Difers from A. rotinidatus in its perfectly oval form, minute sculpture, and very 

 short pubescence ; from the rest in its large size and broad oval form. 



Habitat, Africa. Locality not mentioned. 



In the collection of the British Museum there is one specimen of this very 



distinct and pretty species.

Differs from all others in its very broad form, pale colour, and long pubescence. 

 Habitat, Asia. Found in Borneo by Mr. Bowring. 



This species differs so much from any other Arthrolips that at first I believed it 

 to be generically distinct ; but after a careful examination of its anatomy, I have 

 been unable to discover any character by which it can be distinguished from 

 Arthrolips, except that its maxillary palpi are much broader in proportion to their 

 length than is usual in that genus.
