color, and the lack of the distinct contrast between the median space 

 and the basal and s. t. spaces. The orbicular is as in rufula, but the 

 underside is much darker, with the maculation not marked. 



Two specimens, S and 9 '^i"e before me, differing very decidedly 

 in appearance. The male is paler, the maculation more distinct, and 

 the pallor of the basal space is more evident. The female is darker 

 throughout, the tendency along the costa and in the ordinary spots 

 to a cinereous powdering, the contrast between basal and median 

 space not well marked. The species is not a strongly marked one, 

 but is distinct, I think ; though most difficult to separate from the 

 species above named, it really gives the impression, in the 9 more 

 especially, of tessellata. It cannot well be that species, however, 

 variable as it is ; the structural characters are like tessellata throughout. 



Agrotis reiia sp. nov. — General color varies from a very pale carneous gray 

 to a distinct reddish gray, the change being rather one of intensity than color. 

 Head and thorax immaculate, palpi dark at sides. Primaries with the macula- 

 tion not strongly contrasting, transverse lines sometimes obsolete; in fully 

 marked specimens basal line distinct, geminate, black ; t. a. line very slightly 

 outcurved, irregular, geminate, outer line blackish, broad, distinct, inner line 

 faint and more even. T. p. line geminate, outer line punctiform, inner line 

 narrovsf, crenulated, its course rather even, and not strongly outcurved over 

 reniform ; s. t. line pale, narrow, very slightly irregular, relieved by a distinct, 

 dark, rather narrow, preceding shade. A narrow interrupted dark terminal line. 

 This maculation may be wanting in part or entirely; one specimen lacks all but 

 the merest trace of the t. p. line; usually the s. t. line I'emains distinct. Clavi- 

 form small, incompletely outlined, in pale specimens entirely wanting. Orbicu- 

 lar large, round, slightly irregular, narrowly pale ringed, a black spot filling the 

 space between orbicular and t. a. line, and another dusky shade filling the in- 

 terval to the reniform the color of the included space is very slightly paler than 

 ground color; reniform large, upright, kidney shaped, narrowly outlined in pale, 

 with a leaden gray filling becoming blackish inferiorly. These ordinary spots 

 are constant in the series examined though the distinctness varies, as does also 

 the color of the filling between them. Secondaries soiled white to pale fuscous, 

 the difference not sexual. Beneath, primaries fuscous powdery, pale at costa, 

 with an outer transverse line visible only at costa, and a large discal spot; sec- 

 ondaries much paler, powdery, with a distinct outer shade line and large discal 

 spot. Expands 1.25— 1.32 inches; 31— 33 mm. 



Habitat. — Sierra Nevada, Cal. (McGlashan). 



The series before me, by the kindness of Mr. Edwards, shows 

 quite a long range of variation within comparatively narrow limits. 

 There is little or no change in ground color nor in the relative posi- 

 tion or course of the lines or spots, while the whole transverse macu- 

 lation may be almost completely gone and only the ordinary spots 

 remain. In structure it fully agrees with tessellata and declarata, and
