THE CANADIAN ENTOMOLOGIST. 131 



Mr. Butler has shown himself to be equally possessed. It is not my 

 intention at this time to discuss minor points (such as Mr. Butlers citation 

 of Philampelus satellitia Harris to Linne's species of that name instead 

 of to pandonis, where it belongs), or the larger questions as to the num- 

 ber of groups, Mr. Butler separating the Avibulkincc from the C/icero- 

 compi)ice, while Grote and Robinson in 1865 left them united. The 

 arrangement, indeed, is virtually that of our synonymical catalogue of 

 1865 ; the genus Acheroutia, not represented in America and left out of 

 consideration by ourselves, is made into a separate sub-family Acherontiince 

 by Mr. Butler. I wish merely to note here the changes which I am at 

 present willing to admit in the arrangement proposed in the " Check List 

 of North American Sphinges " published by myself in 1875. 



Hacmorrhagia (1. tS: R. 



1 do not admit that Buffalociisis and uiiiforinis are identical. The 

 former is smaller sized and there is a slight toothing or unevenness of the 

 inner margin of the terminal band of the primaries. The discal cell is 

 reduced and the transverse scale line tends to be absorbed by the scales 

 clothing the median vein. Nor do I admit that Kirby's nijicaiidis is the 

 same as inii/on/iis : I have shown that Kirby's description boldly contra- 

 dicts it. There is some warrant for believing that Kirby intended diffinis 

 or a species of Hanaris, as I have shown, Can. Ent., 6, 170. Mr. 

 Butler's rufimudis is probably iniifoniiis. The Albany collectors take 

 both Buffalociisis and imiformis (Mr. Lintner has reared Biiffaloensis), and 

 we may look for further careful and consequently decisive information 

 from them in regard to these points. Although Mr. Butler speaks 

 adversely, and perhaps a little vexatiously, on p. 518, as to the validity 

 of the genus, on p. 521 he says of Hai'/iiorr/uigia : "This may, perhaps, 

 be a genus, the species being more densely scaled than in Heiiiaris, and 

 having conseriuently a somewhat different aspect ; on the Avhole, however, 

 I prefer to regard it for the present as a section." The reason, if I 

 remember rightly, that we were not certain of the generic position of 

 radians was that we did not know the species, nor have I seen it since 

 1865. 



Callcnyo Grote. 



This term should be employed, 1 think, for carinata as distinguished 

 by Mr. Butler from Alcuron {chloroptera, etc.).
