Euxoa floramina, n. sp. — Head, thorax and primaries powdery ashen- 

 gray over a luteous ground. Head with two transverse frontal Hnes. 

 Collar with two blackish lines, one just above the middle distinct, the other 

 just below the tip, obscure and sometimes wanting. Thorax confusedly 

 powdered with whitish scales, which tend to form paler edgings to the 

 patagia. Primaries confusedly marked, with all the transverse maculation 

 obsolete, yet hardly strigate. In the best marked examples the veins are 

 powdered with whitish, there is a diffuse basal blackish streak, to which 

 there may or may not be joined a small, loop-like claviform; there is an 

 ill-defined triangular sub-apical cloud and there is a dusky shading in the 

 median cell. The ordinary spots are narrowly pale ringed, concolorous, 

 not readily made out. The orbicular is narrow, more or less elongate,^ 

 oblique, irregular and rarely extends to or fuses with the reniform. The 

 reniform is moderate in size or small and of the normal kidney shape. 

 The small loop-like claviform is traceable in about half the specimens, and 

 when it is best marked a narrow blackish line extends from its tip to the 

 outer margin. There is a distinct pale terminal line preceded by black 

 lunules. Secondaries in the male snowy white, immaculate; in the female 

 evenly smoky. Beneath, whitish powdery; primaries more so than the 

 secondaries: all wings with a more or less obvious discal spot, that of the 

 secondaries tending to become lost; female darker than the male, 

 throughout.

Twelve c^ and five $ , most of them in at least fair condition. All 

 of these were, as I understand it, taken on flowers, in company with 

 Hollemanni and Nevada, to which this species is allied. It most nearly 

 resembles Nevada in appearance, but is smaller, much grayer, more con- 

 fusedly marked, the ordinary spots are rarely fused and the secondaries 

 in the female are evenly smoky instead of having a dusky outer border and 

 smoky veins. With a series of each at hand the differences are even more 

 striking than the description indicates. 



Euxoa taura, n. sp. — Head, thorax and primaries dull, smoky, gray- 

 brown; the first and second without defined markings, the primaries with 

 all the lines well defined, but without contrasting ornamentation. The 

 secondaries are dull pale yellowish to a well-defined extra median line, 

 beyond which the wings are blackish, forming a broad dusky border. The 

 abdomen is only a little paler than the thorax and the incisures are narrowly
