 rupted white band on the front margins of the segments ; alulae dirty white ; 

 halteres yellow ; wings with a costal spine, and nigrescent along the front border.

C. ^NESCENS, Zett. 

 This species differs from the former (mcerens) by being a little larger, more 

 aeneous in colour, with rather wider frontalia ; by the buccal setse being arranged in a 

 less regular row ; by the cheeks and chin being larger ; by the abdomen being wider 

 (less cylindrical), and quite of a glistening seneous black colour, and by the cell-stalk 

 of the wings being a little shorter. Not very rare.
