightly arrested posteriorly. There is, on each side, a 
yellow stripe and a substigmatal white stripe. The thoracic feet 
are rosaceous, and there is a ventral stripe of the same color. It is 
found in September feeding on the White Pine ( Pinus strobus). 
Sphinx pineum, Lintner. 
The larva of this species is similar to that of S. harrisii , and 
feeds on the leaves of the same tree ( Pinus strobus). 
Lethia gcrdius, Hubn. 
Very similar to S. drupiferarum. It feeds on the leaves of the 
Apple.
