the uiuler surface ami the tip wliite; antennae l)lackisli, annnlatecl at the base of each 

 joint with white, much the broadest on the under inner surface where it often 

 stretches over fully half of the joint ; club above blackish brown, often with a pur- 

 plish tinge, the apical three or four joints dirty white; below dull brownish yellow, 

 ashy toward the base and sometimes along the middle line. Tongue pale dirty luteous. 



Thorax covered above with blackish brown hairs, overlaid profusely with hoary blue 

 hairs {$) or more sparingly with pale brown hairs (?), the shoulder covers w'ith 

 blackisli brown scales edged, especially externally, with pale scales and, in the $ , over- 

 laid l)y bluish hairs ; beneath white with a faint grayish yellow wash ; legs silvery 

 white, scarcely specked with blackish, the base of the tars.al joints heavily marked 

 above with I)lackish brown, least so on the basal joint. Tip of the spurs redilish; 

 spines black, claws bright testaceous. 



Wings above either of a dark lustrous purplish violet, the outer borderof fore wings 

 to the width of an interspace, but generally with its interior limit ill-defined and the 

 costal margin of the hind wings rich dark brown, the nervules, especially in the outer 

 half of both wings, more or less dusky and increasingly so toward the border (J) ; or 

 nearly uniform rich dark lustrous brown, the middle of the wings with an indistinct 

 ruddy hue (?). Fare VHmjs v{\X,\\ the costal edge white, the tip of the cell marked 

 transversely with an obscure brownish dash, indistinct of course in the $. Fringe 

 with the basal half dark brown, more distinctly so along the outer half of the base, 

 mixed with white next the base, the outer half silvery white. Hind wings: the outer 

 margin in the J often has a dark border as in the fore wings, and in both sexes has 

 also in general the following markings, which are sometimes partially or wholly obso- 

 lete : in each of the median interspaces a round black spot, often margined externally 

 with blue, and separated from the outer border by only a narrow black space and 

 surmounted by a large orange lunule ; in the medio-submeiliau interspace a trans\'erse 

 black spot similarly situated, margined exteriorly, and sometimes interiorly, but often 

 faintly, with a line of blue atoms ; black spots similar to those of the median interspaces 

 also often occur in the lower subcostal and subcosto-mediau interspaces, but, if mar- 

 gined at all, only with blue; the tail is black with a white fringe. Fringe white with 

 a pale dusky line before the middle; at the nervure tips dusky on the basal half. 



Beneath nearly uniform pale steel or satin gray, a shade duskier toward the apex of 

 the fore wings and paler next the inner border of hind wings. Fore wings with 

 a slender, transverse, slightly curving, ilark brown streak at the tip of the cell, mar- 

 gined narrowly with white ; midway between this and the outer border is a transverse 

 row of six dark brown spots also encircled narrowly with white, subparallel to the outer 

 border, one in the medio-submedian interspace, and one in each of the tive succeeding 

 interspaces above it ; those in the lower subcostal and subcosto-median interspaces are 

 removed farther outward than the others by their own width ; the upper ones are 

 transversely oval; that in the lower median interspace subcrescentiform, a little diago- 

 nal, the lowest transversely linear ; the outer margin is narrowly dark brown, followed 

 inwardly by an equally narrow but obscure edging of pale or dull white, most distinct 

 in the interspaces ; this again is followed by pretty large, transverse, oval, cloudy spots, 

 and tliese at a slight distance, or at about an interspace's distance from the margin, Ijy a 

 similar series of darker curved bars, opening outwards, more distinct aud broader 

 below. Fringe white with a dusky line through the middle. I{ind wings with a small 

 round black spot encircled with pale in the middle of the costo-subcostal interspace, 

 just beyond the first divarication of the subcostal, and another in the middle of the 

 lower half of the cell, just beyond the first divarication of the median; the outer limit 

 of the cell is marked by a line of pale brown scales, edged with pale, and there is an 

 irregular extra-mesial row of roundish or transverse oval, blackish or blackish brown 

 spots encircled with whitish; one is found in the costo-subcostal interspace midway 

 between the spot formerly mentioned and the outer border of the middle of the inter- 

 space ; a second just lielow it in the succeeding interspace; the next two are nearer 

 the margin, one below the other in the lower subcostal and subcosto-median inter- 

 spaces, being more than midway from the tip of the cell to the outer border ; one in the
