THE CANADIAN ENTOMOLOGIST. 895 



figures the type oi idaJioefisis^ but the ground colour is rei)roduced a litile 

 too red, and the costa not gray enough. His figure oifurtivics is taken 

 from a worn Colorado specimen, determined by Prof. Smith as such, and 

 is almost certainly idahoensis. The intervening figure of foeminalii is 

 much more like a sm^dl specimen of my No. 270. It is taken, however, 

 from a specimen in Prof Smith's collection, where I saw it, besides others 

 there and at Washington, and it appeared to be a species previously 

 unknown to me. 



271. E. ?iordica Smith. — The male type from Calgary is more 

 uniformly gray than the majority of specimens. The female type is less 

 gray. Both are at Washington. Some dark and strongly-marked speci- 

 mens bear a distinct resemblance to divergens, and have the pale median 

 vein of that species, though less contrasting. Divergens, however, usually 

 differs in having the costal space more concolorous, but the subcostal vein 

 pale as well as the median, the latter forming a pale V at its junction with 

 vein 3. The s. t. line also is more direct in divergens, with less tendency 

 to form a W. Nordica at Calo^ary sometimes has a very decided reddish 

 tint throughout, and the resemblance then may be to my No. 270, which 

 formerly passed 2^% furtivus. 



Nordica occurs in Manitoba and Saskatchewan. It has been very 

 common during some seasons near Calgary, and i>, I think, to be met with 

 every year. I have taken it ui some numbers on the Red Deer River, in 

 the district now known as Dorothy. i\s I before pointed out, the record 

 from "B. C." under the description is erroneous, and the eiror is copied 

 in Dr. Dyar's and the B. C. lists. I have, however, seen a single speci- 

 men, supposed to be of B. C. origin, a male, dated July iith, 1904, in 

 Mr. A. H. Bush's collection at Vancouver. The specimen wiS in perfect 

 condition when I saw it, though Mr. Bush was not sure that he had not 

 taken it in a C. P. R. car. It is therefore possible that it may have been 

 a traveller. It was erroneously labelled '•///r//z/;/i'." East of the Rockies, 

 the form appears to intergrade with, and is not certainly distinct from 

 tessellata 2cc\di focinus (Nos. 263, 264, q. v.). Almost the only evidence I 

 can secure in favour of its distinctness is the absence, with the one excep- 

 tion above mentioned, oi /urttvus from a very large number oi tessellata 

 and fociniis which I have seen from Kaslo, Vancouver, and Vancouver 

 Island. There can be no doubt, however, that a certain variation of a 

 species does not always occur throughout its entire range. I may mention 

 here that a considerable number of i\\Q/ocinus recorded h^ Dr. Dyar in
