- Marginal vein at most 1 -4 times as long as the stigmal vein 



SPINTHERUS Thomson (p. 480) 



118 (114) Lower edge of antennal toruli hardly above level of ventral edge of eyes . 119 



Lower edge of antennal toruli distinctly above level of ventral edge of eyes 121 



119 (118) POL hardly greater than OOL. Postmarginal vein of fore wing about as 



long as the marginal vein. Pedicellus in dorsal view somewhat less than 

 twice as long as broad. 



Body green to blue . . CHLOROCYTUS Graham (p. 611) 



POL much greater than OOL. Postmarginal vein shorter than the marginal 



vein. Pedicellus in dorsal view fully twice as long as broad . . .120 



120 (119) Antennal flagellum clavate ; antennae mainly to wholly yellow. Body 



bright green to blue ; legs, except coxae, mainly to wholly yellow ; gaster 

 usually with a yellowish spot or band . MESOPOLOBUS Westwood (p. 638) 

 Antennal flagellum filiform, black. Body bronze or olive-bronze ; legs 

 testaceous or partly infuscate ; gaster immaculate 



TOMICOBIA Ashmead (p. 784) 



121 (118) Antennae with first funicular segment at least slightly shorter than the 



pedicellus ........... 122 



- Antennae with first funicular segment as long as or longer than the pedicellus 123 



122 (121) Either the clypeus is mainly reticulate ; or the metanotal dorsellum is 



reticulate. Both mandibles with three teeth. Scutellar frenum distinctly 



marked off TOMICOBIA Ashmead (p. 784) 



Clypeus strigose ; metanotal dorsellum smooth or nearly so. Left mandible 

 with three teeth, right mandible with four. Scutellar frenum not distinctly 

 marked off except at the sides . . HABROCYTUS Thomson (p. 494) 



123 (121) In a dorsal view of the thorax, the pronotal neck (Text-fig. 333 n) appears at 



least slightly longer than the collar, the latter short medially. Post- 

 spiracular sclerite (Text-fig. 335) broader, relatively uniformly reticulate. 

 Marginal vein of fore wing 1 -65 to 1 -85 times as long as the stigmal vein 



CHLOROCYTUS Graham (p. 611) 

 In a dorsal view, the pronotal neck is usually invisible (cf. Text-fig. 405) or 

 appears shorter than the collar, occasionally as long as the collar, the latter 

 often long medially. Postspiracular sclerite (Text-fig. 336) narrower, 

 more weakly and irregularly sculptured. Marginal vein 1-35 to 1-7, but 

 usually not more than 1 -5, times as long as the stigmal vein 



HABROCYTUS Thomson (p. 494) 

 and PTEROMALUS Swederus (p. 488) 



124 (in) Clypeus (Text-fig. 307) with strong striae which extend some way up the face 



and genae ; pronotal collar long, medially about one fifth as long as the 

 mesoscutum or slightly more ; marginal vein of fore wing nearly twice as 

 long as the stigmal vein ..... HOBBYA Delucchi (p. 569) 



- Clypeus with finer striae ; pronotal collar often shorter medially ; marginal 



vein sometimes shorter relative to the stigmal vein . . . . .125 



125 (124) Fore wing with distal third to half of basal cell pilose ; thorax distinctly de- 



pressed, scutellum in profile appearing nearly flat ; gaster immaculate 



ANOGMUS Forster (p. 628) 



- Basal cell, not counting basal vein, usually bare, but if somewhat pilose 



distally then the thorax is convex dorsally and the scutellum in profile 

 appears distinctly curved ; sometimes also the gaster has a yellowish spot 

 or band ............ 126 



126 (125) Gena with a small hollow above the base of the mandible ; marginal vein of 



fore wing only 1-2 to 1-3 times as long as the stigmal vein ; all funicular 

 segments longer than broad, the first at least twice as long as the pedicellus ;
