The spinulation of the middle tibia is not strongly marked, and 

 in the male not easily demonstrated in the thick vestiture. The 

 sexual tufting on the middle femora of male is not conspicuous and 

 the mass of specialized scales is small. 



The genitalia of the male are of the general type in the group, 

 and while they differ in detail from the related species, offer nothing 

 conspicuously peculiar. 



In the female the impressions on the upper surface of the anal 

 segments are very well marked, and the lobes of the under side are 

 equally obvious. They are less asymmetrical than usual and the 

 opening to the copulatory pouch is at the upper inner angle, coming 

 from the upper margin rather than the angle. 



PH.ffiOCYMA BETHUNEI, new species. 



Ground color dull smoky brown, with a more or less well defined 

 rufous tinge, which is conspicuous in all cases on the primaries, be- 

 tween the reniform and t. p. line. Head concolorous. Collar with 

 a black line at base, a smoky line across the middle, and a blackish 

 line at tip; each line may be edged. with white scales and, on the other 

 hand, all the lines may be lost or barely indicated. Two gray lines 

 cross the thorax, and these may be quite distinct or barely traceable, 

 while in flown examples they may appear to be altogether absent. 

 Abdomen dull brown, terminal segments often ocherous; dorsal tuft- 

 ings very distinct. Primaries with the vestiture a little uplifted 

 so that the wing has a sort of velvety appearance, on which all the 

 markings appear somewhat diffuse and none are sharply limited or 

 contrasting. Basal space usually darker and apparently crossed 

 by transverse dusky shadings. Basal line traceable in most speci- 

 mens. T. a. line darker brown or blackish, single, irregularly out- 

 curved, with a little outward tooth on the subcostal and a more 

 obtuse bend on the submedian. The median shade is upright and 

 may consist of a solid broad band of smoky brown or blackish, or 

 of two parallel diffuse lines close together, broadening a little on 

 the cell so as to include the narrow lunate reniform which is rarely 

 separate from the band. Before this median band there may be a 

 gray powdering, and between it and the t. p. line there is usually 

 a decided reddish tinge which, as already noted, becomes most con- 

 spicuous just beyond the reniform and, in fact, gives the impression 

 of a large, kidney-shaped, discolorous reniform. T. p. line brown to 

 blackish, single, outwardly toothed on veins 4 and G, with a deep 

 inward indent al ion between and strongly incurved below the cell. 

 S. t. line fending to become lost through the upper part of its course, 

 and always better marked below middle; forms the usual obtuse 

 outward angulation at its middle, and incurved from that point 

 toward costa and inner margin. There is a more or less obvious 

 dentate terminal line al base of the paler fringes. Secondaries
