punctured, rugose-strigose on the sides. Elytra obsoletely de- 

 pressed below the basilar space, coarsely punctured, the punctures 

 irregularly arranged in double rows, which become single on the 

 outer border and near the apex ; interspaces strongly thickened, 

 very irregularly reticulate; on the hinder disk they form several 

 strongly-thickened but ill-defined longitudinal costse. Thighs 

 simple.

Long. 2 — 2^1in. 



Hab. Sumatra. 



Head coarsely but not very closely punctured, front impressed 

 with a deep and broad but ill-defined longitudinal groove ; epi- 

 stome scarcely broader than long, campanuliform, apical border 

 obsolete, middle of anterior border concave-emarginate, surface 

 coarsely and somewhat closely punctured ; supra-orbital groove 

 deeply impressed, its lower end extending along the upper border 

 of the encarpss to the apex of the epistome, nearly joining its 

 fellow of the opposite side ; antennae slender, filiform, their basal 

 half fulvous ; labrum obscure fulvous. Thorax considerably more 

 tlian twice as broad as long, the sides straight and parallel be- 

 hind the middle, rounded and converging anteriorly ; above convex, 

 sides obliquely deflexed in front, anterior and posterior angles 

 acute ; surface coarsely and rather closely punctured, the inter- 

 spaces very finely punctured, forming on the sides irregularly 

 reticulated longitudinal strigae. Elytra convex, not depressed, 

 below the basilar space, rather finely ])unctured on the inner 

 disk, the punctures on the basal half irregularly arranged in 

 double rows, which on the hinder portion become single and 

 costate ; on the outer disk the punctures are much more strongly 

 impressed and less regular ; the interspaces are very strongly 

 thickened, on the anterior portion they are subtuberculate, and 

 form very irregular reticulations ; on the hinder portion they are
