prongs. The antenna* are 13-jointed, with one ring joint, in both sexes, the scape 

 very short, oval, the pedicel very minute and often more or less hidden within the 

 apex of the scape.

Family LI I. Belytid.^. 



The venation, which is quite distinct from the other families, distinguishes the 

 family. The antenna; are porrect, inserted on a frontal prominence, filiform, setaceous 

 or subclavate, and 14- or 15-jointed, with a long scape ; mandibles usually short, with 

 a tooth within, rarely falcate and decussate ; maxillary palpi 4 or 5-jointed ; labial 

 palpi 3-jointed; legs rather long and slender, the tibial spurs I, 2, 2, the tarsi long 

 and slender, 5-jointed, the claws always simple ; while the abdomen is variable in 

 shape but always distinctly petiolate. 



The family comes quite close to the Diapriidce but is easily separated by having 

 3-jointed labial palpi and by the venation of the hind wings, which have a basal cell. 



The group is supposed to be parasitic upon Dipterous larvae inhabiting fungi. 

 Beiyla ftdva Cameron is recorded from Bolitopliila luininosa.
