common enough to prove seriously injurious. The same 
observation will apply to that of the chocolate brown-eyed 
Sphinx (^Smerinthus mij 02 :)s')^ Avhich lives on the wild-cherry- 
tree, and to the walnut Sphinx (^Smerinthus Jiiglandis')^ 
which lives on the black walnut and butternut. The latter 
species is destitute of eye-like spots on the hind wings. 
Of those belonging to the genus Sphinx proper, that 
which bears the specific name drupiferarum inhabits the 
hackberry (^Oeltis occidentalis) and the plum-tree ; Sphinx 
Kalmice inhabits the broad-leaved laurel (^Kalmia latifolia) ; 
the caterpillar of the Gordius is found on the apple-tree; 
that of the great ash-colored Sphinx (^S. cinerea) on the 
lilac ; Hglceus on the black alder (^Prinos glaber^ &c.) 
and whortleberry; and the curiously checkered caterpillar 
of Sphinx coniferarum on pines. Of the hog-caterpillars, 
those of Choerocampa choerilus and versicolor may be found 
on swamp pinks (^Azalea viscosa and nudiflora). The cater¬ 
pillar of the white-lined morning Sphinx (^Deilephila lineatd) 
feeds upon purslane and turnip leaves ; and that of Deile- 
phila Chamcenerii on the willow-herb (^Epilohium angusti- 
foliuni). The clear-winged Sphinges, Sesia pelasgus^^ (Fig. 
156) and difjinis^ are distinguished by their transparent 
wings and their fan-shaped tails. They hover over flowers,
