248 Mr. F. P. Pascoe's Descriptions of New Genera 



diminishing; scutellum transverse; thorax unarmed, the sides 

 nearly parallel, and about equal in length and breadth ; elytra 

 convex, rather broader behind, and sloped towards the apex; 

 legs very short, mesotibiaa toothed. 



This genus must, I think, be referred to the vicinity of 

 Praonetha. 



Ropica piperata. 



R. grisea, punctata ; elytris nigro-irroratis, maculis parvis albis 

 conspersis ; antennis pedibusque fuscis. Borneo. 



Brownish grey, thickly punctured above ; elytra with numerous 

 black points, and a few small patches, among which, principally at 

 the suture and apex, are a few small white spots ; legs and an- 

 tennae dark brown. 



Length 3 lines. 



Ropica posticalis. (PI. XXVI. fig. 4.) 



R. fusca ; elytris striato-punctatis, macula magna apicali 

 obscure grisea. Hong Kong. 



Dark brown ; head and prothorax thickly punctured, the latter 

 vpith a longitudinal greyish spot on each side at the base ; elytra 

 punctate-striate, an obscure irregular greyish patch at the 

 shoulder, and another larger, but more clearly defined, covering 

 the sloping portion of the elytra. 



Synelasma. 



Head narrower than the thorax ; the antennae distant, short, 

 the first four joints twice the length of the rest together, these last 

 furnished beneath with a row of thickly set hairs ; eyes small, 

 deeply emarginate ; thorax transverse, wider behind, uneven, 

 witii a tubercle on each side anteriorly ; elytra convex, broader 

 than the thorax, the sides parallel, apex rounded ; legs stout. 



This curious genus ought, I think, to be referred to the neigh- 

 bourhood of Praonetha; it is very likely that the comb-like ap- 

 pendages of the antennae are merely sexual. 



Synelasma bufo. (PI. XXVI. fig. 1.) 



S. fusca, rugosa, griseo-lanuginosa ; elytris tuberculatis, basi 

 ferrugineis, lateribus ante medium plaga magnd ochraceA 

 ornata ; antennis annulatis. Borneo. 



Brown, with a grey woolly pubescence, which is very sparse, 

 except on the elytra ; head rounded above, broad and flat in front ;
