 joints of the funicle cylindrical, much longer than wide, 

 never niouiliform; abdomen conic-ovate, usually a little 

 longer than the head and thorax united. 



(67) Pseudencyrtus Ashmead, new genus. 



22. Stigmal vein not longer than the marginal and postmarginal veins united, usu- 



ally distinctly shorter, the postmarginal vein very short 

 or shorter than the stigmal. 



Club of antenuiu much enlarged, usually as long, longer, or nearly as long 

 as the funicle, and obliquely -truncate from beneath, the 

 joints of the funicle, or at least the first three or four 

 joints, moniliform, or not longer than thick, the others 

 transverse, broader than long; abdomen ovate, rarely 

 longer than the head and thorax united, most frequently 

 the length of the thorax or a little longer. 



(68) Epiencyrtus Ashmead, new genus. 



Club of antenna^, not much enlarged, nor obliquely truncate from beneath, 

 fusiform, and less than half the length of the funicle, none 

 of the funicle joints wider than long; abdomen short 

 ovate, hardly as long as the thorax. 



(69) Syrpliophagus Ashmead, new genus. 

 Stigmal vein very short, scarcely so long as the marginal and. postmarginal 

 veins* united, the former being not more than or hardly 

 twice, as long as thick, the postmarginal never well devel- 

 oped, although acuminate and longer than the short mar- 

 ginal; club of antouute oblong, stouter, and a little more 

 than half the length of the funicle, the first two or three 

 joints of the funicle short or moniliform, the following 

 usually a little longer than thick, or, at most, with only 

 the last two joints a little wider than long; abdomen 

 broadly oval and considerably shorter than the thorax; 

 scutellum variable, subopaquely sculptured or polished, 

 impunctate, the axillte not quite meeting at their inner 

 basal angles (70) ApMilencyrtus A.shm.&Sh(\., new genus. 



23. Winged species 24 



Wingless. 



Scutellum triangular, acute at apex, not declivous, antennie simple, the 

 scrobes deep . , (71) Choreia Westwood. 



24. Head with the face much iuflexed, the scrobes deep, semicircular, the frons 



most frequently regularly punctate 25 



Head always semiglobose, the face less distinctly iuflexed, the scrobes, however, 

 always forming a semicircle; antennae simple or at least 

 never much compressed nor A^ery broad, subcylindrical; 

 wings not fusco-radiate; scutellum with a clump of hairs 

 at apex (72) Chetloneurus Westwood. 



25. Wings fuscous, usually with the extreme tips white or hyaline 27 



Wings with fuscous rays 26 



Wings hyaline, or at most with a discal cloud; antenna^, short. 



Eyes large, rounded, strongly converging above, and leaving a very narrow 

 or linear vertex; antenniE very short, the club enormously 

 enlarged, longer than the funicle and several times thicker, 

 the joints of the funicle transverse.
