PACHYTERIA BORNEOENSIS. 249 



punctures confluent in a longitudinal direction ; the cly- 

 peus rather distantly punctured ; the labrum large , deeply 

 emarginate anteriorly, finely and sparingly punctured. The 

 antennae slender, the scape short, rather strongly but 

 not densely punctured , sharply spined at the top and 

 provided , inwardly from the spine , with an infuscate 

 round spot; the 3rd joint not quite so long as the 

 4th and 5th together, the 4th — 6th equal in length to 

 one another, the remainder slightly decreasing in length, 

 the apical joint, however, decidedly longer than the pen- 

 ultimate one. 



The prothorax broad , its sides rounded anteriorly and 

 strongly angulated behind the middle ; the angle termina- 

 ting in an acute point ; the raised disk finely rugose , 

 densely covered with a velvety black pubescence, with a 

 smooth space at the middle of the base , the upper sur- 

 face of the lateral angles smooth , almost impunctate ; the 

 contracted anterior- and basal portion irregularly wrinkled 

 and punctate. The under surface of the prothorax is very 

 densely and evenly punctured , forming a dull lustreless 

 surface which is also to be seen from above between the 

 front margin and the tip of the lateral angles; the con- 

 tracted front portion is transversely wrinkled, the inter- 

 coxal part sparsely punctured. The scutellum triangular, 

 slightly longer than broad at the base, densely covered 

 with a black pubescence. 



The elytra slightly narrowing towards the apices which 

 are emarginate; they are densely covered with punctures 

 which decrease in size towards the end , and show each 

 three slightly raised smoother costae. 



The metasternum and abdomen have large punctures 

 irregularly scattered over the surface, and along the middle 

 of the former a fine raised line is present. The 5th ven- 

 tral segment is broadly and deeply emarginate behind ; 

 the 6th segment, which is narrower and in the middle 

 impunctate, faintly emarginate. The femora are strongly 

 punctured, the tibiae much more finely so. The intercoxal
