GEOTE ON NOCTUIDS. 175 



AGROTIS ALBALIS, M. sp. 



?. — All the tibise spiDose. Appears to belong to the group of silens 

 and lagena (two specimens of this latter from Nevada are sent in the 

 present collection), but it is whiter, and all ornamentation is obsolete. 

 Fore wings gray, white over dusky. There are patches before the sub- 

 terminal line, as in milleri, but the line is more dentate and deeply in- 

 dented opposite the cell. Median lines lost. Stigmata barely indicated. 

 At the place of the orbicular is an ochrey-stained, small spot, v-shaped, 

 finely bordered with black; the apex turned to the base of the wing, 

 and apparently connected exteriorly by an ochrey-white shading on the 

 cell with the small, upright, whitish-ringed reniform. Fringes check- 

 ered gray and whitish. Hind wings whitish, with a very faint terminal, 

 smoky shading; fringes white, with a nearly obsolete, dotted interlining. 

 Head and thorax gray; abdomen whitish. Beneath white, sprinkled 

 with dark scales, without markings. Expansion, 37 millimetres, Ne- 

 vada {Dr. Bailey). The lines on primaries are barely indicated, appear- 

 ing even, not dotted. A faint white, basal, submedian streak. 



Agrotts mimallonis, Grote. 



This is one of our handsomest species. The lines on primaries are 

 variably distinct. Dr. Bailey has sent me the female from Centre, N. 

 Y. It has the hind wings white as in the male, but there is a smoky 

 border to them, more or less well defined. In the Western species 

 gagates, the hind wings are all smoky, subpellucid in the female; the 

 primaries are more obscurely colored, and, while the ornamentation is 

 similar, the subterminal line is distinctly pale, powdery, and irregular 

 in the Colorado form. 



AGROTIS CAMPESTRIS, Grote. 



I have both sexes of albipennis, which seems distinct from this form. 

 Dr. Bailey, of Albany, has sent me an interesting series of campestris, 

 varying from bright brown to black. For the distinction between this 

 species and decolor, I refer the student to the Bulletin of the Buffalo So- 

 ciety of Natural History, vol. 3, No. 5. 



AGROTIS FISHII, n. sp. 



<? ?. — In color and appearance resembling janualis, but the tibiae are 

 all spinose. Obscure purple gray. The orbicular obsolete. Lines fine, 

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

 small, sub-equal projections on cell and below costa. Median shade out- 

 wardly 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, preced- 

 ing shade at its inception on costa, interrupted, forming two marks op- 

 posite the cell very slightly margined outwardly with greenish- white. 

 A terminal black line almost continuous. Hind wings fuscous with 

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