304 Catalogue of North American Sphinges. 



like spots having a red centre and a black margin and connected 

 by a longitudinal white line, on each side of the body, and a red 

 caudal horn. It lives on Spermacocce Hyssopifolia, and, like the 

 other species, is transformed in an imperfect cocoon which it spins 

 above ground. Pupa clay-colored, freckled with dusky spots. It 

 inhabits the Southern States, the West Indies, and South America. 

 I am indebted to Dr. J. E. Holbrook of Charleston, S. C, and 

 to Dr. II. B. Hornbeck, of St. Thomas, W. I., for specimens. 

 The antennas are straight, with a shorter terminal hook than in 

 the three preceding species ; the outer margin of the fore-wings 

 is not so sinuous, and the abdomen is much more elongated, slen- 

 der and pointed. It may be necessary, hereafter, to institute a 

 new genus for the reception of this and several other closely al- 

 lied West-Indicin and South-American species. 



Genus VI. Deilephila. Ochsenheimer. 

 1. D. lineata. F. = Daucus. Cramer. 



Olive-brown ; fore-wings with a pale buff-colored stripe from 

 the base of the inner margin to the lip, crossed by six white lines 

 on the nervures, tiie outer margin ash-gray, the fringe and edge 

 of the imier margin white ; hind-wings rose-pink, with a white 

 spot near the inner margin, a black band at base, another near the 

 hind-margin, and the fringe, white ; a white line on each side of 

 the head above the eyes, and six lines, of the same color, placed in 

 pairs, on tlie thorax ; two rows of small black spots and a slender 

 dorsal white line on the top of the abdomen, the sides reddish, 

 with a short transverse black band on each side of the first ab- 

 dominal segment, and a white band behind it, followed by a lat- 

 eral series of alternately black and white spots. Expands from 

 three to four inches. Larva pea-green, with a longitudinal series 

 of nine or ten orange-colored oval spots encircled with black, on 

 each side, and an orange-colored caudal horn. Feeds upon the 

 leaves of the purslane and turnip, and of various other humble • 

 plants, and buries itself in the ground to undergo its transforma- 

 tions. Pupa light brown. 



Contrary to what is usual among our Sphinges, there are two 

 broods of this species in the course of one summer. This is the 

 true Sphinx lineata of Fabricius, described by hmi as an Am^eri- 

 can insect in his " Systema Entomologia;." His description of 

 the thorax, " striis tribus albis duplicalis," apjAics exactly to our 

 insect, and not to the Livornica of Europe, with which it is often
