314 Catalogue of North Amejican Sphinges. 



which in the fore-wings is nearly oval and slightly narrowed in 

 the middle, in the hind-wings larger, kidney-shaped and almost 

 divided in two ; palpi beneath, a spot before the anterior coxas, 

 the tips of the tarsal joints above, and the hind-edges of the last 

 three or four abdominal segments white. Expands from six to 

 eight lines. 



This species comes very near to the fenestrata of Europe, but 

 is sufficiently distinct from it. 



Mr. Doubleday has presented to me a much larger species of 

 Thyris, which was captured by him in Florida, and was new to 

 my collection. There is a figure of it in M. Boisduval's Hist. 

 Nat. Ins. Lepidopt. Vol. I, pi. 14, where it is named T. luguhris. 

 This name has not yet received the proper sanction of a descrip- 

 tion ; but, taking into consideration the circumstances under 

 which this nondescript came into my possession, I do not think 

 proper to describe it myself at this time.

Black ; with two sulphur-yellow spots on the fore-wings, and 

 two white ones on the hind-wings; shoulder-covers and front 

 sulphur-yellow ; first and second pairs of tibiae thickly covered 

 with orange-colored hairs. Expands from eleven to fifteen lines. 

 Larva, as represented by Abbot, (Ins. Georg. p. 8, pi. 44,) cylin- 

 drical, elongated ; yellow, with transverse rows of black points, 

 slightly hairy, and without a caudal horn. It lives on the grape- 

 vine, and encloses itself in a cocoon in the earth. 



In some individuals there is a white spot near the end of the 

 abdomen, and the inner white spots of the hind-wings are en- 

 larged and cover the wholf base of the wings. Mr. Kirby (Fauna 

 Bor. Amer. IV, p. 301, pi. 4, fig. 5,) has described another species 

 of Alypia, a native of Nova Scotia and Canada, and names it A. 

 MacCullochii.
