40 Cameron, Hymenoptera Orientalia. 



the scape of the antennae reddish beneath ; the thorax 

 almost bare, the scutellum wanting the thick mass of 

 white hair at the apex entirely ; while the apex looked at 

 from above is seen to be stoutly bidentate ; instead of 

 being uniformly rugosely punctured, the punctures are all 

 widely separated, while at the base in the middle there is 

 a large shining impunctate space. 



Head rugosely punctured, sparsely covered with white 

 hair ; the clypeus shining, impunctate, glabrous, with two 

 elongated punctures on either side of the middle ; and 

 there is a shining, impunctate spot above it. Base of 

 mandibles finely longitudinally striated ; the centre 

 broadly rufous. Scape of antennae rufous, darker at the 

 apex ; the flagellum stout, thickly covered with short 

 white hair. Pro- and meso-notum with large deep punc- 

 tures ; the scutellum also strongly punctured ; the centre 

 at the base with a large smooth, impunctate space, 

 surrounded by large shallow widely separated punctures ; 

 its apex ending in large teeth, rounded at the points ; 

 the median segment strongly reticulated. Propleurae at 

 top finely shagreened ; its lower part and sides behind 

 irregularly reticulated ; the mesopleurse shining ; at the 

 base on the lower side with some large deep punctures, 

 this basal part being separated from the larger posterior 

 by a distinct keel ; the metapleurae coarsely rugosely 

 punctured, and in front thickly covered with long white 

 hairs. Legs : the four anterior coxae and trochanters, 

 black ; the four anterior femora broadly black at the 

 base ; the apex white ; the tibiae and tarsi white : the 

 former broadly lined with black at the base ; the hind 

 coxae, trochanters and femora red. The tibiae and tarsi 

 white, like the anterior, the tibiae broadly black in the 

 middle ; the femora with 10 minute black teeth. Abdo- 

 men very smooth and shining ; the penultimate segment 

 aciculate, and bearing large deep round punctures.
