Pzpanse, 36 to 38,m. m. Habitat, New York; Colorado Ter- 
ritory (coll. Theo. L. Mead, No. 66). 
Differs from Guenée’s description of N. ochrogaster by the 
blackish collar and the median nervure not being white; the ter- 
minal line on the primaries is succeeded by an even 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 
glass 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 fiattened, 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 4 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, Grote, Plate 3, fig. 4,0. 
¢ —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 Tn using Lederer’s analytical table, the untoothed antennae will separate the present genus 
from Ammoconia.
