EULOPHOPTERYX Ashmead, gen. nov. 



This genus comes nearest to Lophocomus Haliday, agreeing with it in all charac- 

 ters except the antennse. The antennse are ten-jointed, as in Lophocomus, but the 

 joints of the funicle are longer than thick, cylindrical, loosely joined, not pedicellate 

 nor compressed, with the club black or brown black, not white. In Lophocomus the 

 funicle joints are distinctly although briefly pedicellate, compressed, two or three 

 wider than long, while the club is white or yellowish-white.
