line. The fringes are white beneath, both wings \vhiti.sh toward the base, with a 

 broad, smoky outer border ; the secondaries in addition with a smoky extra-median 

 line, a trace of which is also seen on the primaries. Expanse, 1. 20 inches = 30 mm. 



Habitat : Foothills near Denver, Colorada (Bruce). 



The type is a female which has been in my possession for a long 

 time awaiting the advent of a male. None has been received ; but as 

 the species seems very distinct I have given it a name. It may be as- 

 sociated with lioDwgcua, although it is much less sharply marked than 

 that s])ecies. 



Oncocnemis corusca, sp. nov. 



Head, thorax and primaries blackish, more or less mixed with white scales. 

 Head pale powdered, below the vertex more evenly blackish. Thorax without dis- 

 tinct tufting, the scales tipping collar and patagice w^hite. Primaries veiy dark to the 

 t. p. line with the markings veiy obscurely marked ; the vestiture a little glistening. 

 Basal line marked with gray, and the extreme base of the wing is Cjuite strongly 

 powdered with similar scales. The t. a. line is hardly traceable ; but its position is 

 indicated by gray scales. T. p. line white, very obscurely marked to vein 4 ; bu 

 below that point easily traceable through the blackish ground color. S. t. line white, 

 distinct only near the hind angle. The orbicular is small, round, defined by a whitish 

 ring. Reniform moderate in size, kidney-shaped, whitish with a smoky curved line, 

 and from this point begins a whitish powdering that obscures the outer margin of the 

 reniform as well as the upper jiart of the t. p. line. There is a series of obscure dark 

 terminal lunules. The abdomen is yellowish. Secondaries orange yellow, with a 

 well-defined moderate black outer border; the fringes white. Beneath, primaries 

 smoky, with a yellowish tinge, without obvious markings. Secondaries yellow, with 

 a blackish outer border and a blackish shading in the costal region. Expanse, 1. 08 

 inches ^= 27 mm. 



Habitat: Los Angeles, California; Yosemite, California. 



I have two male specimens of this species, one of them received 

 from Mr. H. G. Dyar and numbered 9040, taken by Lembert in the 

 Yosemite Valley, the other taken by myself. The species differs ob- 

 viously from the other yellow winged species of Oncocnemis by the ob- 

 scure marking of the primaries and the somewhat glistening vestiture. 

 In all the other species the markings are quite sharply defined. 



Scotogramma Smith. 



The species of this genus are increasing in number and several un- 

 described forms occur in collections. Five of these are in sufficient 

 numbers to warrant description. Plve species were recognized in 

 1889 and differen*:iated in Vol. XII, Proc. U. S. Nat. Mus., p. 462. 

 Of these I knew the male of one species only. Three species have 

 been since described, but the sexual characters have not been figured.
