common enough to prove seriously injurious. The same 

 observation will apply to that of the chocolate brown-eyed 

 Sphinx (^Smerinthus mi/ops'), which hves on the wild-cherry- 



tree, and to the walnut Sphinx (^Smerinthus 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 ; Sphinx 

 Kalmice inhabits the broad-leaved laurel (^Kalmia latifolia) ; 

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

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

 lilac ; Hylceus on the black alder (^Prinos glaher, &c.) 

 and whortleberry ; and the curiously checkered caterpillar 

 of Sphinx coniferarum on pines. Of the hog-caterpillars, 

 those of Cfhoeroeampa choerilm and versicolor may be found 

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

 pillar of the white-lined morning Sphinx (^Ddlephila lineata) 

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

 phila Ohamcenerii on the willow-herb (^JEpiloMum angusti- 

 folium). The clear- winged Sphinges, Sesia pelasgus'^^ (Fig- 

 156) and diffinis, are distinguished by their transparent 

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