CHIONOBAS I. 
pale gray-brown; cell slightly flecked with brown next sub-costal nervure; the 
discoidal ocellus repeated, and also that on second median interspace when present 
above. 
Secondaries white on costal margin, the remainder of wing dead-leaf brown 
upon a white ground, the sub-color appearing most distinctly next beyond cell, 
along median nervules and over abdominal margin; the whole surface covered 
by flue, abbreviated, brown streaks, least densely on costal margin, most next 
base and over sub-median interspace, and for a broad space along hind margin; 
a white point next the margin on the middle of each interspace; the ocellus, 
" hen present above, repeated; and in a line with this, a series of white points, 
one on each interspace across the wing to costa — representing, perhaps, obsolete 
ocelli, which might sometimes be found more or less complete; the disk crossed 
Irom margin to margin by a broad, irregular band, narrowly edged on either 
side by a blackish-brown border; the space within the band not differing in 
shades of color from that beyond; the exterior border commences on costa'just 
above outer angle in a wedge-shaped spot which reaches the second discoidal 
nervule, then continues by a single curve, convex outwardly, to upper branch 
of median, at which point it curves outward again to the middle of the adjoining 
interspace, and continues in a line nearly straight almost to lower branch'of me°- 
dian, then obliquely forward till it strikes this branch, from which it proceeds in 
a straight line to margin; this outline may be briefly described as composed of a 
straight line, a single curve, a square offset, and a straight line to margin, and 
is quite unlike the scolloped outline of the similar band in the nearest allied 
species, Gigas ; the outline of the basal side is that of a double curve, at first 
convex towards base of wing, and most advanced on sub-costal nervure, then 
returning, the extreme concavity being on median, opposite the beginning of the 
line on costa. 
Body blackish-brown above, black beneath, the abdomen gray-brown; leo-s 
black, the tibiae gray-brown; palpi black with gray hairs interspersed; antemfte 
brown, beneath gray ; club dull ferruginous, gray beneath. 
Female. —Expands 2.6 inches. 
I pper side paler than in the male, fading beyond the disk into buff; the 
oblique band wanting; base of cell on primaries, and that portion of cell next 
sub-costal nervure brown ; primaries have two large ocelli, the upper one pupil- 
lated, the lower one sometimes blind, and one or both accompanied by a small 
blind ocellus on the interspaces next preceding; secondaries marked as in the 
male. Under side of both wings paler than in the male ; the outlines of the band 
similar.
