Mr. Walker's description is a compound one; it begins with the male, which I there- 
fore consider the type. The description of the secondaries, “ Hind wings whitish, 
tinged with brown and with several darker brown bands,” is evidently taken from the 
example from Rio Janeiro, supposed by Walker to be a female variety, but clearly a 
distinct species; the secondaries of D. lichenea are very similar to those of D. florestan, 
excepting that the central whitish bands in the male are more distinct.
