Expanse, 36 to 38, m. m. Habitat, New York ; Colonido Ter- 

 ritory (coll. Theo. L. Mead, No. GO). 



Differs from Gnenee's description of N. ocliroguster by the 

 blackish collar and the median nervnre not being white ; the ter- 

 minal line on the primaries is succeeded by an ev^en pale line, the 

 base of the dark fringes. The hind wings have no terminal series 

 of rounded dots. It is, I think, nearer allied to A. herilis and A. 

 subgothica. 



Ufeus, n. g. 



Ocelli. Eyes very small, naked, with lashes. Head comparatively small and 

 sunken. Maxillae weak and comparatively short. Labial palpi short, apical 

 joint undistinguishable by reason of the long and coarse hairy vestiture. 

 Middle and hind tibiae spinose ; fore tibiae unarmed, with a slight tuft at the 

 middle of the joint ; tarsi thickly spined. $ Antennae simple, under the 

 gl^ss showing two pair of fine short bristles on each joint. Head and thorax 

 thickly clothed with long hairs, recalling Euthisanotia, but here the thoracic 

 vestiture is silky, longer and more appressed. Body flattened, recalling 

 Orthosia ; sides of the abdomen with long hairs, and the anal segment is 

 densely pilose. Armature of the legs weak and short ; hind tibiae with two 

 pair, and middle tibiae with one terminal pair of aborted spurs. Legs 

 coarsely fringed with long hair like that on the body beneath. The vestiture 

 is unlike that of the $ Leucania pseudargyria, not surrounding the joints. 

 The genus appears related to Agrotis, and the type, U. satyricus, has a 

 peculiar Blatta-like appearance from its flattened form, simple antennae, 

 dark color, want of ornamentation, rather coarse and thin alar squamation, 

 and rounded external margin of primaries with blunted apices.* 



Ufeus satyricus, Orote, Plate 3, fig. 4, 5 . 



9 . — Dark dull wood brown, unicolorous. Tongue bright testaceous. Fore 

 wings with a faint tracing of an irregular, diffuse, darker-shaded transverse 

 anterior line. An undefined blackish mark takes the place of the reniform. 

 Transverse posterior line a little more distinct than the t. a. line, nearly even, 

 not much projected, perpendicular and slightly indented opposite the cell. The 

 transverse lines have the effect of darker shadows thrown across the wing. 

 No subterminal line. A series of interspaceal blackish terminal streaks of 

 variable distinctness and length. Hind wings pale, somewhat dirty testa- 

 ceous in hue, subhyaline, allowing the veins to be distinctly seen, without 



2 In using Lederer's analytical table, the untoothed antennae will separate the present genus 

 from Ammoconia.
