tree, and to the walnut Sphinx QSmerintlius Juglandis), 

 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 ; Spiliinx 

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

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

 that of the great ash-colored Sphinx (#. cinerea) on the 

 lilac ; Hylceus on the black alder QPrinos glaber, &e.) 

 and whortleberry ; and the curiously checkered caterpillar 

 of Sphinx conifer arum on pines. Of the hog-caterpillars, 

 those of Clioerocampa choerilus and versicolor may be found 

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

 pillar of the white-lined morning Sphinx {Deilephila lineata) 

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

 pliila Chamamerii on the willow-herb (Epilohinm angusti- 

 foliuni). The clear- winged Sphinges, Sesia pelasgus 1 ' (Fig. 

 156) and diffinis, are distinguished by their transparent 

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