50 Cameron, Hymenoptera Orientalia. 



strongly punctured ; thickly covered with long, white 

 hairs ; a straight, narrow furrow runs from the ocelli to 

 the antennae ; the hair on the sides longer and thicker 

 than on the vertex. The scape of the antennae covered 

 with longish, stiff, black hairs ; the flagellum glabrous. 

 Thorax black; the pro- and meso-notum and scutellum 

 strongly punctured ; the pronotum thickly covered with 

 long, white hair. The edges of the pronotum on either 

 side project into a large, sharp plate, the base of which 

 projects into a sharp, triangular tooth. Metanotum at 

 the base with a strongly reticulated area, which, at the 

 apex, is narrowed and runs into a wide, deep, and smooth 

 furrow, slightly narrowed towards the apex and bordered 

 by stout keels ; on either side of this furrow it is smooth ; 

 on the outer side it is apparently punctured, but the 

 punctuation, if present, is hidden by a thick covering of long, 

 white hair. Propleurae almost impunctate, at the apex 

 thickly covered with long, white hair ; the mesopleurae 

 coarsely punctured, the punctures large and clearly 

 separated ; an obscure, vertical furrow down it behind 

 the tubercles, and an oblique, longitudinal one above the 

 middle ; the metapleurae finely and closely rugose ; a few 

 oblique, short keels above the coxae. Legs black ; the 

 calcaria pale ; the femora sparsely covered with longish, 

 white hair ; the tibiae and tarsi thickly with shorter pale 

 hair, which has on the tarsi a fulvous tint. Wings dark 

 fuscous, with a violaceous tinge ; the base paler, the apex 

 from the end of the radial cellule hyaline; the stigma and 

 nervures black. Abdomen smooth, almost shining ; all 

 the segments fringed with a dense band of depressed, 

 white pubescence ; except the last, which is closely punc- 

 tured ; the apical three segments sparsely covered with 

 black hair ; the ventral segments fringed with white pubes- 

 cence ; the hypopygium very smooth and shining; its 

 sides at the apex fringed with long, white hair.
