1 62 Cameron, Hymenoptera Orientalia. 



in the centre at the base is a distinct fovea, slightly longer 

 than it is wide, and triangular at the apex ; the keels in 

 the centre at the base are oblique ; the apical prolonga- 

 tion slightly oblique and not so straight, and united to a 

 keel at the end ; the apex has an oblique slope and is 

 stoutly keeled all round. All the pleurae smooth and 

 shining ; below the tegulae largely tuberculate ; the centre 

 of the mesopleurae at the base roundly projecting ; in the 

 middle at the apex is a sharp, slightly oblique, short 

 furrow ; the metapleurae at the top roundly projecting ; 

 the base behind the spiracles obscurely punctured ; the 

 central keel narrow, but distinct. Legs stout ; the base 

 of the hinder tibiae, all the claws and the apices of 

 the four hinder tarsi, black. Wings clear hyaline, except 

 at the apices where there is a distinct, narrow, smoky 

 cloud ; the areolet small, triangular, distinctly appendicu- 

 late at the top ; the recurrent nervure is received in the 

 apical third. Petiole at the base smooth and shining ; 

 the apex obscurely punctured ; the apical part at the base 

 with a shallow depression in the middle, rounded at the 

 apex ; the oblique furrow at its apex not very clearly 

 defined, obscurely striolate, the second and following 

 segments coarsely punctured, running into obscure stria- 

 tions on the apices ; the transverse furrows striolated. 

 Shortly beyond the middle of the petiole is an interrupted 

 black line, narrowed on the inner side ; the line on the 

 second is broad and entire ; on the third there is none ; 

 on the fourth is a broad line, interrupted in the middle ; 

 on the sixth the black line is complete, and slightly 

 narrowed in the middle at the apex ; the sheaths of the 

 ovipositor black. 



II. Abdomen with black marks, and with only a black 

 transverse line on the penultimate.
