364 M. W. R. de V. GRAHAM 



63 (62) Gaster (Text-fig. 344) having two bristles of each pygostyle about twice as 



long as the others. Pronotal collar sharply margined anteriorly. Pro- 

 podeum with a moderate-sized reticulate nucha. Gaster not pale-marked. 

 Anterior margin of clypeus weakly emarginate. Fore wing immaculate 



CALLIPRYMNA Graham (p. 467) 

 In most species the pygostylar bristles are subequal in length and relatively 

 short ; but if one or two are somewhat longer than the others, then the 

 pronotal collar is rounded off anteriorly and the propodeal nucha is 

 represented merely by a narrow weakly sculptured strip ... 64 



64 (63) Antennae inserted very high, their toruli at least slightly nearer to the median 



ocellus than to the anterior margin of the clypeus ; scape usually reaching 

 above level of vertex. Propodeal nucha represented merely by a lunate, 

 smooth or transversely-aciculate strip ....... 65 



Antennae inserted at a lower level, their toruli either midway between the 

 median ocellus and the anterior margin of the clypeus, or nearer to the 

 latter ............ 67 



65 (64) Small (1-2 to i-6 mm.) species with thorax only about 1-5 times as long as 



broad, mesoscutum nearly twice as broad as long, pronotum appearing 

 very short in dorsal view ; head and thorax bronze- or bluish black ; anten- 

 nal toruli distinctly nearer to the median ocellus than to the anterior mar- 

 gin of the clypeus, the latter with or without a median tooth 



APSILOCERA Boucek (p. 696) 

 Larger species with thorax 1 -8 to 2 times as long as broad, mesoscutum much 

 less transverse, pronotum appearing longer in dorsal view; thorax, and 

 usually head, bright green to blue ; antennal toruli only slightly nearer 

 to the median ocellus than to the anterior margin of the clypeus . . 66 



66 (65) Anterior margin of clypeus with a median tooth or tubercle, sometimes also 



(Text-fig. 468) with an angular protection on either side of it 



STENOMALINA Ghesquiere (p. 600) 

 Anterior margin of clypeus without a median tooth or tubercle 



CHLOROCYTUS Graham (p. 611) 



67 (64) Anterior margin of clypeus with a median tooth or tubercle, sometimes also 



(Text-fig. 468) with an angular protection on either side of it ... 68 



Anterior margin of clypeus without a median tooth or tubercle ; truncate, 



emarginate, or bidentate ........ 69 



68 (67) Propodeum with nucha represented only by a narrow, transversely-aciculate 



or smooth strip which is sharply-defined in front ; genae not projecting 

 below level of anterior margin of clypeus, the latter nearly always with an 

 angular projection (Text-fig. 468) on either side of the median tooth 



STENOMALINA Ghesquiere (p. 600) 

 Propodeum with nucha large, occupying about half the length of the 

 propodeum, strongly reticulate, not sharply-defined in front ; genae 

 projecting at least slightly below level of anterior margin of clypeus, the 

 latter with a median tooth only (some Rohatina) ..... 69 



69 (68) Antennae inserted very low down ; the lower edge of their toruli at or 



slightly below the level of the ventral edge of the eyes .... 70 



— Antennae inserted higher ; the lower edge of their toruli at least a little 



above the level of the ventral edge of the eyes ..... 73 



70 (69) Postmarginal vein of fore wing only very slightly (up to 1-2 times) as long 



as the stigmal vein .......... 71 



— Postmarginal vein of fore wing more than 1-2 times as long as the stigmal 



vein. ............ 72
