indefinite, the markings are reduced and increased in contrast, the 

 inclosed parts of the median lines and filling of the ordinary spots 

 being white. The species is not common in collections at any time 

 and the occurrence of this unusual form in a new locality is worthy of 

 note ; hitherto the species has not been recorded at all from the Pacific 

 coast, so far as I am aware. 



Aplectoides arufa, new species. 



Resembles in general appearance A. imperita, but has none of the reddish or 

 brown shadings of that species and is altogether less marked. The ground color is a 

 dull fuscous gray, the markings darker, emphasized by a few black scales only, and 

 there are none of the contrasts that make the eastern species so recognizable. The 

 median space is concolorous, the median shade is vaguely defined, and there are no 

 black marks on the s. t. line; but the terminal lunules are large and distinct. The 

 secondaries are smoky, whitish at base, with a broken terminal line, a dusky discal 

 lunule and a smoky extra-median line. 



Expands : 1.50 inches = 37 mm. 



Habitat. — Yellowstone Park, Wyoming, in August. 



One good male. The relationship to the eastern species is ob- 

 vious ; but so is also the difference. I have imperita from Labrador 

 that are smaller with much more sharply defined markings than my 

 example from Mt. Washington and, while the New Hampshire speci- 

 mens differ among each other, none of them vary in the direction of 

 arufa. 



Aplectoides fales, new species. 



Head, thorax and primaries a rather even smoky gray, with a slight olivaceous 

 tinge. Head and collar somewhat paler, with a slight reddish admixture. Dorsal 

 tuftings of thorax with a brown shade ; patagia well marked. Primaries without 

 strong contrasts, all the maculation traceable, the ordinary spots and an area between 

 reniform and s. t. line on costa more whitish. Basal line distinct, geminate, black- 

 ish, with whitish included space. T. a. line geminate, outer defining portion black- 

 ish, inner smoky ; included space ashen gray ; as a whole the line is outwardly 

 oblique, a little curved, with small outcurves in the interspaces. T. p. line geminate, 

 inner portion blackish to black, lunulated ; outer portion obscure or smoky, crenu- 

 lated, included space gray ; as a whole the line has only a slight outcurve over the 

 cell and only a very little incurve below it. S. t. line gray, a little irregular, pre- 

 ceded by a distinct black shade which becomes inwardly diffuse and is the most con- 

 spicuous-portion of the wing. There is a slender, lunulate black terminal line. A 

 vague median shade darkens the space between the ordinary spots and part of the 

 outer portion of the median space. Claviform concolorous, small, pointed, narrowly 

 black lined. Orbicular large, pale gray, not defined above, broadly V-shaped. 

 Reniform moderate in size, kidney-shaped, gray, rather well defined by a narrow 

 black line. Secondaries an even smoky gray, the fringes white. Beneath pale gray, 

 powdery, both wings with smoky outer hands and smoky discal spots.
