 terior lateral angles of median segment produced, acute at apex ; 

 wings ample ; fore wing with costal, medial, the 1st discoidal and 

 radial cells complete, the 1st submedial cell open towards the apex, 

 the 2nd submedial incomplete, the rest not formed : legs slender ;

Genus HETEROCOELIA. 



Heteroccelia, Dalhh. Hym. Eur. ii (1854), p. 21. 



Type, H. nigriventris, Dahlb., from Algeria. 



Range. Known so far only from Algeria. 



5 . Head flat, the vertex not broad ; eyes very =mall, rounded ; 

 antennsTD of moderate length, placed on little raised, rounded, projec- 

 tions ; clypeus strongly vertically carinate. Thorax : the proiiotum 

 anteriorly forming a collar, longitudinally sulcate on the disc. 

 Mesonotum vvith lateral areas simple ; no postscutellum : fore 

 Aving with only the costal and medial cell complete, the radial cell 

 incomplete, the remaining cells obsolete. Abdomen normally 

 formed, narrowing to the apex posteriorly ; in $ with 6 visible 

 segments, the apical segment attenuate ; in J (cqmd Dahlb.) with 5 

 visible segments, the apical segment triemarginate or quadridentate 

 along posterior margin. 



Subfamily ELLAMPINtE. 



Insects of small size, the majority smaller than the majority of 

 the species of the Chnjsidince ; stoutly built. Head more or less 

 transverse and short ; facial cavity generally present ; antennae 

 13-jointed in both 5 and (3 . Thorax short and broad, the pro- 

 notum longer proportionately than in the Chrysidimr ■. \Aings 

 ample, fore wing with the basal nervure more or less arched 

 inwards ; stigmata placed above the produced posterior lateral 

 angles of the median segment close to the bases of the hind wings ; 

 claws of the tarsi dentate ; abdomen broad, very convex above, tlie 

 apical margin incised, subtruncate, sinuate or entire, or only feebly 

 angular, subdentate laterally, never strongly dentate. 



The species are parasitic on the Fossorcs and on the Apida\ 



Kcij to the Genera. 



A. Claws of tarsi multidentate.
