The uniform dull brown colour of this species, together with 

 its sturdy build, and the powerful strongly toothed forceps of the 

 male, render it easy to recognize. The details of the dentition 

 of the male forceps vary a good deal ; sometimes there is a pair 

 of stout conical teeth near the base, and sometimes they are fused 

 into one dilated and depressed projectiou, having a strongly 



In the sturdy build, rather thick antennae and strong forceps, 

 this species approaches Gh. morio. 



It is widely distributed throughout the Oriental Eegion. 



F. fascipennis, Haan, from Borneo and Sumatra, appears to be 

 related to it, and is perhaps only a race or variety, but the forceps 

 are weaker, the head is red, and the antenna) have a pale ring.
