are reddish powdery, with the disc a little smoky. The secondaries have an outer 

 blackish line and a fairly distinct discal spot. Expanse, I inch=25 mm. 



Habitat: Park County, Colorado; 10,000 feet. Bruce. 



The type is a unique female from the collection of the U. S. Nat- 

 ional Museum, and it is therefore impossible to say to which section 

 the insect belongs. It has, however, the apj^earance and some of the 

 characters of trifascia, and may be associated with that species for the 

 present. It is a small species with stumpy wings and the mottlings of 

 red brown with the white scales on the median lines give it rather a 

 distinctive appearance. 

 Xylomiges pallidior, sp. nov. 



Ground color white, flecked with black and smoky scales ; lines and dots black, 

 shading smoky. Head with a black frontal line. Collar with a broad black central 

 line. Thorax with a few patagial scales black tipped and a black margin at the base 

 of primaries. Abdomen cream yellow. Primaries with a black basal streak, reach- 

 ing to the t. a. line. Basal line indicated by a white break in the smoky shading of 

 the costa. T. a. line fragmentary and marked chiefly by the endings of the maculation 

 that usually starts or terminates there, on the costa and internal margin by a smoky 

 shade. T. p. line marked by the geminate spots on the costa, is then single, smoky 

 over the- cell, black, linear and denticulate on veins 2, 3, 4, smoky, broken and 

 linear to the hind margin. S. t. line consists of a series of interspacial, somewhat 

 elongate black spots, the third from the angle a little out of line and nearer the mar- 

 gin, dividing the series into two groups. Median shade prominent, from costa outwardly 

 oblique along the upper margin of the orbicular, forming an acute angle on the me- 

 dian vein, smoky to the end of the claviform and filling the space below vein I to the 

 t. a. line. Claviform concolorous, very large and broad, extending almost across the 

 median space, the outline black. Orbicular white, incompletely black bordered, ir- 

 regular, elongate, oblique, very large, extending to the end of the cell in the form of 

 a loop along the median vein. Reniform indicated by an obscure smoky lunule, but 

 not at all outlined. There is a series of black terminal dots, beyond which is a 

 smoke line through the fringe. Vague smoky shadings are along the costa and inter- 

 nal margins and slight darkenings in the s. t. and terminal spaces. Secondaries 

 white, with a large, half round discal spot a venular median line and a narrow termi- 

 nal line, black. Beneath white, primaries powdery along the costa : a common ven- 

 ular extra-median line and a discal spot, small on primaries, large on secondaries, 

 black. Expanse, 28 mm. =^ 1. 52 inches. 



Habitat : New Westminister, British Columbia (Fletcher). 



One female only, in fine condition. The insect is, in markings, 

 an exaggerated simplex with white instead of gray ground color and 

 without the shadings of the older species. This white color on which 

 the huge claviform and orbicular spots are outlined in black will serve 

 to identify the species ; the other prominent character being the 

 broad oblique costal portion of the median shade.
