and mandibles reddish browu. Head circularly striate, the uhindibles as in Orascma. Thorax 

 uniformly rugoso-punetate, the scutellum obtuse at apex. Parapsidal furrows complete, 

 punctate. Dorsum of thorax plane. Abdomen large, comjjressed, upturned, the petiole some- 

 what longer than the hind coxa. Metatarsus slender. Scape somewhat shorter than fnniele I, 

 distinctly longer than wide, the pedicel short, wider than long; funicle 1 longest of the 

 antenna;, widening distad, one and a half times longer than wide at apex, or that many times 

 longer than funicle 2, which with the following joints are no longer than wide at apex, 

 narrower at base, becoming smaller toward apex, the simple club joint a little longer than 

 funicle 2 (in one antenna the distal funicle joint was fused with the club) ; funicle joints armed 

 around apex with several short, nipple-like tubercles. Antennie 11-jointed, no ring-joint.

Genus EPIMETAGEA Girault. 



Synonym : Astilhula Girault. 



The same as Metagea Kirby but the antennae not moniliformi and only 10- jointed.. 

 Also agreeing somewhat with Pseudochalcura Ashmead but differing again in lacking one 

 antennal joint. Head thin, triangular, the antennie inserted slightly below the middle of the 

 face, the club solid and ovate, longer than any of the funicle joints but slightly shorter than 

 the simple cylindrical scape; pedicel obconie, short, subequal to joint 1 O'f the funicle, bearing 

 from one side of its apical margin a single, very long, slender but stiff bristle-like seta which 

 reaches distad nearly to the apex of joint 3 of the funicle. Proximal funicle joint longest, 

 nearly twice the length of the pedicel, all the funicle joints obconie, widening distinctly 

 distad, all more or less prolonged obtusely from one apical corner, the distal joints more so. 

 None of the joints petiolate or subpetiolate ; no ring-joint. MandiMes long and falcate, acute 

 at apex, the right with two large triangular teeth within, tlte left with one that is larger 

 than either of those of the right; also exteriorly at base each with a large tooth. From 

 beneath the clypeus there projects a flat, palmate (9-digitate), brownish plate, above and 

 between the mandibles; clypeus convex along its distal margin, the latter with two teeth on 

 each side of its end, the first very obtuse, the second more toothlike but not large. Ocelli 

 nearly in a straight line across the short vertex, the cephalic one within and at the apex of 

 the short scrobicular cavity. Parapsidal furrows complete, with deep punctures. Scutellum 

 normal, terminating in a short plate whose distal margin is entire though convex. Thorax 

 elevated convexly in places but the convexities obtuse. A rather large toothlike plate from 

 the lateral aspect of the thorax some distance ventrad of the axilla. Thorax with large 

 irregular reticulations or narrow carinate lines, but not punctate except the large i)unctures 

 in sutures. Abdomen with a distinct petiole (which is moderate in length), depressed, diamond- 

 shaped from dorsal aspect, opaque. Petiole somewhat over twice longer than wide. Proximal 

 tar,sal joints of all the legs long .and slender hut the first tarsal joints are not half the 

 length of the tarsi. Venation obscure, the stigmal and postmarginal veins short, much 

 shorter than the marginal, the stigmal the longer- of the two, curved or bent like a boomerang. 

 Wings hyaline, all cihation nearly absent ; a trace of marginal cilia disto-caudad. From 

 lateral aspect, scutellum appearing as if terminating in a short acute tooth. The axilla! meet 

 mesad.
