flatter ocelligerons tubercle, and the middle and side strijjes 

 of thorax are pubescent. The species 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 

 ponticus is now removed to this genus. 



The genus is confined to the Oriental and South African 

 Eegions, with the exception of Fhilod/cns spectabilis, Loew, 

 from Turkestan, Philodicus bimaculatus, Becker, from Persia, 

 and Philodicus cimescens, Wlk., from Australia, and the above 

 Alcimus ponticus, from Persia.
