270 REVISION OF MAMESTRA SMITH, 



nervules. Claviform merely outliDed. Median shade line ferruginous 

 below the reuiform. Subterminal line nearly straight, a series of in- 

 terspaceal cuneiform ferruginous spots surmounted by pale atoms. 

 Hind wings dark fuscous, with pale fringes. Beneath, thickly jiow- 

 dered with blackish, with a slight ruddy stain. Hind wings, with dot

"Expanse 40'"'". 



" From the White Mountains, New Hampshire. Collected by Mr. 

 Geo. Dimmock, for whom I name the species." 



I have already explained how I came to erroneously identify this 

 species, and have named desperaia the form heretofore named dinunocki 

 by me in divers collections, including that of the U. S. National 

 Museum. As above described, I have not yet recognized the species.

" $ . 35'""\ The smallest of the genus {i. e., Aplecta). Wings slightly 

 elongate, the primaries nearly entire, rather wide, of a grayish white, 

 much powdered with blackish, which makes them griseous, except the 

 edges of the lines and the two ordinary spots, which remain white and 

 empty. The latter are very regular. The orbicular longitudinally 

 ovate. The three first lines very distinct, dentate, black ; the t. p. 

 line sending a sharper tooth in the sinus of the reniform. The sub- 

 terminal very nebulous, pale, margined anteriorly by a vague shade of 

 pale ferruginous ; the upper edge of the claviform alone visible. The 

 two median spots separated by a dark spot surrounded by black. A 

 basal ray crosses the half-line. Secondaries dirty yellowish white, 

 with traces of a discal spot, of a much-twisted median line, and of a 

 subanal blackish spot. Terminal marks thick, contiguous, and better 

 marked. Beneath, with the si)ot and line well indicated, blackish, 

 thick, the line continuous on the primaries. Abdomen short, with 

 small crests. Palpi ascending, slighter than in the other species {i. e., 

 of Aplecta).'''' 



The description is copied from Mr. Grote's translation, which I have 

 compared and which is ver^' close indeed. Judging from the figure 

 and description, the species is not a Mamestra at all, but is almost 

 certainly Agrotls trabalis Grt. I have no specimen of the latter for 

 comparison at present, but I am convinced that this was the species 

 intended by Guenee.
