mesopleurae sparsely clothed with wliite pubescence, a vertical 

 carina below the anterior wings joining a wide shallow 

 vertical groove, a few very short horizontal strife behind the 

 carina. JNIedian segment short, the basal area shorter than 

 the scutellum and strongly longitudinally striated, a deep 

 groove running from the apex ot the basal area to the apex 

 of the segment, which is very steeply sloped behind the basal 

 area and very coarsely rugose. Petiole as long as the thorax 

 without the median segment, not grooved or carinated ; the 

 abdomen shining, very minutely punctured, the four apical 

 segments with sparse, short, grey pubescence. Pygidial area 

 well defined, elongate-triangular and very coarsely punctured. 

 First recurrent nervure received before one-third from the 

 base of the second cubital cell, the second received by the 

 third cubital cell very near the base ; the second cubital cell 

 not more than one-third of the length of the third on the 

 radial nervure. 



Black ; the tegulse, intermediate and anterior tarsi, the 

 base of the intermediate and anterior tibiae, and the spines 

 of the tibiae and tart«i testaceous ; the apex of the first abdo- 

 minal segment most broadly on the sides and the sides of 

 the second f'eiTuginous. Wings hyaline, nervures black, the 

 stigma fusco-ferruginous. 



1^ . As in the female, but the petiole is slightly longer and 

 the ferruginous colour is more extensive on the second dorsal 

 segment ; the apical joint of the antennae is light brown.

 Long. 8-9 mm, 



? . Clypeus vei'y finely and closely punctured, thickly 

 clothed with silvery-white pubescence, more than twice as 

 broad as long, the anterior margin nearly straight, with two 

 small teeth near the middle. Antennae inserted a little 

 further from each other than from the eyes, and separated 

 from the base of the clypeus by a distance equal to the length 

 of the clypeus, gradually thickened to the apex, shorter 

 than the thorax and median segment combined ; the second 

 joint of the flagellum nearly as long as the first and third 

 combined ; a very nai'rowly V-shaped carina between the 

 antennae, which extends to a transverse feebly arched carina
