2i6 Cameron, Hymenoptera Orientalia. 



recurrent nervure in its apex, almost touching the trans- 

 verse cubital nervure. Abdomen strongly punctured, 

 thickly covered with white hair ; the second segment 

 entirely and the apical two-thirds of the third rufo- 

 testaceous ; at the base of the dilated part of the petiole 

 is a smooth, shining tubercle. 



SCALLAMA, gen. nov. 



Areolet oblique, small, appendiculate to the middle. 

 Antennae stout, short; the third joint elongate, nearly 

 twice the length of the fourth. Mandibles at the apex 

 with one longish apical tooth. Palpi short and thick. 

 Legs short and thick, the femora dilated ; the four hinder 

 tibiae with two spurs ; the hinder large, the outer much 

 larger than the inner, slightly curved, lanceolate ; the 

 hinder tarsi thickly covered with stiff, bristle-like hairs ; 

 the claws large, thick at the base, the apex hook-shaped, 

 curved, sharp. Mesopleurae largely projecting in the 

 middle, the base and apex with an oblique slope. Meta- 

 thoracic spiracles oblique, more than twice as long as 

 broad, rounded at the base and apex. Scutellum flat, not 

 keeled laterally, becoming gradually narrowed towards the 

 apex. Postscutellum large, smooth, flat, depressed at the 

 apex. Petiole broad at the base, becoming gradually 

 wider towards the apex ; the other segments flat ; the 

 spiracles small, round, situated quite close to the base. 



The eyes are large, but do not reach to the base 

 of the mandibles. The head is sharply narrowed behind 

 the eyes, and is not much developed there ; the clypeus 

 is not separated from the face at the top on the inner side, 

 the eyes have a distinct, curved incision ; there are no 

 furrows on the mesonotum, nor keels on the median seg- 

 ment, except on the sides ; the petiole becomes gradually 

 dilated from the base (which is itself broad) to the apex.
