162 THE CANADIAN ENTOMOLOGIST. 



" red marginal lunules." The fore wings are also very evidently different 

 in tint and color of median spots, while from my recollection of Mr. 

 Walker's type, it was much nearer C. unijuga than the present species 

 seems to be. 



Note 2. — In looking over my paper on this genus, in the Transactions 

 of the American Entomological Society, I find that I have stated in refer- 

 ence to C. nebulosa, that " Mr. Edwards compares the secondaries of this 

 species quite wrongly with C. cerogama." In reality, Mr. Edwards no- 

 where directly alludes to C. cerogama. I should have written that Mr. 

 Edwards describes the secondaries in such a manner as to lead one to 

 suppose that he intended a species resembling C. cerogama, and my idea 

 is correctly expressed in my original description of C. fionderosa. I am 

 sorry that in repeating my idea from memory, without referring to former 

 papers, I should have used words not in literal accordance with the 

 facts. 



Note 3. — The median band of the hind wings in C. fiarta is curved, 

 and occasionally a few dark scales are visible along the cross vein above. 

 Darker specimens of C. fiarta, exhibiting every peculiarity of the species, 

 the apical streak, characters of the hind wings, etc., have occurred about 

 Buffalo with the paler, more usual specimens, and seem to be Mr. Strecker's 

 " nov. ? var." perplexa ; it seems to me that an assumption of bastardy is 

 unnecessary to account for so slight a variation. Mr. Strecker's statement 

 that M. Guenee mistook C. relicta for C. fraxini must be based on an 

 erroneous comprehension of my quotation of that author. So excellent 

 an Entomologist as M. Guenee could not have made such an error. 

 Fraxini was doubtless sent him with an erroneous locality. M. Guenee 

 always shows an appreciation of the slightest differences in separating 

 European and American specimens throughout his great work, and here 

 the difference is excessive. Occasionally we see Acherontia atropos incor- 

 rectly referred to as occurring in America, nor can in this case any of our 

 Sphingidse have been mistaken for it. Mr. Strecker criticises the coloring 

 of subnata; this plate was published plain and drawn without being 

 intended for coloring ; the few copies colored for private distribution are 

 not properly the subject of public criticism. Mr. Strecker's figures, 

 however, are, and the coloring of the hind wings of antinynpha, fig. 7, and 

 unijuga, fig. 9, is so bad that I should doubt his determinations were it 

 not that he has taken his information from the collection of the American 

 Entomological Society, which represents my identifications.
