cies.
3. -Length 6,s mm. Black, shining;
the tibia1 spurs, the cxtreme apes of the first joint of the anterior tarsi and joints 2 and 3 entirely, and joints I to 3 of middle tarsi, yellowish-white. The clypeus 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 urge 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, bidental-e. The pronoturn is not short and has a deep transverse impres- sion fibove, the hind margin 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, allhouglh with :t high power lens one c;in detecl sparse:, micro- scopic punctnres scattered over the surface. The metathorax 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 rcgulose, the pleurn striate. The wings are hyaline, with a faintfuscous tinge, the stigma and veins being brown, the stigma and costal vein dark brown; the recurrent nervnre
unites with the cubital cell just beyond its middle. The a"bumen 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 acicii- lalions.
