THE CANADIAN ENTOMOLOGIST. 227 



broadest-winged of the series, with a base of lilac-bluibh, over which is the 

 prevailing wing colour, which ranges from a pale luteous to bronze-red in 

 one direction and smoky-gray in the other. The terminal space is always 

 pale, usually of the bluish base, and the broken median hnes are usually 

 accompanied by the same bluish shading, which gives the appearance of 

 light, mdefined bands across the wings. The characteristic appearance so 

 imparted holds in all the variations of colour and makes the species almost 

 unmistakable. 



The series of i6 c? 's and ii $ 's before me shows a beautiful range 

 in coloration ; the localities extending from Kaslo, British Columbia, on 

 the north, to the Chiricahua Mts., Arizona, on the south, and from Glen- 

 wood Springs, Colorado, on the east, to the Sierra Nevada, California, on 

 the west. The palest specimens are from California, the darkest from 

 British Columbia. Dates are from June to August in the northern pa!t of 

 its range, and from July to October in Arizona. 



R/iync/iagrotts scopeopSs Dyar. 



A very characteristic form, sim'lar in many respects to variata, but 

 much smaller, narrower-winged and the unusually large ordinary spots 

 annulate with the pile or bluish underlay. The wings have a mottled 

 appearance, especially along the costa and basal area, which separates it 

 ixom placida. Kaslo, B. C., is the type locality, and from it Mr. Cockle 

 has sent me a few examples for examination. I have a single male from 

 Newfoundland that I cannot separate, and which at present I believe to 

 be the same species. 



Fhynchagrotis p/acida, Grt. 



This specific name has served as a blanket for all the smaller narrow- 

 winged forms in which the terminal space is paler than the rest of the 

 wing and the colours range from red-brown to mouse-gray, the grays 

 predominating. There are really two forms concerned, the type placida 

 with an obvious median shade line in both sexes, the other without this 

 character. There are other differences in detail, but this is the most easily 

 noted superficial feature. The range of placida extends through the 

 northern United States and Canada from the Atlantic to the Pacific. I 

 do not have it from any southern locality at present. 



Rhy?ichagrotis negascia, n. sp. 



Similar to placida in size and general appearance, but with less 

 trigonate and more stumpy primaries. The absence of a distinct median 

 shade has been already noted, and, in addition, the ordinary spots are
