Mamestra acutipennis, n. s. 



This is a species with rather long wings, having the external margin 

 quite oblique. It is nearer, perhaps, to vidua than any other species. 

 The wings are blackish gray and with the median space shaded with black. 

 The markings and lines are inconspicuous. The median lines approach 

 on submedian fold. The orbicular is ovate, oblique, paler gray, with 

 black central streak. Reniform similar, upright, rather narrow and small. 

 Subterminal line pale, with a projection over m. nervules, without teeth ; 

 it forms the usual more prominent white mark relieved by black scales 

 above internal angle. Secondaries diaphanous white at base with discal 

 point and broad diffuse blackish borders. Thorax blackish. A black 

 line on collar. Beneath the hind wings are whitish at base, powdered 

 with blackish exteriorly, with a discal dot and mesial line. Exp. 30 mil. 

 Nevada, Dr. Bailey. 



Hadea a cylindrica, n. s. 



A small bodied and rather large winged species of a dusty gray, with 

 obliterate lines. The orbicular pale gray, rather large, slightly oblique. 

 The reniform large, blackish gray, with blackish centre, relieved by black- 

 ish shading. Subterminal line pale, indeterminate, straighter than usual, 

 preceded by a brownish shading over the median nervules. Veins marked 

 in blackish, dotted with white in place of posterior line or behind it. A 

 fine, black, interrupted terminal line. Fringes gray, narrowly cut with 

 paler, and finely interlined. Hind wings yellowish gray, unicolorous, 

 paler beneath, from whence they reflect a mesial line and dot. Fringes 

 whitish ; beneath preceded by a black broken line. On primaries above 

 the s. t. line issues from an ill-defined pale apical shading. Thorax like 

 fore wings ; abdomen colored like hind wings. Eyes naked. Abdomen 

 without tufts except at base. Tibiae unarmed. Expanse 25 mil. Nevada, 

 Dr. Bailey. 



Hadena totisa, n. s. 



A small blackish gray species resembling somewhat the vicina group 

 of Mamestra, but with naked eyes, and with the subterminal line forming 

 three curves, the widest over the median nervules at the place of the usual 

 W-mark, which latter is usually more prominent in Mamestra than in 

 Hadena. The median lines uneven, propinquitous, narrowing the median 

 space, especially inferiorly, and shaded with black from the diffuse median 

 shade. Reniform well-sized with double black annulus enclosing a white
