line punctiform. S. t. line pale, very slightly less so than ground color, relieved 

 by a dusky preceding line, and a general dusky coloring of the terminal space; 

 its course very slightly irregular. In the reddish forms the transverse lines are 

 almost entirely obsolete. Claviform wanting. Ordinary spots evenly dark 

 filled, with a narrow defining line, small iu size. Orbicular slightly oval, oblique ; 

 reniform rather narrow, upright, very slightly constricted. Secondaries glis- 

 tening, smoky fuscous, somewhat paler basally. Beneath pale, powdery fuscous, 

 with a darker outer line and discal spot. Expands 1.36 — 1.50 inches ; 34—37 mm. 



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



This species is very distinct from any other known to me by the 

 peculiar association of structural characters, combining the habitus 

 of the cupida group with the antennae, but not frontal characteris- 

 tics of the pityckrous section, and peculiar and different from all by 

 the distinct ridge or crest to the thorax. In this feature it resem- 

 bles Gkea or allies, but the form is not depressed. It will probably 

 form a new generic type characterized by smooth front, palpi with 

 second joint clavate, third joint minute, forming a short snout with 

 the frontal vestiture ; anterior tibia unarmed, middle and posterior 

 spinose, thorax with vestiture smooth, consisting of flattened hair 

 and scales, with a distinct crest anteriorly. The genital structure is 

 not unlike that of the cupida group, and the insect is not unlike 

 cupidissima in character. The thoracic crest is perfect in but one 

 specimen before me. 



Types are in collection Rutgers College, coll. Hy. Edwards, and 



coll. B, Neumoegen. 



Agrotis plaiiifroiis sp. nov. — General color a bluish ash-gray : sides of 

 palpi blackish ; collar black tipped ; thorax immaculate. Primaries with a dis- 

 tinct vinous red shade through the lower half of the wing, less marked in the 

 basal and terminal spaces. Basal line single, black, strongly dentate, running to 

 the basal dash. T. a. line single, broader on costa and internal margin, strongly 

 dentate between veins, slightly oblique outwardly. T. p. line broad, distinct, 

 crenulate, outwardly curved over reniform, and inwardly sinuate below, the 

 curves very even and not strong. A broad, ditfuse, median shade crosses the 

 reniform, then runs parallel and rather close to t. p. line, darkening the median 

 space beyond, to the t. p. line. S. t. space becoming gradually darker to the 

 s. t. line, which is defined and limited only by the contrast of this dark shade 

 against the concolorous terminal space. A row of black terminal lunules. A 

 black longitudinal dash at base extending to t. a. line. Claviform wanting. 

 Orbicular concolorous, black ringed, elongate, the ends drawn out, the one reach- 

 ing the t. a. line the other to the reniform, which is narrow, binate, incompletely 

 defined, darkened by the transverse median shade. Secondaries white, veins a 

 trifle soiled, and with a dirty indefinitely marked outer border. Beneath, pri- 

 maries fuscous, powdery, paler costally where the outer transverse line is visible ; 

 secondaries paler, more powdery, with outer line marked across costal space only ; 

 a distinct discal spot. Expands 1.37 inches; 34 mm. 



Habitat — N. W. British Columbia.
