an obvious cliscal spot. There is a small black dot, followed by a 

 larger white one at each indentation of the outer margin. 



Expands, 1.40-1.80 inches = 35-45 mm. 



Habitat. — Kaslo, British Columbia, in May and June; Kossland, 

 British Columbia, in early June; Arrowhead Lake, British Colum- 

 bia, in May; Cartwright, Manitoba, in June. 



Type. — Rutgers College Collection: cotypes U.S.N.M., Type No. 

 12024; also Cockle and Barnes collections. 



In the fine series of examples before me, 20 males and 18 females, 

 comprising material from Mr. Cockle, from Doctor Barnes, from the 

 U. S. National Museum, and from my own collection, this species 

 stands out from all its allies in the rich, dark coloring, especially of 

 the male, in which the blue powdering is more brilliant than in that 

 of any other species. As to the range of variation, that is, in general, 

 similar to that of minerea. In the male the blue scales may be re- 

 duced to marginal lines or they may form diffuse shadings; the 

 median space may be entirely concolorous. or it may be in whole or 

 part paler, more yellowish than the rest of the wing. In the female 

 the forewings may be almost uniform, or there may be a broad paler 

 shading that takes the outer half of the median space and extends to 

 the outer margin above the middle. 



This is the species referred to by Dr. Harrison G. Dyar as caly- 

 canthata, and the description of the early stages there given applies 

 here and not to Abbot and Smith's species. 



This is a close ally of minerea, and in fact is minerea intensified 

 and more brilliant. It may prove to be a geographical race when 

 the larvae of both forms have been compared ; but the fact that, with 

 so large a series of minerea covering 80 wide a range of territory, 

 there are none that in the male match the brilliant contrasts of 

 n <>/■</</, has induced me to keep this form distinct. 



The sexual characters are on the whole very much like those of 

 minerea; in fact, the small differences in detail that do appear I 

 would consider within (he range of specific variation in both sexes.
