 venter banded with black and white, basal halves of segments white; tips of seg- 

 ments with pale, rather Icng hairs ; end cf abdomen bristly. 



Wings moderate, hyaline ; peticle of second marginal cell one-fifth as long as

 joint; last two joints somewhat thickened and with tip of long joint hairy; 

 vestiture entirely bronzy black. Antennae plumose; last two joints long and 

 slender, rugose, pilose, black, the others short, whitish, ringed with black at

Genitalia (plate 10, fig. 70) : Side-pieces over twice as long as wide, tips con- 

 ically tapered, a subapical prominence divided into three portions, the outer 

 portion bearing two rods, a leaf -like appendage and two filaments, the other two 

 bearing each a single filament with expanded tip. Clasp-filament narrowed at 

 middle, tip expanded something in the shape of a foot with a row of spines on 

 outer edge, an articulated terminal spine. Harpes with a long, slender inner
