Notauli incomplete or, if complete, very superficial posteriorly ; gaster at 

 least partly smooth ; marginal vein of fore wing not more than twice as 

 long as the stigmal vein ; propodeum with a nucha marked off by a con- 

 striction, plicae and costula more or less indicated 



LARIOPHAGUS Crawford (p. 823) 



170 (168) Ovipositor sheaths far exserted, the exserted portion at least half as long as 



the hind tibia . . . . . . . . . . .171 



- Ovipositor sheaths at most slightly exserted . . . . . .172 



171 (170) Face below level of antennal toruli and clypeus, with several very distinct 



piliferous punctures. Antennae inserted at least slightly above level of 

 ventral edge of eyes .... ROPTROCERUS Ratzeburg (p. 423) 

 Face and clypeus without piliferous punctures. Antennae inserted at or 



slightly below level of ventral edge of eyes . . . . . .190 



172 (170) Antennal clava either acute apically (Text-fig. 300) ; or with a terminal 



spur (Text-fig. 299 ; often indistinctly segmented or solid . . .173 



Antennal clava neither acute nor with a terminal spur, distinctly three- 

 segmented . . . . . . . . . . 175 



173 (172) Gaster ovate to lanceolate, distinctly pointed apically ; postmarginal vein 



distinctly longer than the stigmal vein. Gaster often more or less 

 extensively red or yellow . . . . . . . . .174 



- Gaster subcircular, obtuse apically, disregarding the ovipositor sheaths, if 



visible ; postmarginal vein usually not or hardly longer than the stigmal 



vein. Gaster not pale-marked . . . . . . . .175 



r 74 ( x 73) Propodeum as long as or longer than the scutellum, strongly reticulate, its 

 nucha large and strongly produced backwards so that (in dorsal view) its 

 hinder edge is nearly or quite level with the tips of the hind coxae. Gaster 

 usually reddish-marked ; all coxae mainly to entirely reddish. Underside 

 of fore wing with a row of rather long, downward-pointing hairs a little 

 below the marginal vein .... CALLITULA Spinola (p. 458) 



- Propodeum shorter than the scutellum, its nucha short or indistinct, more 



weakly reticulate, and produced at most slightly beyond the bases of the 

 hind coxae. Pale areas of gaster (when present) more yellowish ; coxae 

 often dark, occasionally all pale. Underside of fore wing, below marginal 

 vein, with only fine, short scattered hairs . HOMOPORUS Thomson (p. 444) 

 T 75 ( x 73) Gaster subcircular, obtuse apically, disregarding the ovipositor sheaths, if 

 visible ; postmarginal vein of fore wing usually about equal in length to, or 

 hardly longer than, the stigmal vein . . . . . . .176 



- Gaster ovate to lanceolate, usually distinctly pointed apically but if obtuse 



then obviously longer than broad ; postmarginal vein usually distinctly 

 longer than the stigmal vein, rarely only slightly so . . .177 



I 7& ( x 75) Occiput margined. Antennae clavate ; clava subobtuse, ventrally with a 

 large area of micropilosity which extends nearly to its base. Eyes with 

 rather long conspicuous hairs. Fore wing with basal cell extensively pilose, 

 speculum small and not reaching down to cubital vein, apical margin of 

 wing ciliate DIGLOCHIS Forster (p. 782) 



- Occiput not margined. Antennae subfusiform ; clava pointed, ventrally 



with only a small area of micropilosity on its third segment. Eyes with very 

 short inconspicuous pubescence. Fore wing with basal cell bare or pilose in 

 distal part only, speculum large and extending to cubital vein 



CYCLOGASTRELLA Bukovkij (p. 796) 

 J 77 ( x 75) Pronotal collar usually (Text-fig. 317) as wide as the mesoscutum, if slightly 

 less wide, then the hairs of the head and thorax are conspicuous and, at 

 least most of them, whitish. Pronotum, in front of the collar, descending
