as long as tlie first joint of funicle, or possibly slightly longer ; in % 

 with the flagellinn filiform, the elongate, cylindrical and pilose joints, 

 varying in length from two to three times as long as thick, the basal 

 joint the longest. Thorax ovoid, the pronotuin not especially short, 

 about two-thirds as long as the mesonotum, rounded off antei'iorly ; 

 niesonotum alxnit twice as wide as long, with the parapsidal furrows 

 indicated anteriorly ; scuiellum convex, a little longer than wide, 

 with a delicate transverse grooved line before the apex, the axillse 

 nearly as wide apart as their width at base, the postscutellum dis- 

 tinct and rather large, punctate, nearly as long as the apical part 

 of the scutellum beyond the transverse suture ; metanotum without 

 spiracular sulci or carinne, closely punctate, somewhat deeply sinuate 

 on each side of the middle posterioi-ly, the spiracles small, rounded ; 

 front wings with the postmarginal and marginal veins about equal 

 in length, the latter not quite one and a half times as long as the 

 stigmal and nuich thicker at base than at apex, the stigmal vein 

 ending in a small knob with an uncus. Legs normal, the tibial 

 spuro 1, 1, 1. Abdomen in 9 conic-ovate, as long as, or a little 

 longer than the head and thorax united ; the second segment, which 

 is the longest, occupies scarcely one-third of the surface; the third 

 segment is the shortest ; the fourth and fifth longer, increasing in 

 size, the fifth being nearly twice as long as the third, the sixth is 

 about as long as the fourth ; the seventh and eighth a little longer, 

 the latter conical, with distinct spiracles ; the tips of the ovipositor 

 sheaths project a little beyond the eighth, while the sides of segments 

 4-8 are fimbriate. In the % the abdomen is oblong, hardly as long 

 as the thorax, the second segment occupying about half, or some- 

 times more than half of the whole surface, the three following seg- 

 ments subecjual, the terminal segments very short. 



This new genus belongs to the tribe 3/erwi>u', distinguished from 

 other Pteromalids by the absence of si)iracnlar sulci.
