CHIONOBAS II. 
returning, presenting a deep square sinus on median nervure, after which its 
course is wavy to the sub-median nervure, where it terminates: the ocellus 
repeated. 
Body blackish-brown above, black beneath, the abdomen brown; legs and 
palpi black; antennae brown, gray beneath; club dull ferruginous, gray beneath. 
Female. — Expands 2.5 inches. 
I pper side of a deeper color than the male, alike on both wings, with broader 
and blacker marginal borders; costa of primaries brown, gray next apex- the 
oblique discal band wanting; the two principal ocelli larger and pupillated’ and 
m addition to these, a third, blind, on sub-median interspace; the ocellus on 
secondaries as m male. Under side more distinctly marked than in male • apex 
of primaries ashy-wlnte, the marginal border gray-brown; the lar^e ocelli 
repeated, the pupils conspicuous; the third ocellus represented by °a point 
Secondaries whitish over larger part of disk, washed with brown beyond the 
band, the color deepening toward hind margin; the whole wing streaked and 
specked with brown; the outlines of the discal band distinct; the ocellus obsolete 
except the white pupil. 
From California, and described by Dr. Boisduval as found, according to Lor- 
qum, whom the four examples in his collection were received, “on hmh 
mountains, next the snow linebut on what mountains or in what section of 
the State is not mentioned. Dr. Boisduval presented Mr. Scudder with one of 
the males and myself with the corresponding female, and from these the draw¬ 
ings on the Plate have been made. Mr. Scudder informs me that the four were 
inspected by himself in Paris, and that they were alike in color and markings. 
lie species differs noticeably from Iduna and Giyas in color, being darker, and 
ot uniform shade on both wings, and nearly so in both sexes. In shape of the 
wings, it most resembles Gigas. On the under side the male is nearly des¬ 
titute of markings; the female is distinctly marked, and shows much more white 
and less density of brown streaking than Gigas, in this respect approaching 
Iduna. The exterior outline of the discal band is scalloped, but not so regie 
larly as in Giyas. In that species the general course of the outline is parallel 
to t le hind margin; in California the parallelism is broken by the prominent 
dentations on the two upper median interspaces. The course of the interior 
outline of the band differs from that of Iduna, which presents a double curve 
in that it is m the form of a single prominent curve, followed by a deep sinus 
and a wavy line beyond to inner margin. From the interior outline of the band 
on Giyas it differs in nearly the same degree. Nevadensis, Felder, is only 
known to me from the description in the “ Voyage of the Novara,” and the 
accompanying figures of upper and under side of the male. The shade is
