apex. The anterior margin of thepronotum raised with a groove 

 behind the elevation, broadly emarginate. The thorax punctured, 

 the mesothorax and scutellum most coarsely. Median segment 

 punctured, rounded to the apex. Abdominal segments shallowi y 

 punctured; a transverse impressed line, with a row of fine punc- 

 tures on the basal side of it, near the base, and a raised mark on 

 each side near the apical margin of segments 2-6. Epipygium 

 deeply punctured, the apical margins strongly recurved. Entirely 

 black, with white pubescence. Wings hyaline, primaries faintl}' 

 fusco-hyaline on the apical third, secondaries iridescent. Length 

 (S-IO mm. 



9. Head quadrate, as broad as long, slightl}^ rounded at the 

 posterior angles, densely and finely punctured, with thin cinereous 

 pubescence, a deep semicircular depression on the middle of the 

 posterior margin. Prothorax short, broader than long, with the 

 anterior lateral angle on each side produced into an acute spine, 

 and a depression on each side of the posterior ma? gin, extending 

 on to the mesothorax. The mesothorax raised in the middle into 

 a rounded subtubercular elevation. Median segment rather 

 short, broadened to the apex, where it is almost vei tically trun- 

 cate, with a broad median carina, and the margins of the segment 

 raised, leaving a deep depression on each side of the median 

 carina. The thorax and median segment shining, sparsely and 

 finely punctured. Abdomen subcylindrical, finely and densely 

 punctured, the punctures on the apical half of each segment 

 elongate. The second and third segments are more densely 

 punctured than the others and are thinly clothed with fine pubes- 

 cence on the apical half, giving an appearance of longitudinal 

 stride. Enipygium elongate, strongly detlexed to the apex, with 

 a very slender acute spine at the side near the base, the lateral 

 margins on the apical half of the segment raised into carinas, the 

 space between them longitudinally striated to the apex, which is 

 narrowly rounded. Black; antennie, mandibles, legs and abdomen 

 chestnut-brown. Length G-8 mm.
