VI. COLEOPTERA. 

 By C. O. Waterhouse. 



Several specimens of Coleoptera were collected ; but as the 

 majority belong to widely spread genera the species of whicii are 

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

 tion of the tuo following new species. 



Chrysodema simplex, sp. n. 



Viridi-aurata ; tJiorace cyaneo-viridi, linea mediana l<Bvi, fossa 

 laterali rof-undata ciiprea confertim rugulosa ; elytris costatis, 

 casta marginali viridi ; femoribus (ibilsque cupreis. 



Long. 12| lin. 



Resembles C. auro^ilagiata, 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 auropJagiata. The lateral rugose coppery 

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

 plagiuta, 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 

 costae are very slightly raised, the 2nd, 4th, and 6tli 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
