Male. " Broader than any other species of the genus. Face, palpi, 

 and antenna? fuscous. Face shining. Occiput opaque fuscous, with grey 

 bloom. Antennae clothed only with fine pubescence (not feathered), 

 scarcely longer than the breadth of the head ; first joint globose, blackish, 

 with a white apical edge; second obconical, longer than the third, 

 yellowish at the base ; following joints oblong ; the next a little more 

 slender, ovate ; the last three ovate, twice as long and broad as those 

 which precede. Pronotum dull ferruginous, with white gloss. Thorax 

 dark brown, opaque, with hoary bloom. Mesonotum with three broad 

 rust-brown bands, confluent on the back, leaving a patch at each an- 

 terior angle, and a line in front (dividing the middle band) of the 

 lighter grey ground-colour. Wings naked, whitish-hyaline; anterior 

 veins pale yellowish, the rest colourless ; two cubital areolets, second 

 about twice as long as the first ; second branch of prsebrachial vein 

 arising before the transverse veinlet. Halteres creamy; base tawny. 

 Abdomen glossy, pitchy ; anterior segments somewhat diaphanous, with 

 the base darker and forming a sinuated transverse band ; hind edge of 

 posterior segments creamy-white. Hypopygium blackish, much nar- 

 rower than the abdomen ; the joints of nearly equal length ; first joint 

 much thicker, conical; second slightly curved, linear, not acute, be- 

 tween them a bilobed process exceeding the tip of the ventral plate. 

 Legs piceous; femora with some minute spines towards the tips beneath; 

 fore pair thickest ; hind tibia? very faintly ciliated ; basal joints of the

" In my descriptions of Ceratopogon, the first externo-median
