128 AMERICAN LEPIDOPTERA. 



Setagrotis dernariuiii n. sp. 



Ground color dull smoky brown, tending to more reddish-brown. Head paler 

 brown, with an admixture of white scales and a narrow black median transverse 

 line; palpi blackish at sides. Collar with two darker and two paler brown lines, 

 and whitish at tip. Thoracic disc gray; the patagia mottled with blackish scales. 

 Primaries grayish, powdered along the costal region, this powdering extended' 

 also in the basal and s. t. spaces, and somewhat along the inner margin, leaving 

 a darker longitudinal shading through the centre of the wing. The transverse 

 maculation is lost or modified to a strigate type. Tliere is a narrow blackish 

 basal streak extending to an angle of the t. a. line and beyond this an obscure 

 claviform reaches to the middle of the wing. Basal line geminate, marked by 

 oblique costal streaks only. T. a. line geminate, strongly dentate, broken, inclu- 

 ded space whitish, and this whitish included line is all that remains in the me- 

 dian cell. T. p. line marked by venular black and pale dots, on the whole paral" 

 lei with the outer margin. Veins black lined, interrupted on the t. p. line, and 

 accompanied by white shades on veins 3 and 4, so as to cut the terminal space to 

 the outer margin. No obvious s. t. line. A series of small blackish terminal 

 lunules. A pale line at the base of the dusky fringes, which, opposite the veins, 

 are narrowly cut with paler brown. The orbicular is narrow, very much elon- 

 gate, a little oblique, ringed with whitish, centred with brown. It does not quite 

 reach the reniform, which is broadly ovate, dusky, incompletely outlined. Sec- 

 ondaries whitish, with a yellowish tinge, the outer border darker and with darker 

 powdering.s on the veins; discal luuule blackish. Beneath: gray, powdery; pri- 

 maries with disc smoky, with a broad outer smoky line and a discal spot; second- 

 aries more whitish below the costal region, with a punctiform outei' line and a 

 narrow discal lunule. 



Expands 1.23-1.38 inches = 31-34 mm. 



/ra6.— California, W. D. Urban, 1906, 106 ; Easton, Washington. 



One male, the smaller example from California, was sent by Sir 

 George F. Hampsoa for identification, and is somewhat defective 

 and rubbed ; one female, the larger example from Washington was 

 probal)ly from Prof. Piper's lot, although not dated and without his 

 label ; but it is an almost perfect specimen, and from it the descrip- 

 tion was chiefly made. As already noted I had the male^^us asso- 

 ciated with this female until the specimen from the British Museum 

 furnished an exact mate to it. In this male the antennae are very 

 strongly serrated and tufted, and the spines on the anterior legs are 

 obvious. Thi.s, therefore, belongs to Lycophotia as defined by Hamp- 

 son and to which Setagrotis is referred as a synonym. For the pres- 

 ent I am not quite ready to agree to this, and therefore hold to ray 

 generic reference. 



Setagrotis diicniis n. sp. 



Ground color dull powdery luteo-fuscous. Head, except front, whitish ; palpi 

 with white intermingling hair. Collar inferiorly white, limited by a median 

 brown line, above which there are blackish scales. Thoracic vestiture defective
