Agrotis invenusta n. s. 

 Female: Allied to Atrifrons, with the same i^imple markings. Blackish- 

 ashen; median lines single, black, indistinct, slightly relieved by pale shade, 

 and emanating from costal dots. Only the two lines can be made out. 

 Thorax blackish-ashen ; front and tips of palpi gray. Hind wings dark 

 fuscous, a litle paler on the disc, veins soiled, no lines, a discal lunule. 

 Beneath a curved black exterior line, very distinct on costal region of 

 primaries, repeated on secondaries, and followed here by a faint sub-mar- 

 ginal shade ; the discal mark on hind wings repeated. Expanse, 35 mil. 

 No. 942. This species, although obscure in appearance, should be readily 

 identified by the simple markings, and its affinity with Atrifrons, even in the 

 markings beneath, which are ])lainer than usual. The color is different — 

 the front pale, the hind wings darker than its ally. 



Ammoconia Distichoides n. s. 

 Eyes naked. Tibii:e armed. Thorax with a central ridge. Much resem- 

 bles Orfhosia Disticha, of an even, olivaceous gray. Sub-terminal line faint, 

 single, dark, starting from a black trigonate spot on costa. T. p. line punc- 

 tate. A black interrupted terminal line. Stigmata approximate coucolorous, 

 indistinct, with a reddish stain. Median shade visible below reniforra, 

 marked between them on cell, and again above reniform on costa. T. a line 

 thrice waved, single, black, marked on costal region. Thorax and head like 

 primaries. Under the glass the primaries are dotted with fine black speckles. 

 Hind wings pale fuscous, unlined, with paler fringes. Beneath, a common 

 exterior black line, marked on veins over costal region, else obliterate. 

 Discal marks. Smaller than Aratrix, to which it is nearest allied. New 

 Mexico. "940." Prof Snow. Expanse S5 mil.

 especially at costa ; a black dash at anal angle, before which the s. t. line is 

 bent and heavily marked with black. Beneath no markings; hind wings 

 white, dusted a little on costa; fore wings pale fuscous. No. 957. Expanse 

 24 mil.
