There are five males which agree perfectly with the description given 

 by Standmger, which is rather better than his figure, which is not 

 characteristic so far as the fine black lines on the disk of the primaries 

 are concerned. In the figure it is not indicated that the white gronnd 

 is marked by snch lines, and the drawing simply indic-ates the nenra- 

 tion In natnre the nenration is not visible withont the use ot artificial 

 means of determining it, except as it is indicated upon the disk by tlie 

 fine deep black lines upon the median, the radial, and the lower costal 

 nervules from the middle of the wings to the outer margin. 



In addition to the five males, there are three females which I think 

 are undoubtedly referable to this species. The female apparently was 

 unknown to Staudinger, and I accordingly append the following 



description: w ^ vi -^ T'n.i 



Female.-Boay much as in the male, attenn.e and teet likewise. The 

 winosonthe upper side are pure white, somewhat broadly powdered 

 with bhnkisli scales at their base. The primaries have a smal oblong 

 ocelliform spot at the end of the cell, followed by a curved band of four 

 to seven macuhe running from the costa toward the inner margin across 

 the disk parallel to the outer margin. The spots do not extend beyond 

 vein 1 in the direction of the inner margin in any specimen before me, 

 and in two cases do not pass beyond vein 2. The apex is niarked with 

 duk blackish gray clouding gradually diminishing in width from the 

 costa toward the outer angle, which is not reached by these darker 

 markings. This dark area is interrupted by a series of subtriangular, 

 pale, creamv, white spots on the interspaces-exactly on tlie 'uargin. 

 The extremity of each nervule is marked by a minute black do . On 

 the under side the markings of the upper side of the primaries faint y 

 reappear, and m addition ti.e apical area is faintly powdered with
