MYLOTHRIS, new species or variety. (?) 



There is a female specimen of a Mi/Jofhri.s very clo.sely allied to 

 ]\I. bcrenice, Ilewitson, bnt tlift'cring- in having the apical portions of 

 the i)rimaries much less broadly marked with black, and the si^ots 

 at the ends of the nervules in the secondaries also much smaller in 

 size, in fact reduced to niere points. The snrface of the wing is also 

 not nearlj^ as dusky as in specimens of Berenice (females) from the 

 West Coast. As the specimen is unique and in rather poor case, I do 

 not feel justified in describing it as a new species, though I am inclined 

 to designate it under the varietal name lierenlcUles. It apparently 

 is an eastern local race of the well-known West African insect.

 side is whitish.
