flatter ocelligcrous tubercle, and the middle and side stripes 

 of thorax arc pubescent. The si)eeies are usually darker- 

 coloured, and not so large as a rule, and the thorax is not 

 so distinctly striped; but the division of these two genera 

 appears based on rather unsatisfactory characters. Alcimus 

 ponticns is now removed to this genus. 



The genus is confined to the Oriental and South African 

 Regions, with tbe exception of Fhilodicus spectabilis, Loew, 

 from Turkestan, Fhilodicus himacuiatus, Becker, from Persia, 

 and PJiiludicus canescens, Wlk., from Austialia, and the above 

 Alcimus ponticus, from Persia.
