MELANDRYINA. 



This tribe, if we include the genus Clinocara, Thorns., 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 antennae ; 

 the British genera may be distinguished as follows : 



I. Tarsul claws simple. 



i. Anterior COXSD separated by the prosternum.
