272 LEPIDOPTERA. 



Mr. Saunders writes me that he has found it feeding on the 

 pine, about the middle of September. "It is two inches long, 

 the body being smootli and nearly C3dindrical and thickest in 

 the middle of the body. The head is large, pointed aboA'e, flat 

 in front and green, with a j-ellow stripe on each side. The 

 body is bright green, with a dorsal row of dark red spots on 

 the fifth to the twelfth segments inclusive, with a bright yel- 

 low stripe on each side of the reddish spots and a lateral 

 white stripe mixed with yellow." Tlie moth is a very small, 

 ash grey species, only expanding two inches. It frequents 

 flowers at dusk in June. 



The genus S2Mnx, as now limited by systematists, is much 

 larger bodied, Avith a long and narrow head, small eyes and 

 long and narrow Avings. The head of the larva is rather 

 large, semi-oval and flattened in front. The body is cylin- 

 drical, smooth and obliquel}'^ banded on the side, Avith an 

 arching, caudal horn. It transforms in a subterranean earthen 

 cell. The tongue-case of the pupa is short and free, instead 

 of being soldered to the body. Sphinx gordius Cramer is dark 

 broAvn, Avith a roseate tinge, and the thorax is blackish broAvn 

 above. The larva feeds on tlie apple. 



Sphinx Jcalmice Smith is hoary and rust-red, and on the hind 

 wings are a median and marginal black band. The caterpillar 

 feeds on the lilac and laurel. It is pale green, with scA^en 

 oblique, lateral, pale j'cIIoav bands, edged above with black, 

 which is again bordered Avith pale blue. Sphinx drupiferarum 

 Smith has the fore-wings blackish brown, with the discal dot 

 and outer edge of the Aving Avhitish faAvn-color. The larva 

 feeds on the different species of plum. The body is pale green, 

 with lateral purple bands, edged beneath with white. Sphinx 

 chersis Hiibner (S. cinerea Harris) is the largest species Ave 

 have, and is pale ashen, and reddish gray beneath. The larva 

 feeds on the lilac. 



The large " potato Avorm " belongs to the genn9. Macrosila, 

 containing our largest species of the family ; the head is pro- 

 portionally large, and the Avings are rather broad, with the 

 interior angles dilated. 31. cingulata Fabr. has pink hind 

 Avings and pink spots on the abdomen. It feeds on the sAveet 

 potato. M. qxiinque-maculata Haworth (Fig. 199, moth ; a,
