46. Thorax without a. scaly pubescence and ivithout white lunulte before the tegulte . 47 

 Thorax with a scaly pubescence and with white lunuhe before the tegulse. 



Flagellum elongate, the funicle joints long, excised or subexcised at apex 

 with whorls of long hairs (63) Blastothrix Mayr. 



47. Scape normal, not expanded or dilated beneath, at the most subclavate; wings 



hyaline 48 



Scape usually dilated or expanded beneath, or at least with a carina, rarely 

 simple, unlike the female; wings fuscous or subfuscous, 

 with transverse hyaline bands, rarely hyaline. 

 Thorax smooth but microscopically coriaceous, with sparse jjuuctures scat- 

 tered over the surfaice; frons with a series of puuctui'es, 

 especially on the orbits (64) Microterys Thomson. 



48. Thorax finely coriaceous, subopaque, without punctures scattered over the sur- 



face; frons punctate ; scutelinm with a delicate impressed 

 median line; wings pubescenct, with an oblique hairless 

 line from base of stigmal vein; flagellum subfiliform, 

 clothed with a short, dense pubescence, the funicle joints 

 a little wider than long. 



(65) Holcencyrtus Ashmead, new genus. 

 Thorax smooth, impuuctate, or at the most microscopically reticulate, or with 

 fine longitudinal striae on the mesonotum. 

 Mesonotum smooth, impuuctate, or at the most microscopically reticulate. 49 

 Mesonotum with fine longitudinal striae. 



Stigmal vein scarcely longer than the marginal, the postmarginal vein 

 longer than the marginal and stigmal veins united; eyes 

 pubescent (66) Ageniaspis Dahlbom. 



49. Stigmal vein very short, not or scarcely so long as the marginal and postmarginal 



veins united; axillte meet at their inner basal angles . 50 

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

 and postmarginal veins united ; axillae do not quite meet 

 at their inner basal angles. 

 Antennai with the scape rather short a.nd 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. 



(67) Fseudeneyrtus Ashmead, new genus. 



Antenn^e with the scape long, slender, reaching to or beyond the front ocelli, 



the flagellum elongate, filiform, the funicle joints more 



than twice longer than wide, with long sjiarse hairs; 



scutelinm shagreened or striate. 



(64) Microterys Thomson (part). 



50. Stigmal vein not longer than the marginal and postmarginal veins united, usually 



distinctly shorter, the postmarginal very short, or shorter 

 than the stigmal.. .(68) Epiencyrt^is Ashmead, new genus. 

 Antennie with the scape short, not extending beyond the middle of the face, 

 the flagellum filiform, sparsely pilose, the funicle joints 

 about two and a half times as long as thick; lateral ocelli 

 about or nearly twice their width from eye margin. 



(69) Syrphophagus Ashmead, new genus.
