fine, black, single, dentate. Half line visible. T. a. line erect, with 

 two small subequal projections on cell and below costa. Median sbade 

 outwardly oblique, running to lower extremity of reniform ; this latter 

 is moderate, and filled in with greenish-white scales. T. p. line dentate, 

 forming points on the veins. Subterminal line with a blackish, pre- 

 ceding shade at its inception on costa, interrupted, forming two marks 

 opposite the cell very slightly m.argiued outwardly with greenish white. 

 A terminal black line almost continuous. Hind wings fuscous with red- 

 dish fringes. Thorax concolorous purple gray ; no line on collar. Be- 

 neath body and legs obscure purplish, abdomen reddish. Wings red- 

 dish, fuscous with common dark shade line, and discal marks equally 

 distinct. Oldtown, Maine (Mr. Charles Fish). Tha primaries are more 

 pointed at apices than in janualis. The dark shade before s. t. line and 

 obsolete orbicular are strong characters. The male antenme are pyra- 

 midal-toothed, ciliatej hind wings pale fuscous."

Mr. Grote has associated the species with baja in the check-list; but 

 the structure of antenntB will hardly suffer it to remain there. Yet we 

 are unable at present to assign a certain position to it. It seems in 

 some respect, i. e., the single lines, allied to the carnea group ; but very 

 different from any species known to me. 



Somewhere I have seen a specimen named fisMi by Mr. Grote, and 

 this was very like catherina Grt. I do not find that I made any note 

 of it, however. 



Agrotis tenuicula Morr.

" Habitus and markings of Agr. conflua Tr., from which it differs in 

 the uniform gray color of the posterior wings, the presence of two dis- 

 tinct cuneiform markings before the subterminal line and below the 

 costa, and in the size of the subterminal space which is much wider 

 than in conflua.''^

The chances are that this is a form of perconjlua Grt., but I am not pre- 

 pared to make the reference definitely. I have no idea who could have 

 furnished the type of the species and have never seen any specimens 



so named.
