receding. Antennal scape virtually as long as an eye 



CYCLOGASTRELLA Bukovskij (p. 796) 



- Either the antennal toruli are not or hardly nearer to the anterior margin of 



the clypeus than to the median ocellus ; or else the head is not protuberant 

 at level of toruli and the face hardly recedes . . . . .109 



109 (108) Mesepisternum wholly reticulate. POL only about equal to OOL. Fore 

 wing with basal cell with some scattered hairs ; speculum, on lower 

 surface of wing, somewhat effaced by scattered hairs ; marginal vein 

 about twice as long as the stigmal vein. Pronotal collar not margined 



XIPHYDRIOPHAGUS Ferriere (p. 426) 



- Mesepisternum usually with a shiny and mainly to entirely smooth area below 



the base of the hind wing ; if this area is reticulate, then the other 

 characters do not all agree with the above . . . . . .110 



no (109) Oral fossa (cf. Text-fig. 305) small, its breadth at most 1-5 times the malar 

 space. Gaster subcircular or subtriangular, shorter than the thorax ; 

 petiole yellowish. 



Pronotal collar very short medially, usually slightly margined 



ENDOMYCHOBIUS Ashmead (p. 470) 



- Oral fossa larger, its breadth more than 1 -5 times the malar space. Gaster 



most often oblong to sublinear, if subcircular then the petiole is not 

 yellowish . . . . . . . . . . . .111 



in (no) Pronotal collar without trace of a margin, often rounded off in front, though 



sometimes forming an abrupt edge with the pronotal neck . . . 112 



- Pronotal collar margined, at least in the middle ..... 124 



112 (in) Fore wing with distal half or more of basal cell pilose . . . .113 



- Basal cell of fore wing, not counting any hairs on basal vein, bare or with at 



most a very few hairs near the basal vein . . . . . .114 



113 (112) Propodeum short, medially only slightly more than one third as long as 



scutellum ; plicae absent or indicated only posteriorly. All funicular seg- 

 ments, except sometimes the first, at least slightly transverse 



CECIDOSTIBA (ANASTIBA) sgen. n. (p. 565) 



- Either the propodeum is relatively longer, or has plicae distinct throughout, or 



some of the funicular segments in addition to the first are quadrate to 

 longer than broad . . . . . . . . . .114 



114 (113) Propodeum with plicae represented only by foveae at the base of the pro- 



podeum ; spiracular sulci shallow or almost absent . . . .115 



- Propodeal plicae sharp at least posteriorly . . . . . .118 



115 (114) Propodeum between the spiracles very shiny, smooth or weakly alutaceous. 



Fore wing with postmarginal vein somewhat longer than the marginal 



vein ; basal cell with scattered hairs distally LAMPOTERMA Graham (p. 687) 



- Propodeum between the spiracles not very shiny, distinctly, sometimes quite 



strongly, reticulate. Fore wing with postmarginal vein shorter than, or 

 at most as long as, the marginal vein ; basal cell, not counting basal vein, 

 usually bare, rarely with a few hairs distally . . . . .116 



116 (115) Flagellum with numerous short sensilla arranged in two to four rows on each 



segment ; hairs of flagellum subadpressed. Marginal vein of fore wing 



2 to 2-3 times as long as the stigmal vein . . MERISUS Walker (p. 443) 



- Flagellum with sparser sensilla which are arranged in one row on at least the 



distal segments of the funicle ; hairs of flagellum outstanding. Marginal 



vein often shorter relative to the stigmal vein . . . . .117 



117 (116) Marginal vein of fore wing 1-5 to 2-5 times as long as the stigmal vein
