Family PTEROMALID^ Walker. 



Subfamily FTEROMiALIN'JE .A-shnnead. 

 Tribe PTEROIMALINI Ashmead. 



Genus HYPOPTEROMALUS Ashmead. 



Since the type species of this genus has a well-developed neck to 

 the metathorax and a short but plainly visible petiole, it does not well 

 fit in the place in Doctor Ashmead's tables in which he has put it. 

 The following table based on antennal characters and the color of the 

 logs separates both sexes:
