March, 1902.] Smith : New Noctuid^. 49 



Habitat. — Quartzsite, Yuma County, Arizona, in March ; Walters 

 Station, Colorado Desert, California, April 20 (George S. Hutson). 



Three males and four females in good condition and very much 

 alike. It is a typical desert species with the peculiar reddish suffusion 

 over a gray base and a powdering of black scales over all. I know of 

 nothing that resembles it closely in appearance and certainly nothing 

 that has the same generic characters. 



Crimona, gen. nov. 



Eyes naked, hemispherical, of good size. Head will developed, not prominent ; 

 front protuberant, roughened, vestiture flattened hair and scales, projecting straight 

 forward. Palpi not extending beyond the front. Tongue strong. Antennse in the 

 9 simple— male not at hand. Tibiae not spinose ; anterior short, broad, corneous, 

 with a single, median, claw-like process ; median normal ; posterior leg aborted, not 

 more than half developed. Vestiture flattened hair and scales ; patagise marked, 

 thorax quadrate, a well-marked posterior tuft. Abdomen with small dorsal tufts on 

 the basal segments. Primaries trigonate, costal margin nearly straight, apices well- 

 marked, outer margin very oblique, arcuate, with long fringes. 



Resembles Oncocnemis somewhat in appearance, but differs in the 

 abbreviated fore tibia and in the protuberant, rough front. The hind 

 legs are abnormal in their development, and this feature may be acci- 

 dental in this example ; but otherwise the insect is perfect, and the 

 degeneration is perfectly symmetrical. The genus seems not to con- 

 flict with any other known to me. 



Crimona pallimedia, sp. nov. 



Ground color a light mottled luteous, varied with ashen gray. Head and collar 

 pale luteous, with an admixture of white and black scales ; the latter more numer- 

 ous at the base of the wings. Patagise gray, the disk rather well powdered with 

 black scales. Thorax centrally luteous, the posterior tuft gray, black powdered. 

 The small abdominal tufts gray, else that part is very pale yellowish. Primaries with 

 basal space luteous, a little streaky, the yellowish shade narrowing toward the center 

 of the wing, but cutting the median space and expanding into the s. t. space which 

 is completely filled. Basal line wanting. Median lines interrupted. The median 

 space forms a somewhat elongate, trigonate gray patch on the middle of the inner 

 margin, and a much larger, triangular, gray area on the costa. These areas are lim- 

 ited by narrow black lines. Orbicular oval, whitish, with gray center, partly unde- 

 fined. Reniform large, kidney-shaped, outlined by a narrow black line, pale, with a 

 gray, powdery center. The terminal space is very narrow, gray, preceded by a pale 

 diff'use s. t. line, which is inwardly bordered by a darker luteous shading. A black 

 terminal line, more or less broken on the veins. The fringes mottled, ashen gray. 

 Secondaries whitish at base, darkening to a smoky extra-median shade : beyond that 

 is a whitish area which in turn darkens to a smoky border, sharply limited by a black 

 line at the base of the white fringes. Beneath white, with a broad blackish extra-
