368 M. W. R. de V. GRAHAM 



82 (81) Head thick, in dorsal view (Text-fig. 304) less than twice as broad as its 



maximum length ; marginal vein of fore wing 2-3 to 2-6 times as long as 

 the stigmal vein ; propodeum with a moderately large, reticulate nucha ; 

 flagellum short, all funicular segments transverse GBELCIA BouCek (p. 699) 

 If the head is comparably thick and also the marginal vein is more than 

 twice as long as the stigmal vein, then the propodeal nucha is represented 

 merely by a narrow transversely-aciculate strip ..... 83 



83 (82) Gaster, not counting the ovipositor sheaths, if visible, subcircular or with its 



apex obtuse, and with the last tergite shorter than its basal breadth, some- 

 times so short as to be hardly visible, in one genus turned downwards, so 

 as to be visible only from behind ; ovipositor sheaths hardly or only just 

 reaching tip of last tergite and so invisible in dorsal view .... 84 



- Gaster ovate to lanceolate, distinctly pointed apically, sometimes acuminate ; 



tips of ovipositor sheaths normally projecting at least very slightly beyond 



tip of last tergite and so visible in dorsal view ...... 90 



84 (83) Mesopleuron wholly reticulate ; gena with a small hollow above base of 



mandible ; head in front view (Text-fig. 457) narrowing strongly towards the 

 mouth, mandibles large and falcate ; all funicular segments transverse 



KALEVA Graham (p. 596) 

 Mesopleuron most often with a mainly to entirely smooth subtriangular area 

 below the base of the hind wing ; if this area is at all extensively reticulate, 

 then the gena lacks a hollow, the head is not narrowed towards the mouth, 

 the mandibles are smaller, and the funicular segments are not transverse 85 



85 (84) Gena with a small hollow above base of mandible ; flagellum (Text-fig. 354) 



cylindrical, all funicular segments except sometimes the sixth longer than 

 broad, each of these segments with at least two rows of sensilla, often with 



three CAPELLIA Delucchi (p. 475) 



Gena without a hollow. At least funicular segments five and six quadrate 

 to transverse ; flagellum often slightly clavate, funicular segments some- 

 times with only one row of sensilla ....... 86 



86 (85) Head (Text-fig. 305) : oral fossa small, its breadth only about 1 -5 times the 



malar space ; genae converging strongly ; both mandibles with four teeth, 

 the two middle ones approximated ; anterior margin of clypeus slightly 

 curved forward. Propodeum with a small reticulate nucha. Petiole and 

 base of gaster often testaceous. All or most of the funicular segments 

 transverse .... ENDOMYCHOBIUS Ashmead (p. 470) 



- Oral fossa larger, its breadth twice or more than twice the malar space ; genae 



more or less buccate. Left mandible, or both mandibles, with three teeth, 

 none of the teeth approximated. Anterior margin of clypeus emarginate 

 or truncate. Propodeum without a distinct nucha. Petiole and gaster 

 usually dark, rarely a little pale ....... 87 



87 (86) Last tergite of gaster (Text-fig. 306) turned downwards at nearly a right angle 



to the preceding tergite, so as to be nearly vertical ; ovipositor sheaths, 

 visible only from behind, stout. Pronotal collar not margined. Post- 

 marginal vein at least a little shorter than the marginal vein 



TOMICOBIA Ashmead (p. 784) 



- Last tergite of gaster not turned abruptly downwards, but if sloping some- 



what steeply then the pronotal collar is sharply margined ... 88 



88 (87) Postmarginal vein of fore wing distinctly shorter than the marginal vein. 



Pronotal collar sharply margined except just at the sides. Usually both 

 mandibles have three teeth, occasionally the right mandible has four, or 

 both have four DIRHICNUS Thomson (p. 787)
