OP WASHINGTON, VOLUME XII, 1910. 139 



sides. Abdomen above white, mixed with gray brown, paler at base. 

 On second segment a narrow band of black, a narrow lateral stripe, and dor- 

 sal tufts black. Primaries much produced and sharp at apices. Ground- 

 color soiled white, clothed with brown so disposed as to leave all 

 cross-lines of the ground-color. Basal double, about one-third crosses 

 costa, then turns sharply, inclining toward base, straight to inner 

 margin. Intradiscal, also double, passes just outside the small linear 

 black discal dot, running in a line straight from costal edge toward outer 

 margin, thence at nearly a right angle, running parallel with basal line 

 to inner margin. Extra discal double line makes a sharp outward angle 

 after crossing costa, then in nearly a straight course, but with a strong 

 basal trend, reaches inner margin halfway between intradiscal terminus 

 and anal angle. Subterminal space darkened, centrally divided by the fine 

 zigzag whitish subterminal line. Marginal line dark brown, cut at veins. 

 A few black scales are clustered at apex, and above discal dot on costa 

 emphasize the beginning of a darker space crossing wing between the 

 double lines. Secondaries with ground-color as in primaries, with basal 

 and extra-discal lines of dark-brown scales crossing the wings, the for- 

 mer in a regular curve, the latter strongly rounded outward about the 

 small, diffuse, black discal spot, leaving the enclosed space rather clear 

 of scales. Outside this the double, clearly marked pale lines run par- 

 allel to it. Terminal space darker, centrally divided by a broad, irreg- 

 ular white line, parallel to margin. Marginal line dark brown. Fringes 

 pale on all wings, checkered with dark scales at end of veins. Basal area 

 darkened at inner margin, as are all the cross-lines. Beneath colored as 

 above, all the lines more clearly defined. Discal dots small, linear, 

 sharply defined, black. Body beneath white, abdomen paler than above. 

 Legs white sprinkled with brown scales. 



Type: One male, taken at Las Vegas Hot Springs, New 

 Mexico, August 13 (Barber, coll.). No. 13361, U. S. National 

 Museum. 



A female from the collection of the American Museum of 

 Natural History, New York City, No. 13246 of the Hy. Ed- 

 wards collection labeled "Havilah Calif.," I have made a 

 cotype with some hesitation, because of its condition. The 

 wings are more brownish than in type, but I can trace no other 

 distinction.
