out abdomen, but else in good condition; the other is from Mr. Thomas 

 Spalding and in good shape. This differs from the other described species, 

 all of which are represented in my collection by the distinct and rather even 

 red-brown, and the well-marked median lines. It is perhaps nearest to 

 satyricus in type of maculation, but differs obviously in color, in the absence 

 of all trace of ordinary spots, and in the immaculate under side. 



Mamestra leomegra nov. sp. 



Ground-color blue-gray shaded with smoky, powdered and ornamented with 

 black. Head with a black line across front. Collar with a black line across middle, 

 dividing the smoky lower from the ashen upper portion. Thorax mottled with 

 blue-gray, smoky, white and black, forming no distinct markings. Primaries with 

 all the maculation obvious, but so obscured and mottled that scarcely any of it is 

 clear-cut and distinct; the narrow yellowish s.t. line with the prominent black 

 preceding shades forming the most conspicuous feature of the wing. Basal line 

 geminate, black, broken, the whitish included space broad and most obvious; a 

 pair of curved black marks just below the median vein. T.a. line geminate, black- 

 ish, oblique, outcurved in the interspaces; included space broad, pale. T.p. line 

 geminate, lunulate, a little irregular, broadly exserted over the cell and a little 

 incurved below; included space narrower and not so pale as in t.a. line. There is 

 an obscure, diffuse, smoky median shade, which darkens the outer part of the median 

 space. S.t. line forms a small W on veins 3 and 4, where the preceding black shad- 

 ing is less conspicuous than it is above and below. A series of conspicuous black 

 terminal lunules. Claviform small, concolorous, black-margined. Orbicular, of 

 good size, broadly and irregularly ovate, oblique, black-margined, a little lighter 

 than the ground, with a smoky center. Reniform large, lunate, black-edged, out- 

 wardly with a margin of white scales wthin the black, center smoky, inclosing a 

 curved gray streak. Secondaries blackish, the outer margin narrowly gray. Be- 

 neath, gray, powdery; both wings with a conspicuous black discal mark and a more 

 or less evident extra-median line. The primaries have a narrow whitish outer 

 border, and in the female this is obvious on the secondaries as well. 



Expands 1.90-2.00 in. = 47-50 mm. 



Habitat: Grand Lake, N.F., Aug. 28. 



Three males and one female, of which only one female is in really good 

 condition. The specimens were caught at light by Mr. Owen Bryant, 

 packed dry in cotton, and sent me through Mr. C. W. Johnson of the Boston 

 Society of Natural History. The species is obviously related to imbrifera, 

 but is larger and darker throughout, and distinctly more blue-gray in color. 

 The W of the s.t. line, while small, is distinct. The antennpe of the male 

 have the joints only a little marked, with little tufts of fine bristles and longer 

 single cilise. The tuftings appear to be as in imbrifera, but less developed.
