Epyris Extraneus Bridwell (Bethylidae), a Fossorial Wasp 



That Preys on the Larva of the Tenebrionid Beetle, 



Gonocephalum Seriatum (Boisduval) 



BY PKA.NCIS X. WILLIAMS. 



Ejiyiis r.vtraiiefiis was first taken in the Hawaiian Islands 

 by Swezey in October and November, 1915, on the gronnds of 

 the Experiment Station of the Hawaiian Sugar Planters' Asso- 

 ciation at Honolulu, Oahu. Subsequently he found it in 1917 

 on the island of ^Maui. It is now quite abundant on Oahu 

 wlien' it seems more partial to the lowlands and can be taken 

 at all seasons of the year. Bridwell, who described this Epyris, 

 (Xotcs on a Peregrine Bethylid, Proc. Haw. Ent. Soc. for 

 191(;, Vol. Ill, Xo. 4, pp. 270-279, 1917), also identified 

 specimens from Los Banos, i^liilippines, as belonging to this 

 species and so it seems pr' ilia hie that it has a fairly wide 

 Oriental disti-ibution. 



Very little is known about the life-history of the genus

 Haw. Ent. Soc. for 1910, Vol. Ill, Xo. 4, pp. 202-20:), 1917^i 

 found an Epijris sp. luar ( 'apetown. South Africa, draggiui:,' 

 a small tenebrionid larva between its jaws, and in the same
