Ahdoiaen. — Dorsum clove-brown or dark brown, first segment, 

 second segment except hind border and an ill-defined area on

 hind tibiae with a more or less conspicuous (sometimes very 

 conspicuous) dark brown ring round middle, front tibiae also 

 often with a more or less distinct trace of a corresponding mark, 

 tips of hind tibiae with a faint brown blotch on outer side ; tips
