VI. COLEOPTERA. 

 By C. O. Waterhouse. 



Several specimens of Coleoptera were collected ; but as the 

 majority belong to widely spread genera the species of which are 

 most difficult of discrimination, I must limit myself to the descrip- 

 tion of the two following new species. 



Chrysodema simplex, sp. n. 



Viridi-aurata ; thorace cyaneo-viridi, linea mediana leevi, fossa 

 laterali rotundata cuprea confertim rugidosa ; elytris costaiis, 

 casta marginali viridi ; femoribus tibiisque cupreis. 



Long. 12| lin. 



Resembles C. auroplagiata, Deyr. (having the thoracic impressions 

 nearly round and very sharply defined), but at once distinguished 

 by the elytra having no lateral impression. The thorax is of a dark 

 blue-green, with golden-green punctures, and a line of green on each 

 side of the smooth median line. The punctures on the disk are not 

 so numerous as in C. auroplagiata. The lateral rugose coppery 

 impressions are round, relatively rather smaller than in C. auro- 

 plagiata, with the lateral margin distinctly elevated. The elytra 

 appear golden green or slightly coppery according to the position of 

 the light ; there is a distinct green tint below the scutellum. The 

 costse are very slightly raised, the 2nd, 4th, and 6th more distinct 

 posteriorly ; the sublateral costa is smooth and bright green, the 

 margin of the elytra (beyond the costa) golden. Prothoracic epi- 

 sterna somewhat golden, tinted with coppery and green in parts ; the
