ATR[CHOPS, 117 



Waek ; tlie Fore femora (except base and tip), the apical half of 

 the uiiddle femora, the middle tibiaj wholly, and the hind femora 

 are yellow, but the latter bear a broad deep black band, occupying 

 about the middle half of their length. The wing has a large, very 

 distinct, blackish-brown stigma, whilst the cross-band on the wing 

 is much darker. The abdomen is differently coloured, closely 

 resembling that of calopa, except that the posterior half of the 

 4-th and 5th segments is occupied by a whitish band, which is 

 invisible from certain points of view ; the basal half of the 6th, 

 and the whole of the Gth, segment is black. 



jProm calopa the broad band on the hind femora easily separates 

 it, this character being consistent in the ten specimens examined. 

 The wing-marks also distinguish it, owing to the prominent 

 stigma and the much more distinct apical part. 



Length, 8| mm. 



Described from ten S c? in excellent condition taken by Dr. 

 Annandale, 10. iv. 1909, on Paresnath Hill, A¥est Bengal, 20(30 ft., 

 on rocks at the edge of a small jungle-stream, where it was 

 present in large numbers ; Bojiaghat, 12. vi. 1915. 



This is evidently a good species, the ten specimens agreeing 

 exactly in all particulars, whilst the three examples of my calopa 

 are also consistent ; limbata of Osteu-Sacken, however, according 

 to him, appears to be variable. The present species is best 

 described as possessing the abdomen of calopa with the wing of 

 limbata, with the addition of an all-black thoi'ax and a large black 

 •stigma.
