 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.

There are three specimens of this rather widely distributed species 

 from Fulakora, Auki, and Malaili. Two are c^uite typical, agreeing 

 in color with the original description and with Papuan specimens, 

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

 oblicjue 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
