Size moderate, smaller than X. rohi/iise, Peck sp. Dark grey. Pri- 

 maries covered with a fine net-work of blackish lines, strongly marked 

 on costa and diflFused pretty evenly over the entire upper surface of 

 the wings, leaving, nevertheless, a clear costal space before the apex at 

 about apical third. In the male the secondaries are entirely black, 

 except along costal margin, smaller than in the female; external mar-

 primaries in ornamentation and coloration, external margin slightly 

 rounded. Antennae blackish. Thoracic parts covered with mixed

The Tribe Hepiali.ni — curiously resembling the Diurnal Chionobas,

 with the representation of the Family elsewhere, and adds, on the whole, 

 but little distinctive value to the Cuban fauna. So far as I am aware,
