point ; the central about 3 times longer than wide, of equal width, the apex with 

 a triangular incision. Central area of metanotum irregularly coarsely aciculated 

 above and with a few oblique irregular striae, below it is smooth and shining, 

 the sides of metanotum aciculated and bearing distinctly separated oblique 

 striae. Mesothorax strongly punctured, the pleurae more strongly than the rest ; 

 down the centre of the latter is a furrow which extends shortly below the 

 middle ; on either side of its lower end is an obscure curved longitudinal 

 furrow. Flagellum rufo-fulvous. Pygidium long, gradually narrowed from the 

 base to the apex, which is rufous ; it is strongly closely punctured. Mandibles 

 broadly pale yellow at the base, a rufous belt beyond the yellow, the apex 

 black. Wings hyaline, the nervures mostly black, tegulae pale yellow. $ . 



Length 6 mm. 



Deesa, December. 



The puncturation is strong, the scutellar central keel is clearly defined ; there 

 is a stouter, less clearly defined one down the centre of the post-scutellum ; the 

 pubescence close, pale. The mucro is hollowed above, not curved. 



Oxybelus fulvicaudis, sp. nov. 



Bla.ck, the abdomen slightly tinged with bronzy colour, the last segment 

 bright fulvous, the greater part of the 4 anterior tibiae, the apex of the posterior, 

 and the tarsi rufo-testaceous ; the base of antennal scape narrowly, and its apex 

 more broadly testaceous, the flagellum rufo-testaceous. Wings clear hyaline, the 

 nervures and stigma fuscous. Scutellar process about 4 times longer than wide, 

 curved, of equal width throughout, the apex with a wide, rounded shallow 

 incision. $.

 side the keel. Metanotal area large, an elongated triangle, extending almost to 

 the apex its sides at the base stoutly obliquely striated, the middle part aci- 

 culated, the apex smooth ; the sides at the top stoutly, obliquely irregularly striat- 

 ed, the apex strongly aciculated, almost punctured. Mesopleurae irregularly 

 rugosely punctured ; there is a wide furrow below the middle, the breast is 

 bordered by a curved crenulated furrow. There is a striated area, bordered at 

 the apex, by a curved furrow ; the apex above is obscurely striated, below it is 

 smooth. Basal segment of abdomen smooth, the rest closely punctured ; the 

 segments laterally covered with silvery pubescence, the pygidium with longish 

 punctures and with silvery pubescence.
