Ii8 Cameron, Hymenoptera Orientalia. 



covered with long, black hair; the flagellum thickly with 

 a black, microscopic pile. Front and vertex bearing 

 widely separated, shallow punctures, thickly covered with 

 short, .blackish hair ; in the centre, between the ocelli, is a 

 shallow furrow ; the face and clypeus, except at the apex 

 strongly punctured ; the mandibles are coarsely punctured ; 

 before the teeth is a large, dirty testaceous mark, which is 

 sharply oblique at the base; the palpi fulvo-testaceous. 

 Thorax entirely black ; the mesonotum closely, but not 

 strongly, punctured; on the sides at the apex are two 

 shallow, indistinct furrows ; the scutellum is more strongly, 

 more rugosely, punctured ; the postscutellum is flat, rugose, 

 the sides carinate. The median segment at the base is 

 finely rugose; from its centre run two curved keels, from 

 the middle of which runs a deep and wide depression to 

 the apex of the segment; the entire apex before the keels 

 is transversely, at the apex more obliquely, strongly 

 striated, and thickly covered with white hair; from near 

 the apices of the two basal keels run stout, curved keels; 

 at the base of this, on the inner side, are two short keels, 

 and on the outer side two longer, oblique ones. The base 

 of the propleurae strongly aciculated ; the hollowed middle 

 strongly obliquely striated ; the lower striations stronger 

 than the upper. Mesopleurae punctured; on the upper 

 edge it is raised; the middle acutely keeled; above the 

 keel, bearing curved striations; below it, at the base, 

 strongly obliquely; the middle with a few stout keels; 

 the apex regularly marked with curved striations; the 

 lower part at the base with stout, longitudinal striations; 

 the apex is depressed, crenulated. The base of the meta- 

 pleurae is irregularly rugose ; the oblique furrow deep, 

 irregularly crenulated; at the base is an almost smooth, 

 clearly defined, flat, shallow furrow; the upper half is 

 strongly obliquely striated, the lower closely rugosely
