236 OXYRHYNCHUS SUTURALIS. 



between the pits are narrow and eostiform. The anterior 

 border of the prothorax bears an edge of hirge punctures. 

 Scutelluni of an elongate ovate shape, pointed at the apex; 

 its surface unequaL 



The basal margin of the elytra somewhat raised in the 

 middle, and more or less rounded for each of them; the 

 shoulders slightly prominent and rounded , the sides sub- 

 parallel , narrowing gradually towards the apex. The elytra 

 are narrower than in the other species of the genus Oxy- 

 rliynclius and covered with rows of pits similar to those 

 of the prothorax , but becoming gradually more elongate 

 and confluent towards the apex. The transverse inter- 

 stices are raised , confluent , and give to the elytra the ap- 

 pearance of being transversely wrinkled. The longitudinal 

 interstices are alternatively a little more raised than the 

 others, beginning with the interstice between the second 

 and third rows of pits. The first only is evidently so. 



The under surface of the body as well as the femora 

 covered with large and shallow punctures , which are 

 similarly furnished as the pits of the upper surface. The 

 tibiae with indistinct grooves. The pygidium finely rugose. 

 The rostrum provided at its under surface Avith a dense 

 yellow pubescence , which disappears towards the apex. 



A single specimen captured ac Simawoeng , during the 

 Scientific Sumatra-Expedition, in June 1877. 



This species is quite distinct from the other OxyrJiyn- 

 chus , especially by its different coloration , which as far as 

 we know at present is rather unusual in this genus. 



Brussels , January 1880.
