rax in the middle of the base, two tubercles on the posterior edge 

 of the elytra, a large lateral area of the first abdominal segment 

 and the pygidium beneath, light brown. The insect is completely 

 covered with coarse and shallow punctures, in some parts the 

 punctures are shallower, in some they are deeper. 



Head deeply inserted in the prothorax, viewed from the 

 underside flat and closely punctate. There is a lighter triangular 

 area on the interantennal space, and a black longitudinal streak in 

 the middle branching to a certain extent on the interocular space. 

 The e5^es are deeply and triangularly notched on the inner margin. 

 The first joint of the antennae is the thickest and longest, the second 

 small and rounded, the third elongate, the fourth transverse but 

 smaller than the following joints which are all transversely expand- 

 ed. When the antennae are extended forwards the lateral expan- 

 sions of the eight apical joints are on the outer side, in repose

they lie in deep channels, the lateral expansions being on the inner 

 side. Prothorax bisinuate on either side at the base which is as 

 broad as that of the elytra ; broadest at base, narrowed in front, 

 the anterior margin circular, lateral margin oblique and straight. 

 The pronotum is elevated in the middle, the boundary of this ele- 

 vated surface being marked by black. It has four small tubercles 

 surrounded by black, a lighter and larger tubercle behind, chan- 

 nelled in the middle. The rest of the pronotal surface is uneven 

 having elevations and depressions. Scutelhim trapezoidal, about 

 twice as broad as long, the two apical outer angles produced pos- 

 teriorly, the surface rough. Elytra broadest at the base, con- 

 stricted in the middle, coarsely and deeply punctate ; suture serrate 

 throughout; humeral callus raised into a tubercle. On each 

 elytron the basal area along the anterior margin is raised, from the 

 middle of which runs obliquely an indistinct costa on the outer
