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 drupifcrarum inhabits the 
hackberry ( Celtis occidentalism 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 ; Hylceus 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 Chcerocampa chccrilus and versicolor may be found 
on swamp pinks (Azalea viscosa and nudiflora). The cater- 
pillar of the white-lined morning Sphinx (Deileplnla lincata ) 
feeds upon purslane and turnip leaves ; and that of Deile- 
phila Charncenerii on the willow-herb (Epilobium angusti-

wings and their fan-shaped tails. They hover over flowers,
