<3 5 , Brazil (Becker). Type, B.M. 



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.
