Catalogue of North American Sphinges. 297 



The only specimen which I have seen was taken by Prof, 

 Hentz in North Carohna, and now belongs to the Boston Soci- 

 ety of Natural History.

Gray ; fore-wings with about three narrow and indented 

 brownish bands, a spot near the middle, one or two streaks be- 

 yond the middle, and the nervures near the outer margin brown ; 

 hind-wings dusky or blackish gradually fading into gray towards 

 the base ; fringes spotted with brown and white; abdomen gray 

 with brownish incisures. Expands one inch and three quarters 

 to two inches and three quarters. Larva^ as figured by Abbot, 

 (Ins, Georg. p. 83, pi. 42,) chequered with brown and white spots, 

 with a dorsal whitish line, and a short caudal horn. It eats the 

 leaves of various kinds of pine, and enters the earth to transform. 

 Mr. Leonard informs me that the tongue-case of the Pupa is 

 short, and buried so as not to rise above the leg-cases. 



For my specimen I am indebted to the Rev. L. W. Leonard, 

 who raised it from a larva found on the pine in Burlington, Vt. 

 In the cabinet of the Boston Society of Natural History there is 

 a larger specimen, which was taken in North Carolina by Prof. 

 Hentz ; the bands on the wings in the latter are less distinct than 

 in my specimen. 



11. S. Ello. L. 



Gray ; fore-wings slightly indented on the outer margin, with 

 a few irregularly scattered black dots, and a blackish stripe ex- 

 tending from the base to the tip; hind-wings rust-red, with a 

 broad black hind-border; thorax with five longitudinal black 

 lines, and abdomen on each side banded with black. In the fe- 

 male the blackish stripe on the fore-wings and the lines on the 

 thorax are usually wanting or indistinct. Expands three and a 

 quarter to four inches. Inhabits the Southern States, the West 

 Indies, and South America. 



In the cabinet of the Boston Society of Natural History there 

 is a specimen of this tropical insect, which was captured by Prof. 

 Hentz in the interior of North Carolina, where eventually the spe- 

 cies may become common. According to Madam Merian (In- 

 sectes de Surinam, page and plate 61) the larva, in Surinam, 

 lives on the leaves of a species of Psidiiim or Guava, is of an ob- 

 scure brown color, with a black dorsal line, some small irregular 

 white spots on the sides, and the head and caudal horn purple.
