15. Scape short, subglobo.se; first joint of the flagelluin twice as long as the iM'dicd; 



abdomen oblong, segments 3-5, with transverse grooved lines or fur- 

 rows; metathoracic spiracles minute, inconspicuous, placed before the 

 middle (1066) Myomma Brulle. 



16. Mesonotal furrows complete and only slightly (converging posteriorly; scutellum 



convex, with a crenate furrow across the base; first and second abdom- 

 inal segments coarsely rugose, occu])ying most of tlu^ surface; the second 

 and the third very large, closely united; the fourth and fifth very short, 

 opaque, shagreened; the sixth often retracted, but emarginate medially 

 at apex for the reception of the ovipositor; scape subglobose, truncate 

 at apex; pedicel annular, wider than long; first three joints of the 

 flagellum about of an equal length, scarcely longer than thick. (Japan. )

17. Abdomen normal, vol spinous 18 



Abdomen abnormal, spinous. 



H(!ape long, angulated beneath ( 1068) Binarea Brulle. 



18. Frons flat, not or scarcely impressed a])ove the insertion of the antennae; meso- 



pleura without a furrow. 



Abdomen smooth, as in Maaodyctmm, or at the most with segments 1-3 finely

 abdomen; scape subglobose, very little longer than thick, the first 

 slightly the longest; first dorsal segment with two furrows which con- 

 verge anteriorly; last joint of hind tarsi distinctly shorter than the sec- 

 ond ( 1069) Microhracon Ashmead. 



Abdomen with all the segments, except sometimes the apical segments, sculp-

 first joint of the flagellum distinctly longer than the second, the third a 

 little shorter than the second; first dorsal segment of abdomen rarely 

 much longer than wide at apex, with a depression and a sulcus at base; 

 last joint of hind tarsi long, as long, or nearly, as the second.

19. First discoidal cell jjetiolate; head, thorax, and abdomen most frequently coria- 



ceous or shagreened, rarely smooth and shining; antennal characters as 

 in Bracon {Sensu dricti); ovipositor short, rarely two-thirds the length

20. Mesothoracic furrows more or less distinctly impressed, the middle lobe promi- 



nently elevated anteriorly; scutelum with a crenate furrow across the 

 base. 



Abdomen with the sutures between the segments distinct, well defined; 

 tarsi normal, the last joint of the hind tarsi not enlarged, shorter than 

 the second joint; first joint of the flagellum about twice as long as 

 thick, not or scarcely longer than the second; ovipositor either long or

 abnormal, the last joint much enlarged, as long as the first; first joint 

 of the fiagellum about thrice as long as thick, a little longer than the
