CHIONOBAS II. 



returning, presenting a deep square sinus on median norvure, after which its 

 course is wavj 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. 



Upper 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 

 in addition to these, a third, blind, on sub-median interspace ; the ocellus on 

 secondaries as in male. Under side more distinctly marked than in male ; apex 

 of primaries ashy-white, the marginal border gray-brown ; the large ocelli 

 repeated, the pupils conspicuous ; the third ocellus represented by a point. 

 Secondaries whitish over larger ])avt 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 jjupil. 



From CaUfornia, and described by Dr. Boisduval as found, according to Lor- 

 quin, from whom the four examples in his collection were received, " on high 

 mountains, next the snow line ;" but 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. 

 The species differs noticeably from Iduim and G'tgas in color, being darker, and 

 of uniform shade on both wings, and neaidy 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 Avhite 

 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 regu- 

 larly as in Gigas. In that species the general course of the outline is parallel 

 to the hind margin ; in Californica 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 in the form of a single prominent curve, followed by a deep sinus 

 and a wavy line beyond to inner margin. Fi'om the interior outline of the band 

 on Gigas 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
