margin, is a prominent white dot, repeated in next lower interspace, but 

 smaller. Above the anal area which bears the silvery white scales, and in- 

 ward toward base, the ground color is transversely crossed by a more or less 

 prominent series of silvery white wavy lines, interspacial. Midway between 

 base and apex on costa is a prominent dash of silvery white, repeated directly 

 below in the next subcostal interspace, and half way from this to base is an- 

 other dash of silvery white. The discoidal space at its outer portion has two 

 patches of silvery white scales, the balance of the space being of the ground 

 color, with a suggestion of silvery white, transverse, wavy lines. The inter- 

 spaces, one-quarter inch within hind margin, bear a white speck, wanting in 

 some specimens, but fairly prominent in others. 



The general marking of under side varies greatly in the eight specimens in 

 my collection. The prominent and most regular markings are the silvery 

 white space near apex of fore wing, the rust color of discoidal space (which 

 in some specimens suffuses very generously into adjoining interspaces), the 

 subcostal silvery white dashes on hind wing, and the silvery white anal area 

 with the interspacial white dots. 



Taken near Cusilluni in May, 1899, and although one or two 

 specimens have been found in European collections, I believe no 

 description has ever been published.

Habitat: Bolivia, near Coroico. Expanse: i.oo inch. 



Head and eyes black. Antennas black, with white annulations at the base 

 of each joint. Club black, with orange tip. Thorax, above, covered with 

 blue-gray hairs; below, grayish brown. Abdomen blackish above, grayish 

 brown beneath. Legs black, with white annulations at ends and centre of 

 each joint. 



General color of wings, above, nearly black. 



The upper side of fore wing is entirely black, including costa, except a bril- 

 liant dash of lustrous blue within a line drawn from base through centre of 

 discoidal space, then turning downward to inner margin. The blue occu- 

 pies about one-third of wing area. 



The lower wing is black, with the brilliant blue space of fore wing 

 repeated, but covering only the basal quarter of the wing and not en- 

 croaching on inner marginal space. Extending from the end of lower median
