form a straiijlit series extendiiiG; from the middle of tlie outer two-flfths of the costal 

 maririn toward the middle of the outer border; the median spots when both are 

 present arc in a line nearly at rij;ht angles to this, the outer limit of the upper 

 one being in the centre of its interspace. The wing is crossed by three incon- 

 spicuous bauds of clouded blackish spots: the inner and broader extends' from 

 the upper border of the cell, having the vitreous spot at its outer extremity, to the 

 middle of the basal two-thirds of the submedian nervure; its inner border is obscure 

 but its outer passes from above downward in successive equal steps at the nervures, 

 crossing each interspace at right angles, filling the entire base of the upper median in- 

 terspace ; sometimes this belt is reduced to a pair of similar, longitudinally oval, black- 

 ish patches, one above the other, in the cell and a similar pair in the medio-submedian 

 interspace; the middle curving band extends from the costal margin to the sub- 

 median nervure and lies midway between the inner band and the outer border includ- 

 ing, next its inner border, all the vitreous spots ; the spots of which it is composed 

 are slightly more distinct than those of the inner band though sometimes scarcely dis- 

 tinguishable and, above the lower median nervule, are generally elongate triangular, 

 twice as long as broad, the apex outward, but above, next the vitreous spots, they 

 degenerate into uniform dashes and below the median become irregularly quadrate ; 

 the wing is frequently flecked with short longitudinal white hairs or, toward the apex 

 of the wing, hoary scales, which are more abundant than elsewhere upon the borders of 

 the two bands just described, tending often to accentuate them or to enliven the paler 

 parts with a grayish tinge; the outer band consists of a submarginal regular series of 

 very nearly equal spots similar to the others but roundish and scarcely half so broad as the 

 interspaces, often accompanied externally by a slight and limited pale flecking ; usually 

 the outer margin of the spots is more distinct without this aid, especially in such as 

 have the spots of a roundish, sagittate form, the apex outward; outer margin narrowly 

 edged with blackish ; fringe uniform dark brown, generally slightly paler than the 

 general ground color of the wing. Hind wings of a nearly uniform tint, not quite so 

 dark as the darkest parts of the fore wings, a little before the hind margin enlivened 

 by paler, yellowish brown, roundish spots, almost never at all defined and usually giving 

 only the efl'ect of a paler, indistinct, clouded, interrupted band in the middle of the outer 

 two-fifths of the wing and parallel to the outer margin ; outer margin edged narrowly 

 with blackish ; fringe as in the fore wings, but paler in the outer half, occasionally 

 very minutely white-tipped. 



Beneath dark purplish brown, on the hind wings uniform, on the fore wings paling 

 toward the inner margin, where it becomes pale slate brown. Fore wings with the 

 vitreous spots larger and more distinct than above, the obsolete ones often present 

 and the whole edged obscurely with dusky, so as often to give the semblance of an ex- 

 tra-mesial dusky band ; beyond this the wing is a very little lighter, rendering more 

 distinct the always oliscure repetition of the submarginal spots of the upper surface, 

 which here are larger and are generally followed by faint, lighter fleckings exteriorly ; 

 all these markings are much more distinct in the $ , which has a few scattered, hoary 

 scales near the tip of the wing; outer border narrowly edged with blackish brown ; 

 fringe of the ground color of the wing, but a little paler at the base. JJind goings with 

 the dull, obscure markings of the upper surface repeated with the same vagueness and 

 faintness, excepting in the ? , where the dark spots are not in themselves more 

 distinct, but they are touched on either side by minute spots of dirty white, exteriorly 

 often in the form of short, longitudinal streaks leading to the border; margin and 

 fringe as in fore wings. 



Abdomen very dark browu, tinged above with purplish, below grayish brown. 

 Upper organ of male appendages (36 : 13-16) having the centrum long and slender, not 

 high. Posterior extremity bearing greatly elevated asymmetrical alations, united in a 

 somewhat horseshoe-shaped or semi-infundibuliform, curving, hollowed plate or crest, 

 excessively produced as a slightly upraised, pointed triangle on the right side, directed 

 backward and upward; the whole crest faces upward and backward, its united upper 

 edge fringed with minute spicules, and is supported on either side by a slender ridge
