wings ; all wings with discal dot. Beneath pale ochreous with black discal dots 

 and traces of the t. p. line of upper side. Expanse 35 mm. 



Habitat : Redington, Ariz. 3 $ , 2 9 . Types, Coll. Barnes. 



The species bears such a close general resemblance to semiclu~ 

 saria Wlk. that we place it in Nepytia in spite of the fact that the $ 

 hind tibse have hair pencils ; the course of the cross lines is much 

 as in nigrovenaria Pack, without the strong bend at costa. 



Plat^ea triangularia sp. nov. (PI. Ill, Fig. 18). 



Primaries whitish to s. t. line, sparsely sprinkled with gray; terminal area 

 olivaceous ; a large semitriangular olivaceous patch occupies the median area of 

 the wing, the base resting on costa, the apex just above the center of inner mar- 

 gin, the outer edge bent inward in the cell and connecting with a small white 

 discal spot; s. t. line white, angulate on vein 5, preceded by a narrow smoky 

 shade band ; apex of wing slightly falcate with the outer margin toothed on 

 veins 6 and 4; secondaries light brown shading into whitish at base, outer mar- 

 gin entire. Beneath whitish, slightly speckled, with maculation of upperside 

 partially visible. Expanse 25 mm. 



Habitat: Palm Springs, Riverside Co., Calif. (April). 1 $. Type, Coll. 

 Barnes. 



This may be a mere aberration of one of the described species 

 but if so it is a very beautiful one and worthy of a name. 



Morina curvata sp. nov. (PI. II, Fig. 17). 



Primaries dark gray with rather indistinct maculation ; t. a. line obsolete 

 or represented by a few indistinct marks near base of wing; t. p. line from costa 

 near apex, pale-shaded outwardly and parallel to outer margin as far as vein 2, 

 then curved inward to about middle of inner margin, accentuated on the veins 

 by dark dots ; a dark median shade line parallel and closely approached to the 

 t. p. line with the intervening area rather paler than the basal and remaining 

 median portion of wing ; a whitish crenulate s. t. line parallel to outer margin ; 

 terminal dark line ; fringes smoky, faintly checkered ; secondaries whitish, 

 dusted with smoky outwardly and along inner margin with traces at inner margin 

 of a smoky antemedian band, a median line edged outwardly with white and a 

 white s. t. line edged inwardly by a smoky band ; a terminal dark line and 

 slightly smoky fringes. Beneath whitish, peppered with smoky. Expanse 22 mm. 



Habitat: La Puerta Valley, S. Calif. 4$, 2 ?. Types, Coll. Barnes. 



The species differs from coniferaria Grossb., the type of the genus, 

 in having the t. p. line evenly curved and not wavy as in the latter 

 species. 



*Pterot.ea tremularia sp. nov. (PI. II, Fig. 4). 



Thorax light gray crossed by a black line at apex of tegulae; primaries 

 pale to dark gray, sprinkled lightly with smoky; t. a. line black, bent outward 



*This is probably Cleora Melanocarpa Swett the description of which has just ap- 

 peared.
