 the male with a long tuft of hairs attached close to the proximal end, and reaching well 

 beyond the distal cud of the tibia. 



" This genus is confined almost entirely to Africa and the Malay Archi- 

 pelago, hetijamini alone being found in India, China, and Japan, while the 

 range of anchises extends to Aden." ( Wafson, I. c.)

 Both forms occur in China, together with examples intermediate between 

 the two.
