COEKOBIU8. 185 



scarcely produced ; surface with a deep oblique transverse groove 

 at sides, disc impunctate, a single row of punctures close to lateral 

 and posterior margins, latter without denticulation. Scute! lutn 

 narrow, linear, longitudinally concave at base. Elytra not broader 

 at base than thorax, shoulders prominent, punctures deep, regular 

 and distinct to apex, interstices at sides longitudinally convex, 

 impunctate. Prosternum broad, its base slightly widened and 

 truncate, surface transversely sulcate anteriorly and posteriorly. 

 Abdomen nearly black. 



Length 2 mm. 



Hob. Burma : Karennee. Type in Genoa Mus. 



Principally distinguished by the strongly grooved thorax. 



319. Ccenobius chalceus, sp. n. 



Black with slight aeneous gloss ; labrum and tarsi beneath 

 obscure fulvous. 



Head strongly and deeply punctured : antenn in the type and 

 only specimen wanting. Thorax strongly convex, sides narrowly 

 margined, feebly rounded ; surface strongly and closely punctured 

 at sides, the punctures elongate and partly confluent, middle of 

 disc more sparingly punctate; median lobe short and triangularly 

 pointed, preceded by a row of punctures which run parallel with 

 the basal margin. Elytra with strongly tuberculate shoulders, 

 surface strongly punctate-striate, the sides with larger punctures 

 and costate interstices. Sides of breast with a double row of 

 punctures, middle irregularly punctured. 



Length 1| mm. 



Hob. Nilgiris (Coll. II . E. Andrewes). 



This species, of which I have seen only a single specimen, is not 

 so deep a black as most of its allies, but has a distinct aeneous 

 gloss; the thorax and elytra are more strongly and closely punctured 

 than in any other Indian species of the genus and the legs are 

 entirely black. 



320. Ccenobius seminigris, sp. n. 



Fulvous ; terminal joints of antenna) piceous ; elytra black. 



Head with eyes that occupy the entire upper and lateral portions ; 

 clypeus pale fulvous, distinctly punctured ; antennae extending to 

 base of thorax, basal five joints fulvous, third and following two 

 joints slender, rest widened, but distinctly longer than broad. 

 Thorax subcylindrical, strongly narrowed in front, basal margin 

 produced at middle into a very short pointed lobe ; surface with a 

 transverse sulcus behind the middle, extending across disc, entirely 

 impunctate, posterior edge lined by a row of punctures. Scutellum 

 lanceolate, black. Elytra about one half longer than thorax, 

 scarcely narrowed behind, apex of each broadly rounded ; surface 

 strongly punctate-striate, each row of punctures commencing with 

 a small deep fovea near basal margin, the latter carinate, interstices
