292 THE CANADIAN ENTOMOLOGIST. 



typical dusk-flier. Mr. McGlashan informs us that he always takes his 

 specimens at dusk ; the Hymers specimens were also captured at this 

 time of day. Taking all the above points into consideration, we are 

 inclined to think that, if not synonymous with ganna, MacG/ashatii is a 

 perfectly valid species. 



II. Matthewi H. Edw. 



Species described from Brit. Columbia, listed by Dyar as variety of 

 hyperboreus. Dr. Barnes possesses only a single rubbed male from 

 Victoria, B. C, which is too poor to make much of. From the description 

 it might be closer to MacGlashani than hypei-boreus. The male alone was 

 described. It behooves our Western friends to furnish good series of this 

 in both sexes. 



H. confusus H. Edw. 



The type was a single specimen from Alaska. The silver banding 

 appears from the description to be replaced by pale fawn, but we have 

 seen neither the type nor any specimens agreeing with the description. 

 We do not know Dr. Dyar's reasons for placing it as a variety of 

 hyperboreus. 



H. roseicaput N. & D. 



Described from a single male (?) from Cascade Mts., B. C. The 

 description reads rather like that of our female pulcher from Mt. Hood, 

 except that this latter species has no blackish subterminal line. Possibly 

 this may be the 9 of Mattheivi, described in error as a male ; the locali- 

 ties are certainly closely approached.
