line. Antennae pale at base. Beneath with common line indented op- 

 posite cell on secondaries, which show a faint discal cloud-spot. Thorax 

 broM'n. U^xpansion, 3G to 40 millimetres. Albany [Professor Lintner, a 

 number of specimens; also, from Br. Bailey, 'So. 64). Seems to differ 

 from dilueida by the pale reniform and rounded orbicular; varies in 

 depth of color. I am indebted to Mr. Thaxter for an opportunity of 

 seeing Mr. Morrison's type. The t. a. line is outwardly oblique on costa, 

 as in badicollis. I do not think the discal shading a specific character. 

 The collar seems to want the narrow line of badicollis.

I have seen the type from Mr. Thaxter's collection. It seems to differ 

 from badicollis in its larger size and the want of the light brown collar ; 

 the ordinary spots are farther apart and the orbicular more rounded and 

 less elongate. Specimens are before me also from Albany, N. Y. [Br. 

 Bailey and Mr. Hill). The " male specimen", in which "the reniform is 

 white and contrasting ", probably belongs to janualis. The small orbi- 

 cular is distinctive of janualis as compared with badicollis or dilucida. 



Agrotis opacifrons, n. sp. 



$ 9 . — ^AU the tibiae spinose. Male antennae pectinate. Front black, 

 discolorous. Brownish-gray, very similar in appearance to dilucida, 

 but more reddish-brown in tint. CoJlar and thorax concolorous, un- 

 lined. Palpi wholly brownish. Lines blackish, fragmentary, marked 

 on costa. Stigmata concolorous, orbicular preceded and followed by 

 blackish-brown shading on cell ; claviform obsolete. Wings concolor- 

 ous. Posterior line denticulate. The female has the orbicular large 

 and open to costa, the male smaller and nearly closed ; in both, the 

 spot is oblique ; reniform moderate. Hind wings fuscous in both sexes, 

 with pale fringe ; the discal lunule is marked. Beneath yellowish -fus- 

 cous, in the female shaded with reddish ; discal marks and obliterate 

 common line. Expansion, 38 millimetres. Centre, N. Y., August ( W. 

 W. Hill, esq.). 



Agrotis apposita, n. sp. 



$. — Fore tibiae unarmed. Of a burnt umber brown; thorax darker. 

 Median space narrowed, the median lines approximate ; t. a. line slightly 

 lobed, outwardly oblique, dark brown, with a broad preceding pale shade ; 

 t. p. line indistinct, narrow, indented opposite the cell, slightly lunulate, 

 followed by a pale shade ; the median space paler than the rest of the 

 wing. Orbicular rounded, moderate, with faint black annulus,*stained 

 with reddish, and pale ; reniform near t. p. line, moderate, with dark 

 and reddish-stained centre and pale border. Median shade dark and 

 diffuse; claviform obsolete. Fringes concolorous; s. t. line fine and 

 pale. Hind wings dark fuscous, with pale fringes. Beneath pale, with 

 reddish tinge, irrorate; a faint common mesial line near the discal dots,
