THE CANADIAN ENTOMOLOGIST. 321 



strigse are coarse and irregularly distributed, and the median lines 

 are fragmentary and indicated rather by cloudings or groupings of the 

 strigse. Almost all the examples are more or less mottled along the costal 

 area with yellowish, and atoms of this colour are more or less obvious 

 throughout the wing. The median shade may hd absent or may form a 

 cloud, taking in most of the median space. The s. t. line is yellowish, 

 usually distinct and usually also with a fragmentary preceding shade. The 

 ordinary spots are large, outlined in yellowish, the reniform dusky, orbicular 

 irregular and reaching to or uniting with the reniform more frequently than 

 in the other forms. 



Unfortunately, in the series of lo specimens, there are only two males ; 

 but these are alike in genital structure and are quite different from any 

 other species. The uncus is rather stout, drawn out to a gradual point. 

 The harpes narrow to an unusually short small tip, which has only a little, 

 short acute process inferiorly and has the upper angle rounded. It represents 

 the extreme in reduction in this series. The clasper is stout, moderate 

 in length, not so much curved, and is distinctly enlarged or dilated at 

 about its middle. Figure 4 shows obviously the characteristic differences 

 between this form and all others of the series. 



Localities are: Garfield Co., Colo., 6,ooo ft. (Bruce); Glenwood 

 Springs, Colo., May 6 (Barnes) ; Denver, Colo., IV, 20. 



On the Pacific Coast there are three or four species aside from the 

 true pacifica^ but the material is not so satisfactory in this series as I 

 could wish. 



First of all is a species that I call inflava. It is quite a uniform 

 carneous-gray, not mottled, without transverse strigee, median lines lost, 

 F. t. line very distinct, yellow, with scarcely marked preceding shades, the 

 ordinary spots distinctly outlined in yellow. The very even colouring, 

 contrasting s. t. line and rather conspicuous ordinary spots characterize 

 the species superficially. 



I have only two males and one female from Pullman, Washington, 

 and Vancouver, B. C, all taken in April. The males, which resemble 

 each other closely, although they come from the two extreme localities, 

 differ in genital structure from all the other Pacific Coast forms by having 

 the tip of the uncus spear-shaped. In other respects the resemblance lo 

 inherita is rather close, as an examination of figure 5 will make clear. I 

 believe this to be a good species, but the material is scant and the possibility 

 of error is not excluded. 



Inherita m\^\. be mistaken at first for a well-marked, robust malora. 

 It is generally pearl-gray, but occasionally becomes tinged with reddish.
