200 Cameron, Hymenoptera Orientalia. 



the clipeus semicircular above, slightly depressed, sparsely 

 punctured, foveate at the sides above ; its apex transverse, 

 rounded at the sides. The inner orbits above distinctly 

 margined ; at the top of the eyes there is a distinct furrow; 

 between the antennae is a rounded keel; the front is 

 depressed in the middle; the sides are closely punctured; 

 the vertex sparsely punctured, black ; the ocellar region 

 being also black and, behind, the black extends on to the 

 upper part of the occiput. Mesonotum strongly punc- 

 tured ; on the apex of the middle lobe is a large black 

 mark, gradually narrowed and rounded to the apex ; its 

 base trilobate, the middle lobe the smaller ; the lateral 

 lobes are broadly black from near the base and are united 

 at the apex at the scutellum. Scutellum with a rounded 

 slope at the base and apex ; strongly punctured, covered 

 with long, fuscous hair ; its apex bears a large black mark, 

 rounded at the base. Postscutellum impunctate, shining, 

 almost glabrous. The base of the median segment is 

 black in the three basal areai which are punctured, smooth 

 at the base ; the middle area is broader than its length, and 

 rounded at the apex ; from its sides runs a short, oblique 

 keel ; from the middle a shorter, straight one, and outside 

 the oblique keels is a shorter one, also oblique ; the apex 

 is very smooth, its sides keeled, with a short, elongated area 

 joined to it on the inner side at the top; inside this, near 

 the base, is a short curved, transverse keel. Propleurae 

 strongly punctured, except in the middle, the lower side 

 strongly obliquely striolated. Mesopleurae strongly and 

 closely punctured, except on the apical half near to the 

 apex ; the apex itself is raised and closely punctured ; on 

 the middle, at the apex, is an oblong black mark. Meta- 

 pleurse closely punctured, between the two keels bordering 

 the spiracular region stoutly irregularly striolated. Meso- 

 sternum closely punctured, and thickly covered with pale
