BRUES: PARASITIC HYMENOPTERA. 123 



furrow; cheeks wide, but temples very narrow; eyes bare, convergent 

 on the front above; oceUi large, in a small equilateral triangle, sepa- 

 rated from one another by their own diameter, but almost touching 

 the eye. Mandibles broad, tridentate. Antennae with long, cylin- 

 drical scape, nearly as long as the eye-height; first flagellar joint 

 over twice the length of the pedicel and over one third as long as the 

 scape; second flagellar joint wider, twice as long as wide; third wider, 

 quadrate, fifth and following which form the rather slender club trans- 

 verse, those near the middle of the club twice as wide as long. Thorax 

 and scutellum above very coarsely punctate, the punctures forming 

 longitudinal rugae on the sides of the pronotum and a more or less 

 distinct row just outside the well-marked parapsidal furrows; no 

 median furrow on mesonotum, although there are two short indistinct 

 ridges anteriorly between the parapsidal furrows. Scutellum rounded 

 behind ; postscutellum unarmed, visible only as a series of deep foveate 

 punctures under the edge of the scutellum. Propodeum medially 

 raised almost to the level of the scutellum as a triangular portion, 

 pointed behind where it is minutely bidentate; on sides below this 

 smooth, followed by a carina below which the surface is concealed 

 by a rather dense coat of short white hair. Propleurae smooth and 

 polished anteriorly, white, hairy on the posterior strip; mesopleura 

 with a smooth oblique depression, below and anteriorly coarsely 

 strigose, behind with a series of foveae, hairy in front; metapleura 

 rugose-reticulate beneath the hair which is less dense than that on the 

 lower part of the propodeam. Abdomen about half longer than the 

 head and thorax together, with six visible segments; first as long as 

 wide, but little narrowed basally, coarsely longitudinaUy striate; 

 second and third segments of equal length and similar sculpture, the 

 third quadrate, but the second narrower basally; surface longitudi- 

 nally striate-reticulate, with series of fine punctures between the reticu- 

 lations, laterally with a sharp carina which extends also along the 

 sides of the first and fourth segments; medially with a raised line 

 which extends over the fourth segment and indistinctly beyond; 

 fourth segment slightly shorter than the third, quadrate, similarly 

 sculptured; fifth as long as wide, considerably narrowed behind, the 

 lineate sculpture less evident, sixth small, triangular, entirely without 

 lineations but retaining the punctures; all sutures smooth, impunc- 

 tate; venter coarsely, sparsely punctate, much more convex than the 

 dorsum. Legs rather slender, the tarsal claws simple. Marginal 

 vein rather long, about five or six times as long as thick; stigmal 

 oblique, knobbed, nearly one third longer than the marginal; basals,
