LOPHOPiN.i:, 317 



Subfamily VIII. LOPHOPIN^. 



Lophopida, Stal, Hem. Afr. iv, p. 130 (1866). 

 Lophopiaa, Atkins. J. A. S. Beng. Iv, p. 42 (1886). 

 Lophopidse, Melich. Horn. Faun. Ceylon, p. II (1903). 



Head narrower than pronofcum ; rostrum short, stout, with 

 the apical joint short ; pronotum usually truncate at base, as 

 described by Stal, but sometimes coucavely sinuate or angularly 

 eraarginate, carinate or somewhat tubercular on disk ; basal joint 

 of posterior tarsi robust and moderately short. 



I take the most distinguishing character of this subfamily to be 

 the robust or incrassate basal joint of the posterior tarsi, and it 

 apparently contains two sections, denoted by the more or less 

 dilated anterior tibiae, and the reverse. Stal's chai'acters are 

 rather too restrictive.
