81. Stiginal vein very short, not or scarcely so long as the marginal and postmaiginal veins united ; axilhe 



meet at their inner basal angles 82 



Stigmal vein much longer than the marginal, as long or longer than the marginal and jmstmaginal 

 veins united ; axillae do not quite meet at their inner basal angles. 



Antenna; with the scape rather short and stout, not reaching to the front ocelli, the flagellum 

 elongate filiform, clothed with sparse moderately long hairs, the funicle joints about thrice as 



long as thick, or nearly Pseudencyrtus Ashniead. 



Antenna; with the scape long, slender, reaching to or beyond the front ocellus, the flagellum elon- 

 gate filiform, the ftinicle joints more than twice longer than wide, v\ ith long sparse hairs ; scutel- 

 lum shagreened or striate Microterys Thomson (part). 



82. Stigmal vein not longer than the marginal and postmarginal veins united, u.sually distinctly shorter, 



the postmarginal very short, or shorter than the stigmal Epiencyrtus Ashmead. 



AntenuiE with the .scape short, not extending beyond the middle of the face, the flagellum fili- 

 form, sparsely pilose, the funicle joints aljout two and a half times as long as thick ; lateral 



ocelli about or nearly twice their width from the eye margin Syrphophagus Ashmead. 



Stigmal vein very short, not so long as the marginal and postmaginal united, the foi-mer being not more 

 than or hardly twice as long as thick, the postmarginal never well developed, although acuminate 

 and longer than the short marginal. 



Flagellum filiform, pilcse, the joints of funicle about twice as long as thick ; lateral ocelli 

 at least their width from eye margin Aphidencyrtus Ashmead. 



83. Scutellum neilher triangular nor acute at apex 84 



Scutellum triangular, acute at apex. 



Antennie simple, subfiliform, pubescent Choreia Westwood. 



84. Funicle 6-jointed 85 



Funicle 2-jointed, the club unusually long and cylindrical (teste Mayr) Habrolepis Fcirster. 



85. Head with vertex antero-posteriorly broad, the face much inflexed, the frous regularly punctate ; an- 



tennse with the scape and flagellum usually strongly compressed, broad ; wings fuscous or with fus- 

 cous rays 86 



Head always semiglobo.se, the face less distinctly inflexed, the scrobes always forming a semicircle ; 

 antenna; simple, filiform, the joints long, cylindrical, distinctly separated and haiiy, rarely slightly 

 compressed ; wings usually fusco-radiate or partly fuscous, rarely entirely hyaline. 



Scape elongate, extending to or beyond the front ocellus, the flagellum very long, clothed 



with rather long hairs Cheiloneurus AVestwood. 



8G. Wings fuscous, with nariow white tips 87 



Wings hyaline, the marginal vein rather long, stout, as long as the stigmal vein, the latter not short, 

 the postmarginal not developed ; antenmu long, filiform, the flugelluni with si)arse modei'iitely long 

 hairs ; funicle joints 1-G constricted at apex or subpedunculate, soiiitwliat similar to the male in 

 Euryloma Cerapterocerus AVestwood. 



87. Marginal vein shorter than the stigmal 88 



Marginal ^'ein longer than the stigmal. 



Facial impression not bounded by a distinct carina superiorly Eusemion Dalillion). 



88. Facial impression and .scrobes deep, bounded by a high carina superiorly. 



Scutellum with a tuft of bristles ; stigmal and postmarginal veins very lun.u. 



Chrysoplatycerus Ashmead. 



Scutelluiii irilliiiut a tuft of bristles ; sliguuil and postmarginal veins not long. Anicetus Howard. 



Facial impre.s.siun not liuuuded by a carina superiorly Zarhopalus Aslniicail.
