32 APOGONIA BÜTTIKOFERI. 



The prothorax is strongly transverse, obliquely narrowed 

 in front and subparallel at the base when viewed from 

 above , broadest just behind the middle ; the anterior angles 

 are acute but not prominent, the posterior ones very 

 obtuse; the punctures on the pronotum are fine and rather 

 densely set, equally spread over the whole surface. The 

 scutellum is of a regular triangular shape, and finely and 

 sparsely punctured. 



The elytra are more strongly punctured than the pro- 

 notum , the punctures still larger towards the sides; the 

 lines of punctures on each side of the costae (which in- 

 ter alia are not very distinct) are only a trifle larger than 

 the other punctures but they are closer together; the first 

 costa is broader than the second and provided with finer 

 punctures which are arranged in three irregular rows; 

 the second and third costae have only one row of similar 

 punctures; outward from the third costa there are three 

 rows of punctures similar to those that border the costa, 

 and their interstices, which are as broad as the costa 

 itself, show likewise a row of finer punctures , thus giving 

 a very regular aspect to the punctuation on the lateral 

 portion of the elytra. 



The abdomen is provided along the sides with a sharply 

 raised line; the punctuation on the sides is strong but 

 not dense and hair-bearing , agreeing with that on the 

 pygidium ; on the propygidium the punctuation is strong 

 and more or less confluent. 



The anterior tibiae are bidentate. 



Hab. Borneo: Nanga Raoen (March 1894, Dr. Büttikofer), 

 Mt, Liang Gagang (March 1894, Dr. Hallier) and Poelau 

 on the Sibau River (June 1894, Dr. Büttikofer), one specimen 

 from each of these localities. — Moreover I have speci- 

 mens from Sambas (Dr. Bosscha) , from Sintang (Severin) 

 and from the South Eastern District of Borneo (Bates).
