Oncocnemis siNGULARis sp. nov. (Plate II, fig. 6.) 



S. Head and thorax ochreous, latter largely suffused with black scaling; 

 primaries ochreous, heavily washed with black-brown, leaving scarcely any of 

 the ground color visible except at the base of wing; maculation indistinct; 

 basal line represented by a faint black mark on costa ; t. a. line defi;ied by the 

 difference in shade between the pale basal and dark median areas, ratlier ir- 

 regular, crenulate above inner margin; reniform and orbicular of the ground 

 color, defined by the surrounding black scaling of median space ; above reni- 

 form on costa some slight pale scaling around a dark spot which represents 

 the commencement of the t. p. line ; this latter defined by some pale ochreous 

 shading which separates the uniform dark median and subterminal areas, well 

 outcurved around reniform, incurved in the submedian fold ; a diffuse pale 

 patch above anal angle is all that is visible of the s. t. line ; fringes pale, check- 

 ered with dusky in their basal half. Secondaries whitish with a dark terminal 

 band, narrowing towards anal angle. Beneath primaries dusky, paler along 

 inner margin, marked with ochreous on costa; secondaries largely white with 

 slight traces of marginal band of upper side. Expanse, 24 mm. 



Habitat: — Christinas, Gila Co., Arizona (Liisk). i S. Type, 

 Coll. Barnes. 



The species resembles flagrantis Sni. from Death \'alley, S. Calif., 

 but Dr. Barnes, who has recently examined the type, considers it dis- 

 tinct ; it also shows marked resemblance to certain Bryomitna species 

 from the southwest, one of which is described later in this paper as 

 B. distaiis. It is possible that this species may represent a new generic 

 type, as the fore tibia is dilated at the extremity to form a plate, the 

 outer side of which is drawn out to a short .stout tooth, whilst the inner 

 side bears a long claw ; in this respect it appears to be midway between 

 Oncocnemis and Triocncmis Grt., but for the present it may remain 

 luider the former genus. 



LiKvoMiMA uisTANs sp. nov. (Plate II, fig. 10). 



Head and thorax pale ochreous, collar suffused with black; primaries pale 

 ochreous, heavily suffused with blackish-brown; basal line geminate, black, 

 crenulate, filled with pale ochreous, inner line of the two most distinct; beyond 

 basal line on costa a large blackish patch, occupying almost the whole of the 

 costal portion of the antcmedian space; t. a. line black, inclined outwardly, 

 rather evenly crenulate ; median space almost entirely filled with blackish 

 scaling, leaving at times a small pale border along t. a. line and inner margin ; 

 orbicular small, round, ochreous, outlined in black; reniform of the ground 

 color, with central dark line, not sharply defined ; t p. line bent outward 

 around reniform, then parallel to outer margin, dentate, black, shaded outwardly 

 slightly with whitish, beyond it on costa several pale points; subterminal space
