Sphinx oreodaphne. Hy. Edw. (Proc. Cal. Acad. Sci., July, 1873.) 
My friend Mr. H. Strecker, of Reading, Pa., has suggested to me that this 
may be only a small form of Sph. chersis, Hbn., and certainly there is a great 
resemblance, excepting in point of size, the largest specimen of Oreodaphne 
I have seen measuring only 37% inches in expanse, the smallest 234 inches, 
while the average size of Chersis is 4% inches. The markings, also, even in 
the most perfect specimens, are much less pronounced than those of Chersis, 
and the general color of the insect is much paler. If, however, Mr. Strecker’s 
conjecture be correct, the synonymy will have to be 
Sphinw chersis. Hbn. 
Var. Oreodaphne. Hy. Edw. 
Sphinx perelegans. Hy. Edw. (Proc. Cal. Acad. Sci., July, 1873.) 
Iam inclined to think that this and the following species are only two of 
others which will yet be found in California, having an affinity with Sp. 
gordius and Sp. eremitus of the Atlantic States. The only specimen of this 
species was taken by the late G. R. Crotch, at Gilroy, Santa Clara county, 
and is in my collection. 
Sphinx Vancouverensis. Hy. Edw. (Proc. Cal. Acad. Sci., July, 1873.) 
Since describing this species, I have had the good fortune to procure two 
other specimens, one from Portland, Oregon, and the other from the Big Trees 
of Calaveras county. They are so strongly marked as to put to flight any 
doubts I may have entertained as to the genuineness of the species. 
Hyloicus Sequoice. Bdv. 
I am only acquainted with one specimen of this very rare species, taken by 
myself in Bear Valley, Placer county, and noticed in Proc. Cal. Acad. Sci., 
July, 1873. 
Hyloicus Strobi. Bdv. 
Dr. Boisduval is himself in doubt as to the locality of this species, and 
without a careful examination of the type it is difficult to say whether it be 
Californian or not.
