Family EURYTOMIDAE. 



Genus Bephratoides Girault (nee Brues). 

 This name is preoccupied. For it I propose the new name, 

 Bephratelloides. 



Family PTEROMAUDAE. 



SPHEGIGASTERINI. 

 Polycystoides new genus. 



Female. Like Polycystus Westwood but the antennae only 

 n-jointed, the club solid; moreover, the petiole of the ab- 

 domen is short and stout, the median carina of the propodeum 

 is intersected by a distinct transverse carina from side to side 

 and the cephalic margin of the propodeum is carinated ; the 

 propodeum with a distinct neck and spiracular sulci ; between 

 the median carina and the spiracle along the cephalic margin 

 is a large fovea. Mandibles strongly tridentate ; transverse 

 suture on scutellum faint. Second abdominal segment occu- 

 pying about a fourth of the surface. Propodeum reticulated, 

 the thorax inflexed at the scutellum. Head very large but 

 wider than long. Postmarginal vein longer than the stigmal. 

 Distal margin of scutellum carinated. Antennas with two ring- 

 joints. Abdomen stout, conic-ovate, somewhat longer than 

 the thorax. Axillae widely separated. Parapsidal furrows 

 incomplete. Hind margins of abdominal segments straight. 



Male. Not known.

1. Polycystoides tennysoni n. sp.

Dark blue, opaque and punctate, the wings hyaline, the abdomen 

 shining aeneous green ; legs and antennae yellowish brown but the 

 coxae dark blue and the club (which is enlarged) and distal funicle 

 joint are black. Ring joints stout; first three funicle joints distinctly 

 longer than wide, of them 2 and 3 longest, subequal, each a little 

 shorter than the pedicel ; joint 4 of funicle only a little longer than 

 wide; joints 5 and 6 shortening, 6 distinctly much wider than long.
