Type: Holotype, male, USNM 64486, Ulu Gombak, Selangor, 

 Malaya, Dec. 25, 1947, W. H. Lange. 



This species is very close to P. bipartita in coloration, the differences 

 being mainly structural. The abdomen is relatively long and slender 

 and the head is relatively short (flattened), with a large triangular 

 polished area on the posterior margin of the eye. The head charac- 

 ters are that of Pseudophysocephala, and Krober did include one 

 species with an elongated (instead of short) abdomen. However, the 

 new species Physocephala melana is an intergrade, and there are 

 species with a rounded head but large triangular eye area; so that at 

 present I do not believe that Pseudophysocephala can be maintained.

Krober incorrectly describes the third antennal segment as being 

 about as long as the second. However, his illustrations show the
