behind it. Mesopleura finely punctate above, longitudinally acieu- 

 late below; metapleura irregularly rugose-striate, without any dis- 

 tinct punctures. Posterior tibiae with a few short bristles externally 

 in addition to the pubescence. Submedian cell much shorter than 

 the median; cubito-discoidal cell with a chitinous triangular spot just 

 beyond the middle, prolonged as a thin line nearly to the radial vein; 

 discoidal vein in hind wing broken at lower third.

9 . Length 20 mm. Uniformly pale yellowish brown, without 

 lighter markings and with only the tips of mandibles and tarsal claws 

 black. Wings hyaline, venation piceous. Face and cl\ pens polished, 

 not distinctly punctate; malar space only about half as long as the 

 diameter of the first flagellar joint. Mesonotum minutely punctate. 

 Lateral carina of scutellum straight; scutellum not striate toward 

 apex which is half as broad as the base. Propodeum punctulate and 

 shining before the carina, behind it reticulate, much more finely so 

 anteriorly near the carina. Mesopleura below finely closely punctate, 

 not distinctly striate; metapleura finely densely punctate above, 

 sparsely so below. Hind tibiae without fine bristles in addition to 

 the pubescence. Median cell longer than the submedian; cubito- 

 discoidal cell with two chitinous spots close together, the basal one 

 triangular and joined to the apical, arcuate one by an almost imper-

 third.

There are three specimens of this rather widely distributed species 

 from Fulakora, Auki, and Malaili. Two are quite typical, agreeing 

 in color with the original description and with Papuan specimens, 

 while another is entirely black, except for the antennal scape, an 

 oblique stripe on each side of the front opposite the scape, a spot at 

 the upper angle of the hind coxa, a stripe along the upper edge of the
