The omission from' the fii^ure of an angle in tlie margin of the 

 posterior wings at the submeclian nervure, must, we think, be an 

 error in representation, ac also the termination of the anal process of 

 the black spot, not in the anal angle, but wholly within the internal 

 niargin. Ei'rors bo obvious and other probable ones, must necessarily 

 afford a poor basis on wliich to sustain a valid species. 



Mr. Grote, in liis valuable papers on American Sphingidi^e, has 

 advocated the specific distinctness of 6^6/"i6'y^*.''^ In one of them he 

 remarks : " The fact that CerUii Kirby, is certainly distinct from 

 aS'. genilnatus Say, an opinion I have entertained since studying 

 Xirby's description and iignre, has been recently ascertained by the 

 discovery of specimens, as I am informed by Mr. S. Calverley.'' At 

 the present I have no means of determining the character of the 

 specimens referred to, but I cannot believe that they will prove 

 to be different from the exceptional form obtained by me from the 

 deposit of A', gem'matus eggs above recorded. 



Mr. W. H. Edwards informs me that he has regarded S. Cerlsyi 

 as a distinct form. He has, in his collection, a specimen taken far 

 north, by Ivennicott, believed to be the only one in the conntry. 



Kirby's type is probably in the collections of the British Museum, 

 where, it is stated, the insects described in Fauna JBoreali-Americana 

 were deposited. 



From the \ery brief description of S. oj)thal7nicu.s given by 

 Boisdnval,t it was thought by Clemens to be possibly a variety of 

 aS'. gem.inatus, having but a single eye in the ocellated spot. X Grote 

 and Robinson in their catalogue of ]N". A. Sphingidse, have recorded 

 it as a distinct species. § 



Through the kindness of Mr. James Angus of West Farms, N. Y., 

 I have had the privilege of examining a beautiful specimen of the 

 species, received by him from California. It is structurally distinct 

 from S. geiiiinatus^ and is closely allied to -6'. ocellatus of Europe, from 

 which however it differs materially. 



As near as I could determine without dissection, the antennge 

 consist of about forty joints having longitudinally on them a single 

 series of thin, nearly square laminee, each equal in length to the joint
