line marked by obscure brown spots preceded and emphasized by black scales which 

 may form a somewhat continuous shade and may break up into somewhat trigonate 

 spots. There is a narrow black terminal line, the fringes are interlined with black 

 and they are cut with black and yellowish brown. The orbicular is small, round, 

 ringed by black scales, with or without a black central dot, filled with reddish brown. 

 Reniform moderate in size, oval, outer half white, inner half reddish, the division 

 between the two marked by black scales. The claviform is vaguely indicated by 

 black scales. Secondaries dirty whitish at base, darkening to a smoky outer border. 

 Fringes pinkish with a smoky line at base and smoky shadings toward apex. Be- 

 neath dull gray, primaries darker as a whole, on both the costal and outer margins 

 darker, and on both a small blackish discal spot. 



Expands. — 1.10-1.16 inches = 27-29 mm. 



Habitat. — Palmerly, Cochise Co., Ariz., in July; Brooklyn In- 

 stitute. 



Two males and others in collections from the same general locality. 

 The species is related to three Mexican species referred to Eriopyga 

 by Hampson ; but is obviously distinct from either. The antennae 

 are lengthily pectinated, and this character combined with the white 

 marked reniform will serve to distinguish the new form in our fauna. 



Genus URSOGASTRA, new. 



Head moderate in size, distinct, yet hardly prominent ; eyes hairy, globose, of 

 good size ; front smooth ; scarcely even bulging ; antenna in male simple and in the 

 female probably so ; tongue well developed, functional ; palpi small and weak, 

 scarcely attaining the middle of front ; vestiture even, composed mostly of projecting 

 flattened hair. Thorax moderate, convex, collar well defined, patagia hardly re- 

 lieved, a small posterior tuft ; vestiture, flattened hair only without admixture of dis- 

 tinct scales ; leg-, unarmed except by the usual spurs of middle and posterior pair, 

 somewhat aborted and set with very dense brushes of thick hair so as to conceal the 

 parts effectively. Abdomen without dorsal tufts ; in the male the 4th, 5th, 6th and 7th 

 segments furnished with lateral tufts of long hair which curve down and under, 

 meeting on the median line of the venter ; long brushes of specialized scales are also 

 attached to the male clasping organs. The primaries are proportionate, only a little 

 wider outwardly, venation apparently normal ; on the cell beneath, in the male, a 

 clothing of fine silky hair similar to that found in Orthodes. Secondaries with vein 

 5 reduced to a mere fold. 



This genus is based on the peculiar combination of male charac- 

 ters and would come under Eriopyga Hampson and nearest to his sec- 

 tion C, none of the species of which are cited as typical of discarded 

 genera. I cpiite appreciate that this proposed name would find a rest- 

 ing place in the synonymy if secondary sexual characters are ignored ; 

 but I am scarcely ready to go so far at present. 



As to the species here described, it is very strongly marked and I 

 can find nothing among the descriptions to fit it.
