Species o/Eriocera in the British Museum. 91 



more reddish-tinged, scutellnm and postnotum more 

 yellowish-tinged. Pleurse dark grey, passing to orange 

 above. Abdomen entirely black, mostly shining ; fifth and 

 sixth segments only with narrow velvet-black apical borders 

 (possibly the shining appearance of the basal segments may 

 not be natural). Hijpopygiuin resembling that of E. plumbo- 

 lutea, but the short spines on the bases of the side-pieces are 

 borne on an ear-shaped process ; the outer clasper is thickest 

 neaithe base, where it is finely pubescent ; the inner clasper 

 is narrower ; and the penis, thongb at least as long, is 

 rather differently convoluted. Legs black ; claws with 

 small basal tooth ; empodia short. JVings resembling those 

 of E.plumbolutea, but base and costal region dark ; the large 

 central white spot less square and not quite reaching Cu ; 

 apical white mark long, narrow, and crescent-shaped, 

 extending from before the tip of E2 to the tip of M^ ; Cuja 

 not much beyond middle of discal cell. Halteres black, base 

 of stem pale. 



Length of bod v 11 mm. ; wing 10x3-2 mm.

The specimen was sent by Brunetti as his gravelyi, from 

 which it differs in the orange scutellnm and postnotum, the 

 absence (natural ?) of velvet-black bands on most of the 

 abdominal segments, the shape of the apical wing-spot, and 

 the position of Cu,a. A female of E. gravelyi in the British 

 Museum from Sikkim (/. G. Pilcher) agrees exactly with 

 one sent by Brunetti from the Darjiling district. It seems 

 most probable therefore that Brunetti has confused two 

 distinct species under the name gravelyi.
