(J. — Lengtli 6.5 mm. Black, sliining ; 

 the tibial spurs, the extreme apex of the first 

 joint of the anterior tarsi and joinls 2 and 3 

 entirely, and joints i to 3 of middle tarsi, 

 yellowish-white. The clypens at apex medi- 

 ally is subproduced and clothed with a dense 

 silvery pubescence ; the mandibles and the 

 mesopectus with sparse silvery hairs. The 

 head is quadrate, smooth above, but anteri- 

 orly it is sparsely, minutely punctate and 

 with a median grooved line; the eyes are 

 large and converge anteriorly ; the ocelli are 

 arranged in a triangle, the space between the 

 margin of the eye and the lateral ocelli being 

 greater than the space between them. Man- 

 dibles black, bidentate. The pronotum is 

 not short and has a deep transverse impres- 

 sion above, the hind m.argin having a deli- 

 cate median notch which conforms to a deli- 

 cate median grooved line on the anterior 

 half of the mesonotum ; both of these scler- 

 ites are smooth and shining, although with a 

 high power lens one can detect sparse, micro- 

 scopic punctures scattered ovoi' the surface. 

 The met.ithorax above is smooth, polished, 

 with a broad median groove and an oblong 

 area on each side of the groove; the poste- 

 rior face of the metathorax is transversely 

 regulose. the pleui'a striate. The wings are 



liyaline, witli a faint fuscous tinge, the stigma 

 and veins being brown, the stigma and costal 

 vein dark brown; the recurrent nervure 

 unites with the cubital cell just beyond its 

 middle. Tlie abdomen is a little longer than 

 the head and thorax united, subclavate, 

 smooth and shining, but with a high power 

 lens, exhibits, particularly on the second and 

 third dorsal segments and the base of "the 

 third, very fine, delicate, transverse acicu- 

 lations.
