species from the preceding. The sides of the uietasternum are 

 closely punctured and more opaque than the rest of the underside. 

 Whether this species is specifically distinct from C. fulvipes is 

 doubtful.

Black ; labrum fulvous ; head with a few punctures ; antenna) 

 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. Scutellam narrowly elongate. Elytra strongly punctate- 

 striate, sixth and seventh rows united near apex, interstices at 

 sides longitudinally convex. Sides of breast with a double row of

Hab. Madura. Type in Coll. H. E. Andrewes. 



Differs from 0. niyripes, Jac. in the distinctly punctured thorax ; 

 from G. andreivesi in the black antennae and the different sculpture 

 of the thorax ; from 0. chalceus in the deep black colour, straight 

 sides of the thorax, and the even size of the elytral punctures 

 which are placed in deep stria3 and are distinct to the apex. 



325. Coenobius 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 

 subcylindrical, sides strongly denexed, median lobe not pointed, 

 slightly produced ; surface strongly but remotely punctured at 

 middle and base, sides nearly impunctate, with a narrow oblique 

 sulcus. Elytra deeply striate, the punctures obsolete except at 

 sides, the interstices strongly longitudinally costate. Sides of

Nab. Andaman Islands (Coll. Brit. Mus.). 



Separated by the entirely fiavous 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. 



320. Coenobius discicollis, sp. n. 



Black : head and sides of thorax reddish -fulvous ; legs fulvous*. 



Head with a few fine punctures ; antennas in the type and only 

 specimen wanting. Thorax strongly transverse, impunctate except 

 the usual row of punctures on posterior margin, disc black, sides
