196 Remarks on the Sphingidce of Ciiba. 



have much pleasure in receiving a letter from Mr. John Gund- 

 lach, from which I learn, that the new species of Erinnyis, 

 which I described in the paper already alluded to, are partly 

 those which Dr. Herrich-SchEeffer had been unable to identify 

 as having been already described. Thus, the species described 

 under u No. 7," and of which Dr. Herrich-Sclueffer remaifc : — 

 "Eine neue Art, welche ich auch von H. Kaclen aus Mexico 

 erhielt" — is the species which I also Jiave regarded as new and 

 described as Erinnyis meriance Grote. My determinations of 

 K ello, E. alope, E caicus, and E.guttularis, accord with those 

 of Dr. Herrich-Schasffer, while E. rimosa Grote is the species, 

 as I have stated, that Dr. Herrich-Schasffer doubtfully regards 

 as intended by Cramer under the specific name of " scyronP I 

 describe here an allied species which perhaps equally resem- 

 bles the figure of the Dutch entomologist, and I remain of the 

 opinion, that the coarseness of the illustration will lead to the 

 entire rejection of the specific name used by Cramer, since I 

 can with difficulty believe that a u Sphinx" will be discovered, 

 that can be referred with certainty to the " Sphinx scyron" of 

 this author. Mr. Gundlach also assures me that the individual 

 1 have regarded as the female of E. melancholica Grote, is a 

 distinct species, of which I now receive a second female indi- 

 vidual, and that it is of this species, which I describe here as 

 Erinnyis cinerosa, that Dr. Herrich-Schaeffer speaks, in his 

 remarks under E. amotrus, Cr. sp. Corr. Blatt, p. 59 (23), 1865. 

 E. melancholica Grote, is not mentioned by Dr. Herrich- 

 Schseffer ; this species, of which I have only the male, differs 

 from E. cenotrus (of which I have both sexes), in the absence 

 of the well defined costal paler patch on the upper surface of 

 the primaries, and the differently shaped secondaries. I can 

 in no event regard it as a variety of E. cenotrus, a species nearly 

 allied to E. meriance, in the ornamentation of the primaries, 

 which latter is otherwise abundantly distinct from either. 



Dr. Herrich-SchEeffer, speaking of Enyo lugubris, Linn, sp., 

 says: — "Ich finde die als camertus, Cr. einjresendeten Exem-
