Ent. See, XIII, 192, Dec, 1905), that being the genus to which Hamp- 



son refers pressa and most of our Platagroiis. The description adds r 



"It is a broad-winged form more like imperita than pressa^ and yet not 



unhke an obscurely marked pressa This may be really the 



male of discolor^'' and discolor is next described from two females from 

 "Inverness and mouth of Skeena River, B. C." The types of the latter 

 struck me as being like a white-grounded pressa. The suggestion that 

 they may be sexes of one species seems quite reasonable. It may take 

 more material from Northern B. C. to decide the matter, but if they are I 

 would suggest further that the differences are not necessarily sexual. I can 

 suggest nothing further about discolor for the present, but I believe /iz/^i- 

 to be merely a dull grayish pressa. I have specimens from Montreal, 

 Ottawa, "E. Ontario," Cartwright, ]Man., and Kaslo, besides four from 

 Calgary. Some eastern specimens are quite as gray as the local 

 series, and they grade through in colour and everything else to the 

 greenest. The type oi pressa is a female from New York, but Hampson 

 figures a male from "Canada." As a Calgary and California specimen 

 stood in the British Museum I admit they looked distinct from \\\^ pressa 

 series from New Yoik and "Canada," but I quite failed to draw any line 

 between the two series in Prof. Smith's collection. Nor can I agree that 

 fales resembles imperita in that collection as much as it does typical 

 pressa. The form should stand as pressa var. fales. 



193. Eiiretagrotis inattenta Smith. — I have a good series taken 

 locally and specimens from Cartwright and Miniota, Man., and Winder- 

 mere, B. C. I have also a series oi per at tent a from Montreal and Ottawa. 

 The eastern specimens are, as a whole, a bit brighter coloured and have 

 the maculation more clearly written, and all the black markings a little 

 heavier. I have one Calgary male, however, and have compared a similar 

 one from Redver's, Sask., from Mr. Crocker, which resembles some 

 eastern specimens almost exactly. I have local specimens grading almost 

 exactly up to this. I hesitate to make the reference definitely at present, 

 but have little doubt that the forms will be ultimately found to unite. I 

 have seen a series in Mr. Cockle's collection at Kaslo which my notes 

 say resembled the eastern rather than the prairie form, but have none 

 from that locality in my collection. I have one from Vancouver Island 

 which is certainly nearest the eastern form, but much brighter in colour> 

 almost vinous red. ]My local dates read from June 24th to August 2nd, 

 and it is occasionallv not uncommon at both treacle and light. The type of
