MELANDRYINA. 
This tribe, if we include the genus Clinocara, Thoms., which certainly 
seems distinct, contains twenty-one European genera, of which twelve 
are found in Britain; another genus, Serropalpus, has been included by 
some authors, but not, apparently, on sufficient authority to render it 
entitled at present to be considered indigenous ; the characters before 
given for the family will serve to distinguish the tribe, as it contains all 
the European genera except Tetratoma, which, as above stated, may be 
known by the very abrupt and strong 4-jointed club of the antenne ; 
the British genera may be distinguished as follows :— 
I. Tarsal claws simple. 
i. Anterior coxze separated by the prosternum.
