244 THE CANADIAN ENTOMOLOGIST, 



species in this group excluding ccerulea and conspicua. Slinger- 

 land gives us to understand that there are some very marked dif- 

 ferences in the male genitalia. Careful examination of numbers 

 of these might give enlightenment, and, in addition to breeding, 

 the forms require to be studied almost by the hundreds from various 

 localities. 



420. D. annexa Hy. Edw., syn conspicua Smith. — Edwards' 

 type is a male in the British Museum, labelled "West U.S.A., 

 Walsingham," and is the conspicua of Smith. It appears to agree 

 structurally with distincta, and has all the tibiae spined. It differs 

 in several points of structure from cuspidea. My series has been 

 reduced to two pairs, and I have no recent captures, though I oc- 

 casionally notice it in the spring. I have seen it from Similkameen 

 River in the collection of Mr. E. M. Skinner, of Duncans, B.C., 

 and there is a specimen in the British Museum, taken by Mrs 

 Nicholl in the Upper Keremeos. Both of these localities are in 

 Southern British Columbia, near the border of Washington. It 

 occurs at Banff. 



421. Enclidia cuspidea Hbn. — I have a specimen from Ed- 

 monton, taken by Mr. F. S. Carr. 



422. Syneda hudsonica G. & R. — The species is not liniho- 

 laris, which is correctly figured by Holland. No. 422 stands cor- 

 rectly named in the Neumoegen and Henry Edwards collections. 

 It was described from the Hudson Bay Territory. I have not seen 

 any type, but both sexes are figured with the description, and 

 appear to be this species. This is not the form figured by Holland 

 as hudsonica, which is referred to under No. 424. The female is 

 quite unlike the male, having the primaries much more evenly 

 grey, sometimes quite a blue-grey, with the maculation blurred, 

 indistinct. In this respect it differs strikingly from No. 424, 

 formerly listed as hudsonica, and in which the sexes are super- 

 ficially alike. It is not uncommon on the prairie, and occurs in 

 Manitoba, but I do not seem to have met with it here in the hills. 

 A day flier.
