256 AMERICAN LEPIDOPTERA. 



line across middle, and that may or may not have some whitish mar- 

 gining scales above or below. Patagia somewhat powdered ; a white 

 line across base just behind collar. Disc of thorax somewhat white 

 powdered. Primaries with the usual 4-dentata maculation fairly well 

 defined. The costa is concolorous ; but the costal, sub-costal and 

 median veins are white, and the inception of the median lines is marked 

 by white dots on costa. Cell a little darker around the ordinary spots. 

 Basal line geminate, black, included space yellowish, inwardly oblique 

 below median vien. T. a. line geminate, black, included space lute- 

 ous, with a small outward angulation in the sub-median interspace 

 and a long outward bend below vein 1. T. p. line geminate, black- 

 ish, included space yellowish, slightly lunulate, as a whole almost 

 strictly parallel with outer margin. S. t. line yellowish or whitish, 

 broken, very even in course, indented on veins 3, 4, 6 and 7, which 

 are rayed ; the indentation on vein 6 being a little shorter than the 

 rest. Terminal space uniformly dark except at apex. S. t. space a 

 little paler beyond the t. p. line, darkened outwardly ; a series of 

 black, sagittate spots before the s. t. line. A series of small black 

 terminal lunules and a yellowish line at the base of the broad fringes. 

 Claviform narrow, extending half-way across the median space, black 

 lined, concolorous, followed by a yellowish streak to the t. p. line. 

 Orbicular round or nearly so, black ringed outside of a white annulus, 

 centre yellowish. Reniform kidney-shaped, not sharply outlined, 

 edged with black scales, with a whitish inward margin, centre yellow- 

 ish with darker markings. Secondaries white, veins more or less 

 dusky, a vague discal lunule and a narrow smoky outer border. 

 Beneath ; primaries smoky, powdery, with a darker extra-median 

 line ; secondaries white, powdery along costa, with a small black 

 discal dot and a very narrow, incomplete, dusky outer line. 

 Expands, 1.12-1.25 inches = 28-31 mm.

 VIII, 29. 



Six males and two females in fair condition. One male is 

 out of the Hulst collection from Colorado, one female from 

 Calgary is from Mr, Dod, the others are out of Judge Tru- 

 man's material. The specimens are all very much alike, 

 and differ chiefly according to their age and state of preser- 

 vation. The resemblance is to rumatana, also from South 

 Dakota, from which it differs by the absence of fuscous and 

 luteous shadings and the white secondaries, and to niveilinea, 

 which is a larger, brighter colored species, and has the white 

 line on patagia better defined, oblique, and not so near the 

 collar.
