ERIOCERA. 545 



the 6th, and just proximad of the 2nd suhmarginal and di»eal 

 cells. Venation normal ; four posterior cells ; posterior cross-vein 

 beyond the middle of the discal cell. Halteres black. 



Length 12 millim. 



Described from one male from Kurseong, 9. ix. 09 (Annandale).. 



Type in the Indian Museum. 



A distinct and rather handsome species considerably i-esembling 

 my E. plumUcincta owing to the silvery leaden abdominal bands, the^ 

 yellow legs and the size. It is, however, at once distinguished by 

 the dark genitalia, and more readily still by the presence of only 

 four posterior cells.

'■'■Head grey. Proboscis brownish; palpi blackish; 1st joint 

 narrowed, the remainder moderately thickened. Antennae : 1st 

 joint rather long, brownish, the 2nd cyathiform (the remainder 

 missing). Thorax brownish grey, with three black almost 

 contiguous stripes ; a small round black spot in front of these 

 stripes. Abdomen : the first three segments yello\\ish orange, 

 the rest black ; ovipositor yellowish, elongate. Legs : femora 

 yellowish, with ash-grey dusting (remainder missing)'. Halteres 

 brown. Wings : the two mai'ginnl cells di\ided by a cross-vein ; 

 the two suhmarginal [cells] divided by a longitudinal vein ; the 

 outer one shorter than the inner one ; the 2nd posterior cell 

 rather small, with a long petiole ; base of wing, the front margin,, 

 and a wide transverse band behind the discal cell, yellow ; the 

 remainder brown.

Van der Wulp, in the Mid-Sumatra Expedition Eesults, notes 

 this species, recording two females from Koetoer, Sumatra, taken 

 in June. His specimens are 14 to 17 millim. in length, Macquart's 

 example being only 10 millim. However, this would not preclude the 

 two forms being identical. Van der Wulp's coloured plate of the 

 wing shows the species to be allied in this respect to E. ncpalensis, 

 Westw., the brown of the wing being lighter in colour.* The 

 venation is very similar, except that the anterior and posterior 

 cross-veins are not so nearly in a line, and both lie distinctly before 

 the fork of the 2ud longitudinal vein. There are, moreover, five 

 posterior cells. The transverse stripe is twice as broad, is broader 

 on the hind margin, and is yellow and not ^^-hite. The centres of 

 most of the cells are a little paler, a character I have not seen in 

 E. nepalensis. Macquart's reference to the division of the two 

 marginal and two submai-ginal cells is not clear. The subcostal 



Pos8ibly due to the fading of the colours, which occurs in some 



species.
