black upright forked scales ; antennae deep brown, with narrow 
pale bands, basal joint and base of the second joint bright deep 
reddish-brown ; clypeus black; proboscis covered with black 
scales, with a narrow median white band and a pale apex ; paipi 
rather long, pale brown, covered with black scales and a snow- 
white apex. 
Thorax deep, rich brown, covered with scattered jet black 
narrow scales and with numerous black bristles; scutellum

the scales clothing the abdomen rather large ; the lateral bristles 
moderately long, all very thin; on the second to fifth segments 
Ahere are rather long basal grey lateral spots, which become

and mid metatarsi with a basal white spot (not a band), hind 
metatarsi with a pure white band ; first two tarsi in the fore 
legs with a basal white spot almost forming a band ; traces of

brown Taeniorhynchus scales; with oblique, apices, surface of 
wings with curved bristles ; first sub-marginal cell longer and 
slightly narrower than the second posterior cell, its base very 
little nearer the base of the wing, its stem short, less than 
one-fourth the length of the cell; stem of the second posterior 
not quite half the length of the cell; posterior cross-vein not 
quite twice its own length distant from the mid cross-vein.
