species from the preceding. The sides of the metasternum are 
closely punctured and more opaque than the rest of the underside. 
Whether this species is specifically distinct from G. fulvipes is 
doubtful.

Black ; labrum fulvous ; head with a few punctures ; antennae 
entirely black, terminal six joints widened. Thorax very short, 
lateral margins straight, basal margin acutely pointed at middle, 
preceded by a row of deep punctures ; surface somewhat closely 
and strongly punctured at sides, middle very finely and sparingly 
punctate. Scutellum narrowly elongate. Elytra strongly punctate-

Hah. Madura. Type in Coll. H. E. Andrewes. 
Differs from C. nig rip es , Jac. in the distinctly punctured thorax ; 
from C. anclrewesi in the black antennae and the different sculpture 
of the thorax ; from C. chcdceus in the deep black colour, straight 
sides of the thorax, and the even size of the elytral punctures 
which are placed in deep striae and are distinct to the apex. 
325. Ccenobius andamanensis, sp. n. 
Head, basal joints of antennae and legs flavous ; thorax, elytra 
and body beneath black. 
Upper portion of head entirely occupied by the eyes; clypeus 
and labrum flavous, strongly punctured; basal five joints of antennae 
flavous, rest black, thickened, extending to base of thorax. Thorax 
subcylinclrical, sides strongly deflexed, median lobe not pointed, 
slightly produced ; surface strongly but remotely punctured at 
middle and base, sides nearly im punctate, with a narrow oblique 
sulcus. Elytra deeply striate, the punctures obsolete except at

Hah. Andaman Islands (Coll. Brit. Mus.). 
Separated by the entirely flavous lower portion of head and 
its strong puncturation, costate and striate elytra, and the 
peculiar shape of the shoulders that are raised into a subquadrate 
tubercle. 
32G. Ccenobius discicollis, sp. n. 
Black : head and sides of thorax reddish- fulvous ; legs fulvous. 
Head with a few fine punctures ; antennae in the type and only 
specimen wanting. Thorax strongly transverse, impunctate except 
the usual row of punctures on posterior margin, disc black, sides
