OF WASHINGTON. 55 



One male, Orizaba, Mexico (R. Miiller, No. 1293). 

 Type. — No. 11357, U. S. National Museum. 

 Allied to H. pagana Schaus, but the discal mark much less 

 contrasted, while the lines are more continuous and distinct. 



Hemiceras muscosa Schaus. 



In a series of specimens the whitish purple irrorations of the 

 type are gradually evanescent, till in the last they can scarcely 

 b^ distinguished. The type is from Colombia. Others are 

 before me from Brazil and Venezuela, all with less purplish 

 than in the type. 



Hemiceras evanescens, n. sp. 



Vertex largely white, collar and thorax purplish brown, abdomen 

 grayer above, yellowish below, with a slight ventral purplish tint. Fore 

 wing shining purplish brown, rather dark, uniform; lines crenulate, 

 subobs^te, indicated by blackish dots on the veins, the inner gently 

 curved, with a slight bronzy ochraceous edging towards the base, outer 

 oblique, reaching costa before apex, distinct below the submedian fold 

 and edged within the black dots by a little white powdering and white 

 dots on the veins ; discal mark a faint dark rounded cloud ; a large 

 indeterminate dark shading on the outer margin reaching up centrally 

 to the outer line. Hind wing dark brown. Expanse 44 mm. 



One female, Tabernilla, Canal Zone, Panama (A. Busck). 



Type. — No. 11358, U. S. National Museum. 



Allied to H. muscosa Schaus, but without a tooth on the 

 anal angle of the fore wings, the subbasal tooth also being 

 slight. There is no male, so the generic reference may pos- 

 sibly be in error. 



Hemiceras cotto, n. sp. 



Head with a few whitish hairs, the collar and thorax purplish brown; 

 abdomen grayer brown dorsally, the venter yellowish. Fore wing broad, 

 trigonate, theteeth at anal angle and near base of inner margin strongly 

 developed; color purplish brown, rather pale, marked by two bronzy 

 shades, one in lower part of median space, crossing the outer line, the 

 other extending from just beyond the discal mark to outer margin 

 above tornus; a similar fainter shade defines the subterminal line 

 above ; lines slender, blackish, without pale edges, the inner strongly 

 angled inwardly on both folds, the outer crenulate dentate, reaching 

 costa before apex ; discal mark a distinct, rounded blackish cloud. 

 iht^d wing brown shaded, paler toward the base, the male stigma dark 

 brown, not contrasted, the fringe whitish. Expanse 34 mm. 



One male, Orizaba, Mexico (W. Schaus). 

 Type. — No. 11359, U. S. National Museum.
