cell is black filled around the ordinary sj^ots, and a blackish shading 

 is in the basal space below the median vein, shading to the ground 

 color inferiorly, sharply limited above. Basal line marked by geminate 

 black spots on the costa, and by a gray line interrujjting the black below 

 the median vein. Transverse anterior line geminate, interrupted by 

 the pale costal shade, outwardly oblique and outcurved in tbe inter- 

 spaces below that point. Transverse posterior line geminate, the inner 

 line crenulate, outer even and not so well marked ; as a whole, evenly 

 curved over the cell and a little drawn in below. Subterminal line 

 pale, irregular, a little dentate on veins 3 and 4, defined by the dusky 

 terminal space which leaves the apex of the ground color, and a dusky 

 preceding shade which is best marked on the costa and is more or less 

 broken into undefined spots elsewhere in its course. A broken blackish 

 terminal line, followed by a yellow line at the base of the fringes. 

 Claviform black ringed, variable in size, though never very large; a 

 fine black line from its tip through the submedian interspace and a 

 slightly paler shading above it. Orbicular oblique, oval or oblong, 

 open to the costa superiorly in the female, incompletely closed in the 

 male. Reniform upright, kidney-shaped, of good size, hardly extending 

 below the cell, defined by a gray annulus and the center more or less 

 gray powdered. The median vein is gray to the reniform, and a powder- 

 ing of gray scales is variably evident along the inner margin. Sec- 

 ondaries smoky, more yellowish at the base, darker in the female, 

 fringes whitish. Beneath, primaries smoky, secondaries gray, pow- 

 dery; all with an incomplete outer line and a discal lunule, the latter 

 usually obsolete on the ijrimaries and sometimes so on the secondaries. 



Expanse, 35 to 38 mm. = 1.40 to 1.52 inches. 



Habitat. — Calgary, Canada, July 16, 19, August 3 (Dod); Olds, 

 British Columbia (Fletcher). 



Two males and two females. Is an ally of diver gens and has the pale 

 median vein; but the ordinary spots are not outlined in pale and are 

 different in shape, opening on the pallid costa. This is also a much 

 grayer species and the contrast are more sharply marked. It has a 

 little the ai^pearance of furtivus, but the powdery markings and com- 

 plete median lines easily distinguish it. 



Type.— Cat. No. 4786, U.S.if.M. 



51. CARNEADES FACTORIS, new species. 



Ground color fawn gray, more or less brown shaded. Collar with a 

 transverse black median band which is diffuse inferiorly, and tends to

 and flattened hair, j)atagia fairly defined, tuftings obscure. Primaries 

 with all the markings somewhat broken, median space a little darker 

 red brown, costa a little more shaded with gray, cell yet darker or 

 blackish before and between the ordinary spots. Basal line geminate, 

 marked by black spots on the costa and by the paler included shade
