tree, and to the walnut Sphinx (Smerinthus Juylandis), 

 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 (Celtis occidentalis) and the plum-tree ; Sphinx 

 Kctimice inhabits the broad-leaved laurel (Kalmia latifolia) ; 

 the caterpillar of the Grordim is found on the apple-tree ; 

 that of the great ash-colored Sphinx ($. 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 chcerilus and versicolor may be found 

 on swamp pinks (Azalea viscosa and nudiflord). The cater- 

 pillar of the white-lined morning Sphinx (J)dlephila lineata) 

 feeds upon purslane and turnip leaves ; and that of Deile- 

 phila Chamcenerii on the willow-herb (Epilobium angmti- 

 folium). The clear- winged Sphinges, Sesia pelasgm lb (Fig.

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