sometimes incomplete but meeting on the disc of the mesoscutum. Gaster 

 (Text-fig. 39) usually attached to the propodeum at a relatively high level, 

 the lower edge of the petiolar foramen being usually level with the upper 

 surface of the hind coxae as seen in profile ; one or more of the bristles of 

 each pygostyle very long. Antennae 1 1- to 13-segmented, with one anellus ; 

 in female with seven funicular segments and a solid or three-segmented 

 clava ; in male with nine funicular segments and a short clava which is 

 solid or imperfectly two-segmented. Body of Dipara $ 6" Text-figs. 39, 52 



DIPARINAE (p. 63) 

 Vertex clothed with hairs or bristles which are relatively uniform in length 

 and most often finer and shorter than in the above ; scutellum usually with 

 more than four bristles, if with only four then the scutellum is not longi- 

 tudinally strigose. Notauli complete, not meeting posteriorly. Gaster 

 usually attached to propodeum at a lower level, with the petiolar foramen 

 situated between the hind coxae ........ 7 



7 (6) Macropterous ; front edge of costal cell of fore wing (Text-fig. 37) strongly 



curved apically, so that the wing appears excised at the point where the 

 submarginal vein meets the marginal vein (Epicopterus and some exotic 



genera) EUNOTINAE (part) (p. 67) 



Either the front edge of costal cell of fore wing in its apical portion is straight 



or at most weakly sinuate ; or the species is brachypterous ... 8 



8 (7) Species with the following combination of characters : head (Text-fig. 38) with 



posterior ocelli touching the occipital edge, which is sharp ; head in front 

 view subtriangular ; genae long to very long ; scutellum large, slightly 

 to considerably longer than the mesoscutum, sometimes more or less 

 overlapping the gaster ; fore wing with postmarginal vein usually at most 

 as long as, rarely slightly longer than, the stigmal vein ; first tergite of 

 gaster very large, usually concealing the remaining tergites though some- 

 times (Scutellista) occupying only about half the gaster, in which case the 

 scutellum partly overlaps the gaster ; propodeal callus with a raised longi- 

 tudinal crest which ends posteriorly in a tooth ; antennae eight- to ten- 

 segmented, inserted at least slightly below the level of the ventral edge of 

 the eyes. Body of Eunotus $, Text-fig. 54 . EUNOTINAE (part) (p. 67) 



If the occipito-vertical edge is sharp, then the posterior ocelli do not touch it 

 (except sometimes in Pirene, in which the head is not subtriangular, the 

 genae are short, the scutellum is smaller, and the other characters do not 

 all agree with the above). Head in front view more often more or less 

 oval ; scutellum rarely distinctly longer than the mesoscutum, not over- 

 lapping the gaster [except partly in some exotic Cleonyminae] ; fore wing 

 with postmarginal vein often longer than the stigmal ; first tergite of 

 gaster rarely occupying more than half the total length ; propodeal callus 

 rarely with a longitudinal ridge ; antennal formula often otherwise . . 9 



9 (8) Wings bitten off somewhere near their bases, so that the venation, except part 



of the submarginal vein, is missing (dealate specimens of Bairamlia) 



ASAPHINAE (part) (p. 77) 

 - Wings fully developed with complete venation . . . . . . 10 



10 (9) Fore wing with marginal vein conspicuously thickened, either throughout, or 



in its proximal half (cf. Text-figs. 285, 286, 291, 323, 324) . . . 11 



Fore wing with marginal vein not conspicuously thickened. Note : the para- 

 stigma, which may be thickened, is not counted as part of the marginal vein 13 



11 (10) Clypeus with at most a trace of strigose sculpture at the sides, its anterior 



margin subtruncate ; hind tibia with one spur ; antennal formula 11 263 

 (male Epicopterus only) (Text-figs. 72-74) . . EUNOTINAE (part) (p. 67)
