gladly liave treated them as bot oiie species, but I havo not been 

 able to peivsuado inyself that such is the case, especially oii rccollec- 

 ting' hovv extremely similar to itiie another aro our twd European 

 öpocies G. mopsus and cantharus. That these Eastern iiisects may 

 also be extremely closely allied but truly distinct species seems to me 

 very probable, though sucli cannot be considercd to be certainly the 

 case, tili it has been tested by the exaniination uf an abundant supply 

 of specimens 



Gymnoplcurus f^parsus (n. sp.): Cwprms, antmnis artiado primo 

 ficeo, clava fusca, artimlis intermcdns obscure rufis ; prothorace sericeo- 

 opaco, ferc impunctato, lateribus medio angulatis, angulis postkis ohh(sis; 

 elytris subtiliter striatis, sat er ehre fortiter punctatis; pedibus niffris,

Borneo. 



Clypeus with two distinct teeth in front. Thorax broad^in the 

 middle and angulated at the sides , its hinder angles obtuse and not 

 at all produced, its surface is opaque and silky, almost without sculp- 

 ture. Elytra opaque, finely striatod, the striae formed by punctures, 

 the surface coriaceous and sprinlded besides witli distinct, rather large 

 punctures. Pygidium very opaque. Front portion of metasternum 

 closely and distinctly punctured. Under surface of feinora strongly 

 punctured. 



I have Seen but a single specinien of this species; the punctua- 

 tion of the elytra is different froni any other species of the genas I 

 . have seen.

Laos (Mouhot!). 



Allied to G. sinuatus, but of shortei form, and very remarlcable 

 by the much produced hinder angles of the thorax. Clypeus biden- 

 tato in front. Thorax with the sides rounded in the middle, its sur- 

 face very metallic. Elytra fliiely but distinctly striated, opaque, 

 coriaceous and witli the littlo raised poiuts much less developed than 

 in G. sinuatus. Legs and under surface oljscurely black.
