me. Front luucrouate, anterior tibite armed, median shade distinct. 

 Its closest ally is perhaps incallida, from which the simple lines sepa- 

 rate it at a glance. The legs, too, are not handed as in the other 

 species, and there are numerous other distinctive features. 



Ai^rotis incallida sp. nov.— General color pale ashen gray. Palpi brown 

 at sides ; a dusky line across tlie front; collar dark tipped. Thorax unicolored, 

 coneolorous. Primaries with slightly darker suffusion beyond the median shade. 

 Basal line geminate, black, upright, lunulate, tlie outer line liroad, tlie inner 

 narrower and fainter. A broad, black median shade, somewhat diffuse outwardly. 

 T. p line black, lunulate, geminate, the outer line distinct near costa only, a 

 strong outcurve over the reniform and a slight incurve in the suhmedian inter- 

 space. S. t. line irregular, interrupted, })ale, marked by a very distinct smoky 

 preceding, and a somewhat less evident following shade. Claviform wanting, 

 orbicular barely traceable, coneolorous ; reniform marked only by an indefinite 

 dusky spot. Secondaries deep smoky brown. Beneath very dark smoky brown, 

 with white powderings along the costa, broader on secondaries. A broad diffuse 

 outer band, distinct only through the paler parts of the wing ; secondaries with 

 a discal spot. Vestiture of breast ash-gray, tarsi and tibije l)la(k ringed. Ex- 

 pands 1.5 inches; 37 mm. 



Habitat — Sierra Nevada, Cal. 



The structural characters as far as they are ascertainable from 

 the single female before me, are like the inessoria group. The fore 

 tibi?e are spinose, the clypeus is nmcronate, and the maculation is 

 like that of extranea and frlfasciata, from which the color and the 

 want of distinct ordinary spots separate this species. The appear- 

 ance and habitus at first refer to opipera., munis and dissona, but all 

 of these afford distinctive characters, leaving the color and general 

 appearance responsible for the impression. It is perhaps closer to 

 the Alpine simjjlonia than any of our own species. 



Agrotis lutuleiita sp. nov. — (ieneral color a luteous gray ; sides of palpi 

 dusky, a dusky line extending from the eyes to the base of primaries; head and 

 tliorax else immaculate. Primaries slightly blackish powdered, more distinct 

 along the inner margin, and darkening the terminal and outer part of s. t. space. 

 Basal line geminate, not well marked. T. a. line geminate, outwardly slightly 

 oblique, moderately outcurved in the interspaces, a long outcurve below internal 

 vein ; inner part of line obsolete, outer very distinct. T. p. line narrow, crenu- 

 lated, parallel with the outer margin, inferiorly becoming indefinite; outer part 

 of line marked only near costa and not continued as a series of venular dots. 

 Median shade indefinite, diffuse, best marked between the ordinary spots, and 

 with some difficulty traceable below. Beyond the t. p. line the s. t. space darkens 

 to the outer margin interrupted by the very fine, pale, irregular and partly ob- 

 solete s. t. line. No dark terminal line or lunules, a pale yellow line at base of 

 fringes. Claviform wanting. Orbicular round, pale ringed, not prominent, 

 scarcely even distinct. Reniform large, very vague, not outlined, marked by a 

 yellowish curved line, which constitutes the outer margining line, and by a
