CCENOBIUS. 183 



pointed or rounded. Scutellum lanceolate. Elytra with strong 

 epipleural lobes, regularly punctate-striate. Prosternutn broader 

 than long. 



The most reliable character for distinguishing this genus is the 

 structure of the eyes, which meet at the top of the head ; the 

 dilated terminal joints of the antennae and the structure of the 

 prosternum are subject to variation, although the former organs 

 are never long and filiform as iti Cryptocephalus proper. 



314. Ccenobius insularis, Weise, Dent. ent. Zeit. 1903, p. 34. 



Black ; antennae and legs flavo-testaceous, last four or five joints 

 of antennae and the intermediate and posterior femora darkened. 



Thorax convex, smooth and shining, with a row of strong punc- 

 tures round lateral and basal margins only. Elytra with inner 

 rows of punctures narrow and moderately strong, outer rows much 

 broader and deeper ; sometimes only the posterior femora dark- 

 ened ; sides of metasternum irregularly punctured in single rows, 

 these are, however, doubled anteriorly and posteriorly ; projection 

 of basal margin of thorax very small and rounded. 



Length 1-5 mm.

315. Ccenobius laevicollis, Jac. (Buchari*) Stett. Ent. Zeit. 1899, 

 p. 265. 



Black ; basal joints of antennae, lower portion of face and legs 

 fulvous. 



Upper portion of head entirely occupied by the eyes, which meet 

 at top ; clypeus fulvous ; labrum piceous ; antennae extending to 

 base of thorax, terminal six joints widened, basal five fulvous. 

 Thorax strongly transverse, sides strongly deflexed, lateral margins 

 nearly si raight," narrowed anteriorly, anterior margin preceded by 

 a narrow groove, posterior margin with a row of deep punctures, 

 surface inipunctate, sides with a narrow oblique groove, the middle 

 lobe on the posterior margins pointed. Scutellum lanceolate. 

 Elytra evenly and strongly punctate-striate, the punctures deep at 

 base, the basal margin strongly transversely carinate, interstices 

 broad and flat at inner disc, lateral two distinctly convex and 

 narrower. 



Length l|-2 mm. 



ffab. Tenasserim : Tavoy ; Sumatra. 



This little species was placed in Bucharis, but wrongly so because 

 of the contiguous eyes. The Suraatran specimens differ in no way 

 from those obtained by Doherty in Tenasserim. The thorax in 

 some specimens is more or less fulvous at sides or base, while the 

 elytra show likewise a slight fulvous tint, probably due to imma- 

 turity of the specimens examined.
