CHIONOBAS I. 



pale o-ray-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 surfoce covered 

 by fine, abbreviated, brown streaks, least densely on costal margin, most next 

 base and over sub-median intei'space, and for a broad space along hind margin ; 

 a white point next the margin on the middle of each interspace ; the ocellus, 

 when 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 

 from margin to margin by a Ijroad, irregular band, narrowly edged on either 

 side by a blackish-brown border ; the sj^ace 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 I'eaches 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 oftset, 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; legs 

 black, the tibiie gray-brown ; palpi black with gray hairs interspersed ; antennse 

 brown, beneath gray ; club dull ferruginous, gray beneath. 



Female. — Expands 2.6 inches. 



Upper side paler than in the male, fixding 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 accom])anied by a small 

 blind ocellus on the interspaces next preceding ; secondaries mai'ked as in the 

 male. Under side of both wings paler than in the male ; the outlines of the band 

 similar. 



The individuals represented on the Plate were sent me by Mr. James Behrens.
