Described from one male, taken near Troy, Jamaica, May 
23, by A. E. Wight. Type in the Cambridge Museum.

Say and pilicornis Aldrich, but differs from both in having 
the wings without cross-bands and the fore and middle tibiae 
pale yellow, it also differs in other characters. It is very 
nearly like salti new species, but differs in the form of the 
fore tarsi.
