Posterior tibia though with moderately long bristles, these are invariably and visibly shorter than tibial width at this place.

Anal vein otherwise construed. 3 (4) Wings colourless, c-bristles stronger. Third longitudinal vein reaching costa nearer to apex—in 2/3 of the section between upper apex of discoidal cell and apex of wing —its termination subtending an acute angle with costa. Sixth longitudinal vein (anal vein) bifurcating: its upper branch (towards fifth longitudinal vein) thick and very short, its lower branch thin, bending arcuately towards alar apex, nearly reaching margin of wing pilosa DTJDA 4 (3) Wings greyish, c-bristles weaker. Third longitudinal vein reaching costa further from apex of wing —in 1/2 of section between upper apex of discoidal cell and apex of wing —terminating almost perpendicularly in it. Sixth longitudinal vein rudimentary, hardly discernible, consisting of two disunited sections kertészi DUDA Finally, I should like to express my thanks to Dr. H.
