and the metallic-blue scape; mandibles fuscous; venation concolorous 

 with the legs; ventral surface of the petiole pale; wings clear, irride- 

 scent; eyes garnet-red; a large portion of the ventum of the basal half 

 of abdomen, pale, forming a whitish area; face metallic-blue; tibiae of 

 the posterior legs more dusky. Head rounded, at least three times wider 

 than long (dorsal aspect), the whole of the face concaved and mar- 

 ginate, shagreened with sparse whitish hairs ; eyes large, subreniform, 

 with minute hairs. Head wider than thorax. Thorax longer than head 

 and abdomen combined, shagreened, pilose; mesothorax with a deep 

 femoral furrow; on each side, just caudad of the insertion of the 

 posterior wings, a conspicuous tuft of stiff hairs. Portions of the pleurae 

 and the metathorax glabrous. Abdomen ovate, broadest at caudal 

 fourth, pilose, the color somewhat variable in intensity. Segment two 

 longest, twice longer than 3; 3 and 4 equal; 5, 6 and 7 equal, one-third 

 smaller than 3 ; the remaining segments abruptly narrowed, the anal 

 segment acute. Submarginal vein slightly longer than the marginal; 

 postmarginal vein more than one-half as long as the marginal ; stigmal 

 vein distinct. Wings normal. Antennae 9-jointed, hispid, 3-branched, a 

 branch arising from the side of the base of each of the three proximal 

 funicle joints, the proximal branch the longest; ring-joints absent; 

 ramifications of the antennae more hispid. Scape nearly club-shaped, 

 thickest at its middle, nearly as long as the next three joints com- 

 bined; pedicel globate, about one-half the length, or more, of the first 

 funicle joint. Joint I of funicle cylindrical, about one-third the 

 length of the scape and slightly over half the length of the following 

 joint, its ramification more slender, and at least six times its own 

 length; joint 2, the same, nearly twice the length of joint 1, inter- 

 mediate in length between 1 and 3, its ramification slenderer than itself, 

 and at least three times longer; funicle joint 3 twice the length of joint 

 1, slenderer, its ramification about equal to it in width, and at least twice 

 its own length. Funicle joints 4 and 5 slender, equal in width to the 

 ramification of the second funicle joint, about equal in length, both 

 slightly shorter than the scape, and one-third longer than joint 3. Club 

 abruptly thicker, about equal in length to joint 3 of the funicle, com- 

 posed of two closely united and unequal joints. 



From three specimens. 



Female. — Length, 2.2 mm., average. — The same; larger. Color of 

 the ventum of the abdomen more uniform, the large whitish spot more 

 or less indistinct; the thorax and scutellum more strongly shagreened, 

 in fact punctate, the reticulations forming pentagons. Abdomen ovate, 

 wider, broadest at the middle, or at the third segment; second abdo- 

 minal segment much the longest. Scape of antennae pale, the remaining 

 joints dusky. Antennae 9-jointed, including a single ring-joint, cylindri- 

 cal, pilose. Scape long and cylindrical, longer than the first funicle
