Hymenoptera Orientalis. 241 



Antennae subclavate, the flagellum thin at the base ; the 

 third joint more than twice the length of the fourth. Eyes 

 large, reaching to the base of the mandibles, distinctly con- 

 verging there, and coarsely facetted. Ocelli almost forming 

 a triangle ; separated from each other by twice the length 

 that the posterior are from the eyes. Clypeus moderately 

 convex, the apex margined, almost transverse. Meso- 

 sternum without a keel. Basal area of the median segment 

 smooth, shining, glabrous, and limited by a narrow indistinct 

 furrow. Petiole nodose, clearly defined from the second seg- 

 ment, which, at the extreme base, is equal in breadth to it, 

 but from there it becomes much wider. Abdomen elongate, 

 longer than the head and thorax united. Pygidial area 

 clearly limited, covered with short, depressed, coarse, bristle- 

 like hairs, and apparently longitudinally striolated ; the sides 

 margined. The second cubital cellule at the top is not very 

 much shorter than the third ; and more than the length 

 bounded . by the recurrent nervures ; the first transverse 

 cubital nervure is angled, near the middle. Fore tarsi and 

 tibise spinose.
