APOQONIA PYGIDIALIS. 29 



the pronotum and a trifle closer together; the first costa 

 is broader than the second and slightly convex , the third 

 not distinct as the punctures on the outer part of the 

 elytra are in lines and the interspaces between these lines , 

 as well as the third costa, bear a regular row of finer 

 punctures; a similar row is present on the second costa 

 which is dilated at its base, while there are two irregular 

 rows on the first costa. 



The punctures on the under surface and legs are hair- 

 bearing; on the sides of the abdomen and on the pygi- 

 dium they are finer than those on the elytra. The pygi- 

 dium is flat or slightly convex , and either impunctate or 

 with a few very fine hair- bearing punctures. 



The anterior tibiae are tridentate, the upper tooth is small. 



Hab. Borneo: Smitau (January 1894, Dr. BiittikoferJ, one 

 specimen; Nanga Raoen (March 1894, Dr. Büttikofer) , one 

 specimen ; and moreover specimens from Sintang (Severin), 

 Sambas (Dr. Bosscha) and the South Eastern District of 

 Borneo (van Nouhuys). 



From the same localities, and moreover from Nanga 

 Pinoeh ^) , I have specimens which perfectly agree with 

 those of A. pygidialis except in the sculpture of the py- 

 gidium, this being strongly though not very densely punc- 

 tured. Not being sure of their identity I have named these 

 specimens A. incerta. 



Apogonia Waterhousei , n. sp. 



Allied to A. fulgida Sharp from Sumatra, of which 

 I have the type-specimens before me , but easily distin- 

 guished from that species by the smaller head, by the 

 shape of the clypeus the lateral margins being conver- 

 gent in straight lines , whereas in fulgida they are strongly 

 rounded which makes the clypeus longer in front of the

 Museum by Mr. W. Albarda.
