in the males, which are also furnished with a small anal tuft. 

 It includes a great number of genera and species, inhabiting 

 the warmer parts of the Old World. They only touch the 

 Palaearctic Region in North China, Japan, and Amurland,

 The African species here figured belongs to one of the 

 more distinct genera.
