 Habitat: Suapure, Venezuela. Expanse: i.io inches. 



Head and palpi above black, below tawny. Thorax above black, below black 

 with gray hairs. Abdomen above black, below brown with a white dash at 

 thorax junction. Antennae black. Club black above, below tawny. Legs 

 black near body, turning to tawny toward tips. 



Upper side of fore wing black. Near apex, in subcostal area, is a small 

 white dot. Below this, skipping one interspace, is a series of five interspacial 

 white spots running downwards towards centre of inner margin, the first two 

 small, the third very large, the fourth small, and fifth a small dot in lowest 

 submedian interspace. 



Upper side of hind wing black. A broad and very prominent white band 

 runs from centre of inner margin towards upper angle, extending across one- 

 half the wing only, stopping near end of discoidal space. Inner margin slightly 

 dusted with gray scales. 



Marginal fringes of ground color, turning to white at anal angle. 



Under side of fore wing the same as upper surface except that the spots are 

 more closely connected and the ground color is brownish. 



Under side of hind wing the same as upper surface except that the prominent 

 band extends completely across the wing from a point near the upper angle, on 

 costa to centre of inner margin and of unvarying width. This band is creamy 

 white. 



Variations. — My small series of specimens shows no variation ex- 

 cept that the two small subcostal spots are sometimes wanting, and 

 the lowest dot, also, on fore wing. 



This species was not found in collections here, nor in the Godman 

 collection, British Museum, etc.
