 tie' abdomen equally wide and rounded at tip in the ?; lengthened

I at first named tl is genus Erinnys in commemoration of a discussion 

 "I"" ""■ antenna of Mnxaris which for a Ion- time occupied the Entomo- 

 I Society of France (see loc. cit.) ; hut finding this name already 

 employed, I changed it to Trimeria, which seems scarcely better, as there 

 ; " v a,ir eady two genei . Nevertheless I think it better'to retain 



the new name, Bince it is not identical with the last.
