C. iENESCENS, Zett. 

 This species differs from the former {mcBrens) by being a little larger, more 

 feneous in colour, with rather wider frontalia ; by the buccal setae 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 aeneous black colour, and by the cell-stalk 

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