the labial palpi, the simply emarginate mentum, the long 2nd 
joint of the antennae, and the simple tarsi, — are sufficient cha- 
racters to distinguish our genus from Demetrias (folio 119). 
In the following list the British species are arranged ac- 
cording to their affinities : the divisions that have been pro- 
posed, founded on the presence or absence of the wings, being 
useless, since the same species in some instances have, and in 
others have not, wings.
