Chorizagrotis boretha, new species. 



Ground color dull smoky red -brown. Head concolorous or a little paler. Collar 

 inferiorly pale, like the costal region of primaries ; this pale portion limited above 

 by a transverse black line. Thorax of the ground color, disc tending to become a 

 little paler; primaries with costal region more or less contrastingly paler, tending to 

 yellowish ; ordinary spots also discolored, yellowish. Cell black-filled before and 

 between the macula ; a black mark below median vein in basal space. Basal line 

 geminate, black, marked on costa and where it cuts the basal streak with its pale 

 filling. T. a. line geminate, black, with pale included space, incomplete, marked on 

 costa and by an excurved mark in the sub-median interspace. T. p. line geminate, 

 the outer portion tending to become lost, the inner lunulate, abruptly bent outward 

 below costa, then almost parallel with outer margin. S. t. line a little sinuate, of 

 the ground color, marked by the darker color of terminal space except at apex where 

 it is defined by a dusky preceding shade ; also preceded by a series of sagittate black 

 marks in the interspaces. A series of small black terminal lunulas and a yellow line 

 at base of fringes. Claviform moderate in size, concolorous, pointed, black margined. 

 Orbicular moderate in size, a little oblique, tending to ovate, yellowish, contrasting. 

 Reniform large, kidney-shaped, incompletely black margined, yellow with a smoky 

 central line, top and bottom tending to become infuscated. Secondaries smoky whitish 

 at base, becoming darker outwardly ; a smoky discal lunule ; fringes whitish. Beneath 

 whitish, more or less powdery, all wings with a discal spot, primaries with an indi- 

 cated outer line. 



Expands, 1. 40-1. 48 inches — 35—37 mm. 



Habitat. — Kaslo, B. C, August and September, Mr. Cockle. 



Three males and one female, none of them very good, but alto- 

 gether demonstrating a distinct species allied to terrealis Grote. 

 From the latter species the discolorous ordinary spots separate it at 

 once, the general details of maculation being otherwise much the 

 same. The single female is much more powdery in appearance than 

 any of the males, but this may not be a uniform feature. In a gen- 

 eral way the species has the appearance of perexcellens, the antennal 

 structure, however, being quite different. 



Chorizagrotis sordida, new species. 



Ground color dull sordid brown, more or less shaded with black or smoky. Head 

 concolorous. Collar concolorous, with a black median line. Thorax uniform, of the 

 ground color. Primaries withh a black diffuse streak through basal space below median 

 vein, interrupted by the basal transverse line. Cell more or less darker or even 

 blackish before and between the ordinary spots, but not solid black-filled. Basal 

 line geminate, black, included space pale, usually broken and best marked on costa 

 and through the black streak. T. a. line geminate, black, included space pale, a 

 little outwardly oblique and slightly excurved in the interspaces. T. p. line geminate, 

 the outer portion lost beyond the costal region, the inner blackish, lunulate, very even, 

 almost parallel with outer margin. S. t. line a little sinuate, concolorous, marked by 

 a dusky preceding shade on the costa and by a series of black, sagittate interspaceal
