which is a dull gray species allied to clongelluin Dyar; the type of 

 uncanah- is presumably a 2 in the Hulst Coll. from Custer Co., Colo. 



Tlascala oregonella sp. nov. (PI. XXIV, Fig. 16). 



Very similar to umhripcnnis Hist, from Colorado but duller in color with- 

 out the shiny appearance and with the secondaries of a paler smokier shade 

 without the brown tints of Hulst's species; primaries with the basal area con- 

 siderably gray-sprinkled ; t. p. line distinct, gray, bent abruptly outward at vein 

 5 ; terminal space gray shaded. Beneath primaries dull smoky with traces 

 of a pale costo-apical spot bordered by black; secondaries pale smoky with 

 darker costa ; distinct pale basal fringe line. Expanse 27 mm. 



Habitat: Crater Lake, Oregon (July 16-23) (McDunnough). 2 ,J , 2 9 . 

 Types, Coll. Barnes. 



This may simply be a race of timbripcnnis but the above mentioned 

 points of distinction seem constant enough to warrant a name; the 

 species was taken among some low scrub pines at an altitude of over 

 8000 ft. and probably is a pine feeder. 



Melitara parabates Dyar. (PI. XXII, Fig. 21). 



This species (Proc. U. S. N. M. XLIV, 322) must be added to 

 our lists; we have a long series from various Arizona localities; it is 

 allied to dentata Grt. but is narrower winged, grayer and has a shorter 

 tooth in the t. p. line opposite cell. 



Olyca ponderosella sp. nov. (PI. XXII, Fig. 22). 



$ antennae ciliate ; palpi largely blackish, sprinkled with white especially 

 at base; basal tuft black with white sprinkles; front largely whitish; thorax 

 deep gray sprinkled with whitish ; primaries deep gray with heavy white 

 sprinkling ; the cross lines obscure in S , better defined in 9 ; t. a. line up- 

 right, dentate, with prominent tooth below cell, t. p. line obsolete at costa, very 

 oblique inwardly in lower portion, approximate to t. a. line on inner margin 

 where the two lines are obscured by a diffuse dark shade ; a black basal streak 

 extending along the fold to margin, usually broken in median area, a heavy 

 black streak in outer half of cell and all veins beyond cell distinctly lined 

 with black, the heavy streak of cell being continued more faintly above vein 

 S by a streak similar to those on the veins. Secondaries hyaline white, slightly 

 smoky outwardly in 2 . Expanse 37-42 ram. 



Habitat: Palm Spgs., Riverside Co., Calif. (Apr.). 5 $, 3 9. Types, 

 Coll. Barnes. 



The species is superficially similar to Cactobrosis strigalis B. & 

 McD. but is heavier and less smooth in maculation ; the distinct tufting 

 at base of palpi and on 3rd joint separate it generically from this 

 species.
