mens, the four types being in Meyrick's collection. We have one speci- 

 men from Boulder, Colo., which Meyrick identified as his species, and 

 our personal comparison shows it to be almost exactly the same as 

 Fernald's types. Our one Alaskan specimen is the darkest which we 

 have seen, but retains the pure white and nebulous dark marks of 

 typical brucei. 



The life history is unknown.

 Vestiture of mixed gray-brown and whitish scales, the front of the 

 thorax and a space between antennae more whitish. Antennae white or 

 whitish with dark dots above, Palpi rather small, oblique. Abdomen with 

 scales on posterior margins of segments slightly roughened, bearing a pair of 

 black dots at least on a few segments near middle. Legs whitish; fore and 

 mid tibiae striped with dark gray-brown and provided with traces of scale tufts; 

 tarsi wiiite, usually finely annulate at tips of joints. 



Primaries white and gray brown, usually so evenly mixed as to produce 

 a gray ground color on which the whiter and blacker areas are more or less 

 conspicuous. Costa normally marked with a dash above base of cleft and a 

 shorter one just beyond middle of first lobe, both of which include the fringes. 

 The latter is preceded and followed by small dark dots, which scarcely enter 

 the white fringes. Either or both may be lacking. There is a blackish spot in 

 cell and a dash before cleft which is prolonged toward costal dash and some- 

 times connected to it by a fainter shade. Inner margin of first lobe with a dot 

 before apex, and second lobe with one to four such dots at apex and on outer 

 margin. The more evident whitish areas are a subcostal line before cleft, a
