into spots at apex, centrally, and at anal angle. Beneath silvery brown- 

 ish ashen, dusky along costa of primaries and terminally on all wings. 

 The geminate pale lines are defined by dusky shade lines, and in one 

 example the intra-discal is also thus depicted. Discal spot rather large, 

 linear, but not distinct, dusky. Marginal line and fringes as above. 

 Body beneath and legs white. Tip of abdomen darker, scaled as above. 

 On secondaries one or two basal hair-lines, short at injier margin. 

 Only the intra-discal hair-line runs thus; the small black discal point 

 and the extra-discal round out more widely about cell; with this the pale 

 geminate lines are parallel and as distinct as on primaries, bounded out- 

 wardly by another dark diffuse line ; terminal space showing the white line 

 very faintly, except in female type, where it is white and "spotty" toward 

 anal angle. Marginal line on all wings blackish, widely broken at veins. 

 Fringes moderate, same color as wings, darker at base. 



Type: Male and female are good examples of this small spe- 

 cies and were taken August 9 at L,as Vegas Hot Springs, New 

 Mexico, many years ago. They are in the U. S. National 

 Museum; type No. 13364. 



Eupithecia segregata, new species. 



Expanse, 18 mm. 



Palpi long, moderately stout, brownish, flecked with white scales. Head 

 and front similarly clothed, the vertex paler, antennas slender, flattened, 

 slightly ciliate. Thorax and all wings above soiled white, thickly sprin- 

 kled with dark brown and grayish scales. Primaries not much extended, 

 the margins slightly curved along costa and submarginally they are 

 heavily scaled and thus darkened. Two broad bands of similar scales 

 bound the discal space, the outer including the large round blac.c discal 

 dot, and between them a white space of equal width, traversed centrally 

 by a narrow brown hair-line. These bands runstraight toward outer mar- 

 gin across costa, the outer to vein 6, the inner to cell center, then turn at 

 a sharp angle and run with a basal trend toward inner margin, becom- 

 ing paler as they approach it. Basal area of wing pale, apparently without 

 lines ; beyond the outer dark band a broad pale band crosses, through 

 which run three faint hair-lines, the inner pair darker at costa, the outer 

 traversing the pale geminate line which forms the outer boundary of 

 pale space, leaving the narrow dark submarginal space, through which 

 runs a very fine white, wavy line, ending in a distinct twin spot between 

 veins 1 and 2. Marginal line black, broken at veins. Fringes dusky 

 brown at vein-tip, marked with spots of dark brown. Secondaries paler, 

 with brown scales heaviest along outer margin, the geminate pale line run- 

 ning close to margin; its outer edge, strongly crenulate, is clearly trace- 

 able. A broad central pale band is present as on forewings and three 

 dark lines which start from inner margin fade out centrally, the inner 

 reaching to the small round black discal dot. A triangle of black scales 

 on basal inner margin, abdomen above dark-brown and gray scales 

 mixed, the black band on second segment, broad at sides, is reduced to
