line at base. Secondaries dull smoky brown at base, outwardly limited by a 

 black transverse band. Beyond this a broad white central band, the outer mar- 

 gin again broadly black. Fringes white, basally fuscous. Beneath both pairs of 

 wings fuscous gray at base, outwardly limited by a black band ; this followed by 

 abroad white band and margins again broadly black. Head and thorax concol- 

 orous with basal space of primaries; abdomen a trifle paler. Exp. 1.10 inches; 

 27 mm. 



Hah. — Nevada County, California (September). 



A single 9 i" collection U. S. N. Mus. from Dept. of Agriculture. 



The species is strongly marked and entirely unlike any other here- 

 tofore described. The common white transverse band is characteristic 

 and renders the species readily recognizable. Its general appearance 

 seems to refer it most nearly to the yellow underwings.

Head, thorax and primaries dull fuscous brown, the ordinary macnlation of 

 primaries distinct, though not prominent; blackish. Basal line present, black, 

 with a narrow following pale line. T. a. line distinct, oblique, sinuate, black, 

 preceded by an equally distinct pale line. Practically the line is geminate, the 

 inner portion reduced to a few dark scales defining the intermediate pale shade. 

 T. p. line distinct, geminate, inner line black, distinct, outer line punctiform, 

 the intervening space white, the white line becoming broader toward the inner 

 margin As a whole, the line curves outwardly over the reniform and is nearly 

 straight below vein 2. Claviform distinct, black margined, concolorous. Or- 

 bicular small, round, black ringed, with an inner white annulus. Between the 

 ordinary spots the cell is blackish, and from this point the narrow median shade 

 runs parallel with and close to t. p. line to the hind margin. Reniform rather 

 small, narrow, normal in shape, not very distinctly outlined, first black margined, 

 then with a paler annulus, centre of ground color of primaries. S. t. line irregu- 

 larly, but not strongly dentate, narrow, whitish, interrupted, preceded by a 

 series of small black spots, a few white scales in s. t. space opposite cell and a 

 rather large, indefinite pale spot filling the space near hind margin. A row of 

 black terminal lunules. Fringes dusky, cut with darker fuscous and with a 

 fuscous line at base. Secondaries smoky at base, limited by a sinuate black band, 

 then a narrow white band followed by the broad black outer margin. Fringes 

 white. Beneath both pairs of wings smoky at base, with a common black me- 

 dian band, followed by a broader white band, the outer margin broadly black. 

 Expands .88 inches; 22 mm. 



Hah. — Colorado. 



A single female in Mr. Tepper's collection ; the species is an easily 

 recognizable one. Its small size and the banded secondaries are 

 unusual. The primaries are somewhat broader and shorter than 

 usual, and the body somewhat more robust ; the eyes are not very 

 distinctly lashed. 



Despite its somewhat abnormal appearance I believe the species 

 correctly referred here.
