semblance to clandestina, but the coloration and wing form are quite 

 different. The thoracic tufting is not distinct, but is well indicated, 

 the vestiture being rather loose. 



Agrotis atomaris sp. nov. — Head, thorax and primaries deep smoky or 

 blackish brown. Palpi darker at sides, collar with a tip of luteous scales, tho- 

 racic crest with an admixture of hoary scales. Primaries with a luteous shading 

 through the centre of the wing. All the maculation obscure, indistinct, yet all 

 traceable. Basal line marked on costa only by a geminate black spot. T. a. line 

 geminate, sometimes traceable through the cell, somewhat outcurved between 

 veins and with a long outcurve below the internal vein. T. p. line geminate, 

 marked on costa, evenly outcurved over reniform, inner line finely crenulate, 

 outer scarcely mai-ked, except by the slightly paler included shade. S. t. line 

 paler, interrupted, sometimes almost obsolete. Claviform present, outlined in 

 black. Orbicular round, moderate in size, very indistinctly outlined. Eeniform 

 rather large, normal in form, slightly more leaden black, not very definitely 

 outlined. Secondaries ( % ) pure white, a narrow dusky marginal line. Beneath 

 white, powdery, with an interrupted outer line and discal spot to all wings. 

 Expands 1.25 inches; 31 — 35 mm. 



Habitat. — California (Neumoegen). 



The structural characters refer this species to the pitychrous 

 group, and most nearly to vellervpennis. From this latter species 

 our form differs in the somewhat lighter shade of the wings, rather 

 more luteous than black, while the ordinary spots are not so neatly 

 outlined, and the transverse maculation is rather more distinct. 

 Three males are before me, all very much alike. There is a chance 

 that this may eventually prove identical with velleripennis, but I 

 doubt it. 



Agrotis reinota sp. nov. — General color a pale, carneous gray. Palpi 

 blackish at sides, else head and thorax immaculate, concolorous. Primaries with 

 a reddish sufl'usion apparent in the median space, and the terminal space dusky. 

 Basal line geminate, distinct, brown. T. a. line geminate, incomplete, slightly 

 outcurved in the interspaces. T. p. line indistinctly geminate, as a whole well 

 exserted over the reniform and thence rather evenly oblique to the inner mar- 

 gin ; inner part of line fine, crenulate, outer line represented by venular dots 

 distinct only below vein 5. S. t. line indefinite, irregular, forming an outward 

 curve on veins 3-5, and again near apex ; relieved by the dark terminal space. 

 Claviform small, concolorous, incompletely outlined. Ordinary spots paler ashen 

 gray; orbicular outlined in black, oblique, somewhat irregular oval. Eeniform 

 large, kidney shaped, narrowly pale lined, incompletely outlined inferiorly, out- 

 wardly with a pale, more yellowish blotch. A very narrow, interrupted, termi- 

 nal line. There is a slightly deeper shade of reddish between the ordinary spots, 

 but nothing like a distinct dark shading. Secondaries soiled whitish, with a
