abdomen white. Both wings pale green; fore wings whitish on 

 extreme edge of costa; an oblique, rather broad band, straight in its 

 course, crosses the wing from just beyond the middle of the inner 

 edge to the outer fifth of the costa ; it is situated nearer the outer 

 edge in the ? . No other markings. Hind wings slightly paler than 

 primaries, with no markings. Beneath uniformly pale green, hind 

 win^s a little paler than primaries. Legs whitish, two anterior pairs 

 of tibias pink. 



Length of body cf, .55, ?, .45-50 inch; fore wing e?, .70, ?, 60- 

 .68 inch. Nevada (Edwards). 



The smaller of the two $ has paler hind wings, and an entirely 

 reddish front. The species may be recognized by the large size, the 

 want of any markings on the hind wings, and by the very slender 

 hind legs with the single pair of tibial spurs. 



Tephrosia nigroseriata n. sp. 2 d". 



Differs from any other Californian species by its rust red color, and 

 its two rows of black points. Palpi long and slender; antennas thick- 

 ened, ciliated. Head and thorax pale rust red, concolorous with 

 primaries. Fore wings not falcate, apex, however, subacutely 

 pointed; outer edge full, convex; hind wings not so sinuate as usual 

 on outer edge. Fore wings uniformly pale rust red, with obscure 

 scattered dark scales, and a slight dark discal point; two series of 

 black points, inner oblique, but not curved, angulated slightly on 

 costa; outer row of submarginal venular black dots, and a corres- 

 ponding series on hind wings. A row of fine black dots along the 

 base of the fringe. Hind wings with no apparent discal dot, paler 

 than fore wings, with no specks. Fringe concolorous with the rest 

 of the wing. Beneath of the same tint as above, with the row of 

 black submarginal dots common to both wings; no inner line. Hind 

 wings much more speckled with black than above, and with a con- 

 spicuous black dot. A dusky shade in the middle of the fore wings. 

 Abdomen long and slender, passing beyond the inner angle of sec- 

 ondaries. 



Length of body .55, fore wing .60 inch. California (Edwards^. 



The pale rust red tint, and two distant rows of black points, will 

 serve to distinguish this species from any described by Guenee. 



Tephrosia falcataria n. sp. l d. 



This species has remarkably falcate wings, the tip of the fore wings 

 being acute, the costa being more bent down at the tip, and the outer 

 edge excavated much deeper than usual; the costal area is wider,
