CHIONOBAS IVALLDA, 1—5. 
Chionobas Ivallda, Mead, Can. Ent., X., p. 196, 1878. 
Male. — Expands from 1.8 to 2.3 inches. 
Upper side of primaries blackish-brown, varying in individuals from dark to 
pale; the costal margins finely and transversely streaked gray and brown; the 
hind margins narrowly edged with brown; on the lower side of cell and partly 
within it a black sexual band, sometimes obsolescent; between the nervules a 
series of elongated gray-ochraceous spots, nearly or quite filling the inter¬ 
spaces, usually six in number; but sometimes the uppermost one is wanting; 
in one example examined there is no trace of these spots (Fig. 5); on the second 
spot from costa is a black ocellus, always small, sometimes minute, with white 
pupil; and in about one fourth the examples there is a minute spot on the 
lower median interspace, rarely large enough to admit a pupil. 
Secondaries gray-ochraceous, edged with brown; in submedian interspace is 
usually a small pupilled ocellus ; fringes brown at the ends of the nervules, white 
in the interspaces. 
Under side of primaries gray-ochraceous, the costa black and white; the upper 
part of cell streaked transversely with brown, — sometimes the entire cell; about 
three fifths the distance from base to arc some ol these streaks become confluent 
and form a sinuous bar; the disk is crossed by a brown stripe, which projects a 
long tooth upon upper branch of median; below this the stripe is twice roundly 
incised, and sometimes projects a spur along the sub-median interspace nearly or 
quite to the hind margin; the apical area finely streaked with brown on white 
ground; the ocelli repeated. 
Under side of secondaries whitish, with an ochraceous tint over the disk and 
marginal area; much covered with dark brown abbreviated streaks, which at 
base and on middle of disk are largely confluent; the wing crossed by a broad 
mesial band, the edges of which are dark, the outer irregularly crenated or
