Tjongicornia Malayana. 669 



subtilissime punctatum, opacum, segmentis quatuor 

 basalibus fascia leevi marginatis. Corpus glabrum. 



The antennee and legs are shorter, and the legs less 

 robust, in the female ; and in B. Manillce, the punctuation 

 on the abdomen is much less dense, and the deadness 

 of its surface therefore less pronounced, in that sex. Of 

 the following species, I only know the female, JR. sutur^ 

 alis, the type, is unknown in our English collections. 



Wiaphipodus Wallacii. 



R. niger, nitidus; elytris pallidioribus, nitidissimis j 



prothorace utrinque basi leviter incurvato. 

 Ha h . — Sarawak . 



Black, shining, elytra with a brownish tint, and very 

 glossy ', head with a well-marked triangular excavation 

 between the eyes, the vertex finely granulate ; prothorax 

 short, very transverse, the posterior spine prolonged, 

 the portion of the side behind it very slightly incurved, 

 the disc with two large very glossy median callosities, 

 the rest finely and closely punctured, with the intervals 

 granuliform; scutellum oblong, slightly pointed behind, 

 finely punctured; elytra very convex, the punctures 

 minute, shallow, and much dispersed, except at the base, 

 where they are somewhat confluent, throwing the in- 

 tervals into slight corrugations; body beneath dark 

 reddish-brown, minutely and very closely punctured; 

 legs brownish-black, the outer and inner edges of all the 

 tibise denticulate, but less so on the four posterior ; an- 

 tennse brownish-black, the scape rather thickly punc- 

 tured, except at the apex, where it is nearly impunctate. 



Length 17 lines. 



This is a more convex species than B. Manillce, with a 

 shorter and broader prothorax, the spine nearer the 

 base, the scutellum distinctly punctured, &c. The den- 

 ticulations on the four posterior tibiae are probably 

 liable to disappear, as they sometimes do in B. Manillce,
