nent on the costa and is then broken into somewhat triangular spots. A series of un- 

 equal terminal black spots beyond which the fringes are cut with black. Claviform 

 indicated by black scales. Orbicular moderate, upright, oval, concolorous, incom- 

 pletely outlined. Reniform large, almost lunate, outlined by black scales, the center 

 a black diffuse lunule. A black median shade is marked on the costa, forms a black 

 square between the ordinary spots and is traceable, though powdery, to the inner 

 margin. Secondaries smoky over a white base, with a series of black terminal 

 lunules and a reflection from the outer line and discal spot of the under side. Be- 

 neath, white, more or less powdery, with an outer blackish line, a discal spot and 

 a broken black terminal line ; primaries with the costal region and disc darker. 

 Expands 1.48 inches =37 mm. 



Habitat: Cartwright, Manitoba, May 7. 



One female, in good condition from Mr. E. F. Heath. This is a 

 beautiful species, larger than the eastern form and obviously distinct 

 by the geminate median lines and better defined ordinary spots. 

 Epidemas obscurus, sp. nov. 



Ground color dull smoky gray, with a brownish tinge in primaries. Head and 

 thorax concolorous, tending to gray tippings. Primaries with the maculation fairly 

 defined, but in no wise contrasting or prominent. Basal line not obvious. A slender, 

 slightly curved black basal streak, which does not extend more than half way to the 

 t. a. line. T. a. line single, black, slender, outwardly angulate in the interspaces, as 

 a whole a little oblique. T. p. line geminate, the outer part even, smoky and in- 

 complete ; inner portion brown, a little lunulate, included space a little paler and with 

 some white scales : as a whole abruptly bent over the cell, then evenly and not 

 greatly incurved below. S. t. line a little paler, broken, indicated by a few whitish 

 scales and by a darker preceding shade on costa and darker terminal space below the 

 apex : a small W-mark is obvious on veins 3 and 4, and in the submedian interspace 

 the line is emphasized by a brown shading on both sides. Fringes long, gray, cut 

 with smoky, with a blackish interline and a blackish line at base. There is an ob- 

 scure median dusky line, defined only below the median vein. Claviform concolor- 

 ous, broad, extending half way across median space, incompletely outlined, connected 

 by a blackish double shade with the t. p. line. Orbicular narrow, oblong, oblique, 

 of the palest ground color, outlined in black or smoky. Reniform large, kidney- 

 shaped, gray, inner portion outlined by black or gray scales, outer obscure, diffuse. 

 Secondaries soiled whitish, with a smoky line at base of fringes, an extramedian 

 smoky line and a dark discal lunule : the tendency is to a darkening between the extra- 

 median line and the outer margin. Beneath powdery, with a blackish extra-median 

 line and discal spot on all wings: primaries smoky gray; secondaries whitish. 

 Expands 1.08-1.36 inches := 27-34 mm. 



Habitat : Pullman, Washington, October 14 and 26. 



Three males and one female received from Prof. C. V. Piper, none 

 of them in good condition and the smallest example — the female — 

 probably undersized. The species is congeneric with cinerea which I 

 have from the same locality, but it lacks all contrasts and is altogether
