oblong obovntc, tlie ImuT cml hltiiillv polntod. nearly three times ns lonji a.s broad, 

 bhu'klsh itrny. od^eil narrowly iiml lno<in>|iUMiiiusly with black. Siilx-oslal ncrvnle on 

 either side of the cross vein elosln;; the cell curved n little downward. tlii)ii;;h not so 

 nun-li as In the other species of the sienns; upper cross vein dosing tlie cell nearly 

 transverse, ami in continuation of the lower. Fore wiiig.s scarcely so broad as in the 

 other species ; outer niaririu of the hind wluij.s rejiularly curved, its longer tail scarcely 

 loMjrer tlian the breadth of an interspace, the shorter very slight. 



Beneath uniform luslrous, rather dark pearl gray, with n faint lavender reflection — 

 paler gray and without the lavender rellection iu old specimens. E.\treniity of the 

 Cell of tlie/nrc irinijs marked by a transverse, stralglil, narrow black streak, usually 

 longest aliove, entirely and narrowly encircled witli wldte; midway bet ween tliis and 

 tile outer border ami sul>parallel to tlie latter is a series of eiglit small ronndisli black 

 spots enclrcleil witli white, one iu each interspace above the lowest: the upper four 

 are placed in a sliglit curve, tlie arc of a circle whose centre is at the base of the wing ; 

 the fourtli to tlie eighth form a nearly straight series, parallel to the outer border, the 

 llfth a little wltliin the line : the lifth and sixth are tlie largest, the llrst smallest and the 

 rest nearly equal, about one-fourth the size of the eye; the seventh and the eighth are 

 approximated, their white edging confluent. Beyond this band is a submarginal .scries 

 of not very prominent orange lunules. often obsolete, excepting in the median inter- 

 spaces, surmounted l)y lilackishaud tiiese by wiiite scales, the whole parallel to the outer 

 border. The sjiace lietween this and tlie border is often more or less iiifnscated and 

 the outer margin is narrowly edged with t)hick, surmounted in the median and sub- 

 median areas by a slender white line, sometimes continued as a pale inconspicuous 

 line along the whole outer margin. Extremity of the discoidal cell of the laud icings 

 bordered as in the fore wings, but, necessarily, with a longer streak; there is also a 

 somewhat simitar series of roundish spots and streaks, encircled with white ; the upper 

 four are placed iu an arc whoso centre is on the inner border, next the middle of the 

 abdomen ; the llftli and sixtli lie on a line with the flrst. parallel to the discoidal streak ; 

 the seventh consists of a subreniforni spot, toward which the discoidal streak points 

 and tlie direction of w liich it frequently shows ; the last is a long and slender, curving 

 or bent streak, iu the lowest interspace, having a direction nearly at right angles with 

 the general course of the lower portion of the series and extending toward tlie l)ase 

 farther than the tip of tlie abdomen ; the roundish spots of this series arc nearly equal in 

 size, the llrst a very little the largest; usually they are very little larger than the spots 

 of the fore wings. There is a submarginal series of orange lunules varying greatly iu 

 size, conlluent on the lower half of the wing, each surmounted by a black line, almost 

 sagittate, edged with white, and followed by dusky spots, giving place in the lower 

 median and lowest interspaces to small, blackish, triangular spots and, in the medio- 

 submedian interspace, to a very large dusky spot, profusely sprinkled witii caerulean, 

 which almost divides the otherwise eutirely conlluent orange spots; outer border 

 delicately edged with black, surmounted by a slender line of white scales; fringe and 

 tails much as above. 



Abdomen above like the upper surface of the wings, the tip and sides grayish, 

 beueatli white, edged with grayish; alations of upper organ of male (34: IG) well 

 rounded, but slightly angled at the upper distal edge, the lower edge produced to 

 a triangular lobe, overlapping the clasps; the latter straight and nearly equal beyond 

 the slightly gibbous base, with which the apical portion is bent at a slight angle.
