Linden describes a ¢ which he supposes to belong to this

Entirely black: head punctured, with a longitudinal impres-

wings very slightly coloured and having an iridescent reflection, 
the nervures piceous, and the third submarginal cell much larger

very short cilia upon the anterior tarsi, and the intermediate and

with a silvery down; the metathorax and coxe have a sericeous 
reflection ; the apex of the anterior tibize are fulvous and their 
tarsi piceous ; the sixth ventral seoment is emarginate.
