central segments glabrous ; finely pilose and deep black, the apical 

 half of the two basal segments and the third, except in centre of 

 its base, deep red ; hypopygium apically truncate, rufescent and 

 covering the base of the eoncolorotis terebra. Legs short and 

 stout, black, with the anterior tarsi, the front and base of inter 

 mediate tibiae and the front femora, except at their base, testaceous ; 

 hind tibiae broadly rufo-testaceous centrally ; pulvilli elongate, 

 claws simple. Wings testaceous-hyaline, with the costa, stigma, 

 radix, and tegula3 testaceous ; nervures blackish. 



Length 11-12 milliin. 



ASSAM : Shillong, 6000 ft., iv. and ix. 03 (Rowland Turner). 



Type in the British Museum. 



The abdomen varies both in the length of the petiolar carinae, 

 which in the type are simply basal, but in the larger specimen 

 extend beyond the centre, and in coloration, since in the latter 

 both base and apex of the second segment, merely the apex of the 

 first, the whole of the third, and the sides of the fourth laterally, 

 are red.

 with the latter strongly carinate between the scrobes ; face strongly 

 and evenly punctate and with white hairs throughout, not im- 

 pressed, nor discrete from the small and apically truncate 

 clypeus ; mandibles and palpi flavescent, with apices of former

 notauli ; mesopleurse nitidulous and distinctly punctate; mela- 

 thorax basally and laterally black and very finely punctate ; lateral 

 carinae distinct both above and below the strongly elongate spiracles ; 

 basal area minute and incomplete ; petiolar area AA r antiug, apically 

 longitudinally tricarinate and subproduced on either side of the
