A specimen of this species in the British Museum bears 
the MS. name Ceropales evilis, Bingham, and corresponds 
well to the description, but is without a black band on the 
pronotum, and the wings are hyaline, not yellowish, with the 
costa and radial cell infuscate, as in the type. The median 
segment is smooth throughout, not finely rugulose at the 
apex as in the description of the type. I have not seen a 
typical specimen, but am inclined to regard eawils merely as 
a variety. ‘The front below the antenne and the clypeus are 
very much more elongate than in reversus ; also the sculpture 
of the front and the shape of the third cubital cell are very 
different, as noticed by Diicke.
