238 THE CANADIAN ENTOMOLOGIST. 



At the time there was a strong southerly breeze blowmg off the water, to 

 which they were fully exposed. They were clinging to lumps of moist sandy 

 mud, which had been recently dredged for filling the crib, and to moistened 

 wood-work. No attempt was made at flight while being picked up. On 

 the inner edge, or land side of the crib, not one was to be seen.

NOTES ON THE LARV^ ON SOME SPHINGID^. 



Dear Sir, — In looking over your Entomological Report for 1881, I 

 find, among the descriptions of the larvae, pupee and images, the follow- 

 ing about the larva oi He mar is tenuis, Gr. : " The larva is, we believe, at 

 present unknown." I have collected and reared this same larva for the 

 last four or five years, and found it plentiful, feeding on the snowberry, 

 Symphoricarpus, of which I have noticed, I believe, two varieties or 

 species : one with small, almost round leaves, the other, which seems very 

 rare, with larger leaves and more pointed. Having believed this larva to 

 be fully described, I took no pains to make notes of its color or character- 

 istics, and could not now furnish a description of it. I have a number of 

 pupae of this species. I also found two sphinx larvae this season, of which 

 I have not yet seen a published description. Being much occupied at 

 the time I was feeding these, I put off making notes until one day when I 

 was at leisure, then I found it was too late, as they had entered the 

 ground. One I took feeding on Privet Ligustrum \ it had the general ap- 

 pearance of Sphinx drupiferarum in size and color, only that the oblique 

 lines were light yellow, almost white, with a broad band nearly an eighth 

 of an inch wide of a beautiful clark ultramarine blue ; caudal horn light 

 bluish-green, ending in a horny brown point, heavily granulated with 

 black. The other larva I found on black ash and on the fringe tree, of 

 which we have several fine specimens in the city park ; on these latter I 

 also found feeding S. c/iersis, which much resembled this one. Chersis 

 differs in that it tapers slightly towards the head ; the stigmata are white 

 in the centre, surrounded with bright red, and the caudal horn is but 

 lightly granulated with black. Pupae without tongue case ; of a coffee- 

 brown color, whilst in the former it is almost black. Both larvae fed 

 readily on black ash in my garden. H. tetiuis I have never found feeding 

 on any other than the above mentioned shrubs. I also found a third 

 larva feeding in company with H. thysbe, much resembling D. myron, on 

 Viburnum detitatum, the pupae of which is a light grayish tan color, with 

 the markings of a Darapsa. Ph. Fischer, 528 High St., Buffalo, N. Y.
