NOTES ON THE DESCRIBED SPECIES. 



Sccllns c.vnslns Walk. This large, black species is so strik- 

 ing that there can be no doubt that it was the one described 

 by Walker, although he mentioned only a few of its characters. 

 I have specimens from Brookings, South Dakota, Montana, 

 and Moscow, Idaho. I have only collected it in beating about 

 the grass of low meadows, and have never seen a specimen 

 before I got it into my net ; hence, I do not know its exact 

 habitat. 



Sccllns az'idns Loew. This I have only seen in a set of 

 specimens given to me by Professor Win. M. Wheeler, col- 

 lected by him September n, 1895, on Hunter's Creek, 

 Wyoming. The type locality was Fort Resolution, Hudson's 

 Bay Territory. It is one of the larger species, the tooth on 

 the anterior side of the fore tibia is near the base ; the ribbon- 

 like anal appendages are white, blackish at base and tip, with 

 a tuft of brown hairs on the end of the black, spoon-shaped 

 apical part. 



Scclhis spininianus Zetterstedt. This European species was 

 recognized by Loew in material from Fort Resolution, Hud- 

 son's Bay Territory. As far as I know, no one has seen 

 it from North America since. It should be easily recognizable. 



Sccllns monstrosns O. S. I examined a male of this species 

 in the University of Kansas collection, captured at Estes 

 Park, Colorado ; it is the only specimen I ever saw. The type 

 locality was British Columbia. It has many characters in 

 common with virago, differing in the antennal structure and in 

 having a long, curved spine at the apex of the hind tibia, etc. 



Sccllns vigil O. S. Type locality, Webber Lake, California, 

 "resting on stones on hillsides." No other species of the gem^s 

 is known to rest on stones, and I found this rather common 

 ten years ago in the vicinity of Moscow, Idaho, on trunks of 

 pine trees ; hence, I am a little doubtful about the data of Osten 

 Sacken. I also got the species on the side of the university 

 building, however. It is a small species, with pale wings. I 

 have got no more specimens for some years now. 



Scellus filifcnts Loew. I collected this at Custer, South 

 Dakota, on pine trunks, and near Moscow. Idaho, in the same
