Female. — Length 1.8 to 2 mm. Most variable in color, metallic 

 bluish-green, aeneous or bronzed green, with bluish, purplish and brassy 

 reflections, the parapsides, mesopleura and metathorax, most frequently 

 bluish or blue-black, faintly tinged with metallic green, the head, pro- 

 thorax and at least the middle mesothoracic lobe metallic green or brassy ; 

 abdomen most frequently aeneous black, sometimes with a decided 

 brassy tinge ; scape, pedicel and legs, except sutures of trochanters, tips 

 of femora, the tibiae and the tarsi except as hereafter noted, aeneous 

 black or metallic ; the sutures of trochanters, tips of femora, the tibiae, 

 except apices of the middle and hind tibiae, and the tarsi, except last 

 joint, honey-yellow or brownish-yellow ; tips of middle and hind tibiae 

 and the last joint of the tarsi dark brown or fuscous ; the middle tibiae 

 sometimes before the middle are more or less obfuscated ; the flagellum 

 black or brown-black, sparsely pubescent ; tegulze testaceous or yellow- 

 ish ; wings hyaline, the venation brown ; the stigmal vein with its club 

 is rather long, but a little shorter than the marginal, the club being 

 large and with a small uncus obliquely directed towards the margin of 

 the wing, and if continued would form a triangular marginal cell ; the 

 postmarginal vein is very long, nearly twice as long as the marginal. 



The head is transverse, a little more than thrice as wide as thick 

 antero-posteriorly, much wider than the prothorax and possibly a little 

 wider than the mesothorax from tegula to tegula ; viewed from in front 

 it is a little wider than long, obtusely triangular ; posteriorly it is smooth, 

 on the vertex and anteriorly it is feebly alutaceously sculptured ; ocelli 

 small, arranged in an obtuse triangle ; eyes oblong-oval ; the malar space 

 distinct, at least one-third the length of the eye ; clypeus small, obtrap- 

 ezoidal, indistinctly separated, and indistinctly bidentate anteriorly or 

 with a slight median incision; mandibles (?) 4-dentate. 



The antennae are 13 -jointed, with 2 minute ring-joints inserted near 

 the middle of the face above a line drawn from the base of the eyes ; 

 the scape is about as long as the first three funicle joints united ; pedi- 

 cel obconical, scarcely longer than thick at apex; the flagellum is sub- 

 clavate, thrice as long as the scape, with the joints all delicately fluted, 

 the funicle being 6-jointed, the joints oblong, about one and a half
