the middle, and immediately behind this angulation there is 

 a slight but distinct sinuosity ; from this point to the base the 

 sides are gently curved inwards and the margins are thick- 

 ened ; the posterior angles are slightly produced backwards, 

 the produced part obtusely rounded. The elytra are finely 

 coriaceous, distinctly striated, the striee indistinctly punctured, 

 the interstices flat, with rather closely placed, minute, shining 

 dots. The metasternum has an impressed median line, which 

 widens out into a somewhat deep impression posteriorly ; the 

 anterior part is slightly swollen in the middle ; the sloping 

 sides with shining granules. 



This species is very close to G. maurus, Sharp ; but that 

 species is black and has the sides of the thorax more distinctly 

 angular. 



Gymnopleurus assamensis. 



Parum convexus, supra cupreus, subtus cupreo-niger, parum nitidus ; 

 thorace subtiliter coriaceo, punctis parvis sat crebre asperso, ante 

 medium oblique augustato, postice subparallelo, angulis postice 

 rectangularibus, sat obtusis ; elytris tenuiter striatis, striis punctis 

 minutis baud approximatis instructis, interstitiis subtilissime 

 coriaceis et crebre tenuiter nitido-granulosis ; antennis ferrugineo- 

 flavis, basi nigris.

This species is well known in collections under the above 

 name, but does not appear to have been described. It closely 

 resembles G. sinuatus, but is coppery in colour and more 

 finely sculptured, and consequently is less dull ; the sides of 

 the thorax are more distinctly angular. 



Gymnopleurus brahminus. 



Niger, opacus, supra omnino asqualiter subtiliter granulosus ; thorace 

 ante medium oblique angustato, postice perparum angustiore 

 fere parallelo, angulis posticis vix prominulis ; elytris leviter 

 striatis. 



Long. 9 1 lin. 



Hab. China (J. C. Boivrtng, Esq.). 



This species is close to G. sinuatus, but is quite black and 

 dull and differently sculptured. The thorax is obtusely 

 angular at the middle of the sides, scarcely narrowed towards 

 the base, almost parallel, with the posterior angles less pro- 

 minent than in G. sinuatus, but a little more so than in 

 G. melanarius, the angles themselves obliquely rounded off.
