more resemblance to the North-American, than to the Eastern 
representatives of the genus. 
The British Museum possesses yet two species, which agree 
with Anisocentropus in the neuration, tibial spurs, and general 
appearance, but differ somewhat in the maxillary palpi; these 
have the terminal joint strongly fringed with long hairs, and 
several of the joints have the appearance of being somewhat 
dilated; but the differences seem scarcely sufficient to warrant 
their generic separation. The single example of each species is 
not in sufficiently good condition to enable me to draw up a satis- 
factory description. They are from the Philippine Islands and 
New Guinea respectively.
