wing; it is probably closer to laciniellus Grote, but lacks the white 

 terminal line of that species and also has much darker hind wings. 



CRAMBUS NEVADELLUS, new species. 



Expanse, 17-26 mm. 



Head pale ochreous; labial and maxillary palpi dark ochreous, 

 paler internally ; antenna ochreous brown ; thorax pale ochreous, 

 darker laterally; abdomen pale ochreous, first three segments shaded 

 above with darker ochreous; legs whitish ochreous, shaded with light 

 brown. 



Fore wing light ochreous brown, darkest on upper half, gradually 

 shading into whitish ochreous on outer third ; below the fold the wing 

 is streaked and mottled with white, especially on outer two-thirds, ex- 

 cept over vein P, which is brown; on the fold is a dotted line of 

 white; between the fold and P the whitish shade is dotted with a 

 darker brown in a line paralleling the fold; over vein 2, half way be- 

 tween end of cell and termen, is an irregular dark brown line, pre- 

 ceded by a white patch ; vein 3 is similarly marked. In the majority 

 of specimens before me these white and dark brown scales on lower 

 half are absent, partly obsolete, doubtless from their transient char- 

 acter. The brown subterminal line is curved outwardly from costa 

 to below middle, then obliquely inward to dorsal margin; it also is 

 more or less obsolete in some specimens. There is a more or less 

 distinct dotted dark line preceding the cilia. The latter is whitish 

 at base and pale ochreous outwardly. 



Hind wings above and below light gray, cilia paler. Underside 

 fore wings dark grayish ochreous. 



The majority of the specimens are rubbed and present a different 

 appearance from the above description. Color, both above and below 

 middle, pale ochreous, a dark brown median streak from base to end 

 of cell, broken at middle of wing by ground color. Other marks, ex- 

 cept the subterminal line, are almost obsolete. 



Thirty specimens, Verdi, Nevada, June 10-30, Sierra Xevada 

 Mountains, on border line between California and Xevada, collected 

 by A. H. Vachell. 



Nearest to trisectus Walker and albolineellus Fernald, differing 

 from both by the narrowness of the fore wing. 



Cotype.— Cat. No. 11954, U.S.N.M., and in Author's collection. 



CRAMBUS SIMPLICIELLUS, new species. 



Expanse, 23-31 mm. 



Head, thorax, and fore wing, light ochreous gray; both pairs of 

 palpi are white internally, speckled ochreous gray outside; antenna 

 ochreous brown in front, frosted with white elsewhere; abdomen
