By G. H. French, Carbondale, III. PSEUDAGLOSSA FORBESII, n. Sp. Similar to P. lubricalis, and probably heretofore mis- taken for that common species. In size and color more like P. scohialis, but smaller. Color dull brownish black, with very little of the lustre of P. luhricalis. T. a. line straight in its course, slightly wavy, black, preceded by a pale line; median shade forming a distinct black line, curved outward through the cell; t. p. line black, ex- tending obliquely outward from the costa to subcos- tal vein, thence nearly straight to posterior margin, slightly dentate, followed by a pale line that is very fine except on costa, where it is quite prominent ; a subcostal pale line that is obscure except on the costa, a terminal black line cut with pale between the veins; fringe dusky. The pale part is paler than in P. Viibricalis and less yel- lowish. Hind wings blackish, the basal portion pale, the lines of the fore wings, except the t. a., continuous across these but parallel to outer margin, the pale lines white and prominent ; discal spots of both wings obsolete. Un- der side gray, from a mixture of black and white scales,, the lines of upper side, except the t. a., repeated. Head and thorax above solid brownish black, the tip of joint 3 of the palpi pale; abdomen concolorous with hind wings, annulate with pale. Expanse from .70 to .75 inch; length of body .25 inch. Described from 4 females collected at Savanna, 111., in 1892, two of which were taken at sugar, and two found upon the flowers of sweet clover {Melilotus alha) by day. Three of these are in the collection of the State Laboratory of Natural History, and one is in the author's cabinet. Illinois State Laboratory of Natural Hktonj. <> Pallachira hartii, u. sp.

Hind wings smoky. Under side darker than the upper; fore wings immaculate, hind wings with a discal dot and a dusky subterminal line.
