SPHINX EREMITUS. 



BY THOS. W. FYLES, COWANSVILLE, P. Q. 



This species first came under my notice four years ago. I have met 

 with it every year since, have raised it from the larva, and have taken the 

 perfect insect at Honeysuckle. I find a drawing of 6*. eremitus in No. 13 

 of Strecker's Work on the Lepidoptera, and an account of the larva 

 written by Prof. Snow, of Kansas. The account is as follows : 



" Length 3^ inches, greatest thickness .56 in. Head greenish brown 

 with distinct white stripe on each side ; general color of body pale green, 

 with seven oblique lateral white bands ; caudal horn black and in length 

 .37 in. It becomes full grown from 21st of September to 15th of Octo- 

 ber ; imago appears from May 20th to June 10th. Food plants, Salvia 

 Pitcher i Torrey, and Salvia trichostemmoides Pursh. The larva? were first 

 observed by me in October, 1873, in great abundance, and several 

 imagines were obtained from them in the following May and June. The 

 species is double-brooded.'' 



My own account of the larva is this : 



Discovered in September, 1874, feeding on Salvia officinalis. Sepia- 

 colored — slightly granulated like "shagreen" — having a varnished appear- 

 ance. Anal horn black, rather small. The first segments (i. e., those to 

 which the pro-legs are attached) horn-colored and semi-transparent, having 

 two black shield-shaped blotches upon them, of which the hinder is much larger 

 than the former. Pro-legs black. Transverse side-lines whitish, the hind- 

 most of them broader than any of the others. Spiracles black. Head 

 with two longitudinal whitish lines. 



I have seen, I suppose, thirty of the caterpillars, and this description 

 would answer for any one of them. The difference in the body-color of 

 the insects described by Prof. Snow and that of those described by 

 myself, is no greater, perhaps, than I have met with in the case of indi- 

 viduals of S. quinquemaculata. But I do wonder that I have never come 

 across any " pale green " specimens, and also chat nothing resembling the
