Maro-inal vein rarely more than twice as long as thick, head with rather sparse, 



scattered, umhilicate punctures, the scutellum a little 

 longer than the mesonotum. 



Head not wider than the thorax between the wings; flagellum not short, 

 filiform, and clothed with rather short sparse hairs, the 

 funicle joints longer than wide, the first a little the 

 longest , . (46) Hemencyrtus Ashmead, new genus. 



Head wider than the thorax between the wings ; flagellum short, strongly 

 clavate, as in the female; the club large and longer than 

 the funicle, the joints of the latter minute annular. 



(47) Coccoplioctonus Ashmead, new genus. 



38. Mesonotum as long as the scutellum or nearly, rarely somewhat shorter, the 



surface finely shagreened, at most with some feebly 

 defined sparse punctures ; marginal vein shorter than the 

 stigma], the latter not very short; flagellum filiform, 

 pilose, the funicle joints about twice as long as thick; 



eyes bare (48) Phamodiscus Forster. 



Mesonotum much shorter than the scutellum, finely delicately shagreened or 

 rugulose especially anteriorly; marginal vein a little 

 longer than the stigmal; flagellum subclavate, densely 

 pubescent, the funicle joints 2-6 not longer than thick, 

 if anything a little wider than long ; eyes pubescent. 



(49) Bhytidothorax Ashmead, new genus. 



39. AntenuiB inserted near the mouth border or far below the middle of the 



face - 40 



Antennai inserted on or a little above the middle of the face. 



Frons subconves, somewhat coarsely and closely punctate; thorax rather 

 coarsely shagreened or finely regulose ; scape not extend- 

 ing beyond ocelli; front wings with the marginal, post- 

 marginal and stigmal veins long, subequal. 



(50) Tanaoneura Howard. 

 Frons highly convex, smooth and polished, as is also the thorax ; scape long, 



extending far beyond the ocelli; front wings with the 

 marginal, postmarginal, and stigmal veins rather short, 

 the marginal thickened with a fuscous cloud or band 

 beneath; flagellum with 6 long branches.

40. Antennte with the funicle 2, 3, 4, or o-jointed 57 



AntenuiB with the funicle 6-jointed (in a single case 2-joiuted). 



Metathorax bare, or with the lateral ridges superiorly alone pilose 44 



Metathorax with the pleura and the lateral ridges always clothed with a

41. Antenuie unlike those of the female, filiform, pilose, or with whorls of hairs, or 



the funicle joints dentate or subpedunculate, with whorls 



or fascicles of hairs 42 



AntenufB similar to those of the female, filiform or at most subclavate, the club 

 conical, strongly obliquely truncate from beneath, often 

 white, the scape cylindrical, not at all dilated ; front wings

Marginal vein not punctiform, although short, the stigmal and postmarginal 

 veins long, very much longer than the marginal.
