DESCRIPTION OF A NEW SPECIES OF DIRCENNA 

 FROM PERU. 



By Walter Dannatt, F.E.S. 



.^i 



Dircenna barretiii, sp. n. 

 Male. Anterior wings transparent golden, with margins very dark 

 brown (almost black), wider at apex. A broad dark band at end of 

 cell, which is continued in a lesser degree down the second median 

 nervule to the margin. Posterior wings have wide irregular margins 

 with a submargiual series of five irregular white spots. Under side as 

 above, but apex of anterior wing has three elongated white spots. 

 Expanse, 3^% in. 



Hab. Perene, Peru. 



This remarkable species, though believed by Dr. Staudinger 

 to be a Dircenna, differs in some respects from hitherto known 

 species in this genus (see fig.). 



I have great pleasure in naming this insect after an American 

 friend, Mr. Otis W. Barrett, to whom I am indebted for the 

 addition of many beautiful specimens to my collection.
