sufficiently indicate, and it is uiinecessary to describe it at greater 

 lengtli. I will however take this oi)portniiity of remarking- that I 

 have some doubt whether the species described as G. melanarius by 

 Harold (Col. Heft. I. p. 76) be the species usually staiiding in col- 

 lections witb tbo nanie G. melanarius Mannerheim. Harold says 1. c. 

 that the species has „Patria Sumatra" ; in his Catalogue of Coleoptera 

 however he gives Java as the locality of the species; all the speci- 

 mens I have seen come from China, and Mr. G. Lewis has given me 

 an individaal which he captiired in Northern China, so that if Ha- 

 rolds species be really from Sumatra and conspecific with the Chinese 

 individuals, the species must have a rather wide distribution.

Borneo: Sarawak (Wallace !). 



Clypeus bidentato in the middle, not at all sinnato outsido the 

 middle teeth. Thorax smooth. opaquc, with a silky appearance, its 

 sculpture very little marked, consisting of sparing* and extromely fine 

 punctures ; its sides have in the middle a remarkably distinct angular 

 projection. Elytra flnely but distinctly striatod , with very obscuro 

 sculpture. Pygidium silky and opaque. The threo teeth at the apex 

 of the front tibiae very close to ono another. 



This species is closely allied to the Chinese G. Melanarius, but 

 is more opaque and readily distinguished by the angulated sides of 

 the thorax. The two si)ecimcns from which my description is mado 

 are male and female; the spur at the extremity of the front tibiao in 

 the S being broad, and a little sinuated at the extremity, so that the
