maries lack the orbicular and reniform, besides being much paler and 

 possessing olive-brown tints not found in hiclavis. The species might 

 be referred equally well to Porosagrotis, Feltia or Lycophotia, which 

 are mixed genera and upon which the authors will probably publish 

 in the near future. It is not a "Carneades" ("Euxoa"), the clasper 

 not being "bifurcate." It may well be recalled that Dr. Smith de- 

 scribed denmtabilis as Peridroma. The present species would key to 

 Lycophotia in Hampson, Cat. Lep. Phal. B. M., IV, but is tentatively 

 placed in Rhizagrotis following cloanthoides, pending revisional work 

 in these mixed genera. 



There are a number of topotypes in the Barnes Collection dupli- 

 cates which have not been made paratypes because of their poor con- 

 dition; also two specimens from Palm Springs, Riverside Co., Calif., 

 March 7 and 8, 1921 (Karl R. Coolidge) ; and one, Clark Co., Nev., 

 March 16-23, 1921 (O. C. Poling). The species is also represented 

 in the personal collection of the junior author by two specimens from 

 Indio, Calif., (E. Piazza) and in the Cornell University Collection 

 from the same locality. 



Type locality: Dixieland, Imperial Co., Calif., March 1 to April 15, 1922;

Number and sexes of types: S Holotype, 1-15 March; ? Allotype, 1-15 

 March; 348 Paratypes, about equally divided as to sex. 



ERASTRIANAE 



Sexserrata, gen. nov. 



Type: Sexserrata hampsoni, sp. nov. 



Eyes : smooth, unciliated, round, large. Proboscis : fully developed. Palpi : 

 obliquely porrect, extending beyond the vertex, first joint broadly scaled below, 

 second joint moderately scaled below, the third joint smoothly scaled and about 

 one-third the length of the second. Frons : with a cup-shaped prominence with 

 raised edges and a bifurcate central horn composed of a moderately long lower 

 point and an upper point, from near the edge of the prominence, nearly as long 

 as the width of the eye ; the edges of the cup-shaped prominence being also 

 produced into two dorso-lateral horns and two ventro-lateral horns ; making a 

 total of six horns or serrations to the front. Antennae : simple in both sexes. 

 Thorax : entirely clothed with scales, without crests. Abdomen : clothed mainly 

 with scales, with a few hairs intermixed, without crests. Fore tibia : with the 

 chiten drawn-out on the outer side into a claw-like projection ; the length of the 

 tibia being slightly greater than the metatarsus or one-half of the tarsus. Pri- 

 maries : moderately trigonate, the apex rounded; veins 3, 4, 5 (CUj^, M^, M^)
