of Drasteria or Euclidia. The female seems the darkest, and some- 

 times the wing appears uniformly blackish, with double pale lines 

 on the hind wings, and the subterminal jiale line alone distinct on 

 primaries. In one specimen all the lines are obsolete on both wings 

 and the anterior half of the median space is alone pale-colored on 

 the primaries. 



Tarache terminimaciilata, Grote. 



i . — Eyes naked, without lashes. Clypeal surface without projection. Tibiae 

 unarmed. Head, thorax and legs with appressed squamation. Size moderate. 

 Scutum of the thorax large and globose. The wings widen outwardly and are 

 strongly veined. The head, thorax and fore wings are pearly gray ; primaries 

 with a black point on the cell and with the terminal portion taken up by a 

 large red-brown shaded space, neatly defined inwardly by an arcuate line lined 

 inwardly with white, and which, after a short oblique outward reflection below 

 costa, sweeps inwardly roundedly to internal margin. On the dark terminal half 

 of the wing a blackish transverse line may be discerned below the outward 

 projection of the white line. This dark line is tremulous and marked with a 

 pale hair-streak at internal margin. An indistinct subterminal brown shade ; 

 the wing becoming grayish again along terminal margin. A series of black 

 terminal points ; fringes pale. Posterior wings without markings above and 

 below, silky testaceous white. Beneath without markings, primaries darker 

 shaded. The internal angle of the fore wings is slightly produced. Abdomen 

 without tufts. 



Expanse, 28 m. m. Hahitat, Albany, X. Y. (Mr. J. A. Liutner, 

 No. 1061). 



A little stouter than Tarache aprica (a species subject to great 

 variation and of which Acontia hiplaga, Guenee, is certainly only a 

 variety), and differing greatly from any of its congeners in ornamen- 

 tation and coloration. 



Tarache flavipeunis, Grote. 



2 . — Allied to T. aprica, and especially resembling that form of this species 

 described as distinct by Guenee under the name of biplaga, but differing by the 

 yellow hind wings and smaller size. The fore wings are almost entirely black- 

 ish with a larger white space at the middle on the costal region enclosing the 

 black discal point, and a smaller, marking the inception of the dotted subter- 

 minal line. There is a whitish shade on the middle of the internal margin 

 and the black dotted terminal line is concluded by a white streak at internal
