Head impimctate, obscure tìavous or testaceous, frontal tuber- 

 cles narrowly transverse, clypeus narrow, triangular, antennae 

 extending to the apex of the elytra, ol)scure fulvous or fuscous, 

 basal joint elongate, second one very small, the following joints 

 as long as the first one, thorax subquadrate , one half broader 

 than long, the sides straight at the base, rather suddenly rounded 

 before the middle, anterior angles tuberculiform, the disc impunc- 

 tate, with two large, nearly contiguous foveae, obscure flavous, 

 scutellum triangular, piceous, elytra slightly depressed below 

 the base, each with about eight or nine longitudinal, not highly 

 raised costae, the interstices finely impressed with transversely 

 shaped punctures, dark metallic green, the disc pale oljscure 

 tiavous, underside and legs flavous, tibiae and tarsi more or less 

 fuscous, the tibiae unarmed, the first joint of the posterior tarsi 

 longer than the following joints together, anterior coxal cavities 

 closed ; the penis short and rather broad , its apex broadly 

 rounded, but slightly pointed. 



Hab. Si-Rambé. 



Whether this species is really distinct from P. nmltkostahi is 

 somewhat doubtful, since structural differences seem to be ab- 

 sent, it is however much larger in size, the elytra have the disc 

 pale flavous with but a slight metallic tint and their punctuation 

 is finer, in one specimen the metallic green is replaced by dark 

 purplish. Of both species, two specimens were obtained. 



lo7. Platyxatitha multicoslata, n. sp. — Elongate, testaceous, 

 thorax subquadrate, ])ifbveolate, impunctate, elytra metallic blue, 

 closely longitudinally costate, the interstices strongly punctured. 



Vm: The antennae, tibiae and tarsi obscure fuscous.

Head rather broad, impunctate, the frontal elevations narrowly 

 transverse, clypeus in shape of a highly raised triangular ridge, 

 the central portion extending upwards between the antennae, 

 its anterior margin perfectly straight, labrum broad, flavous, 

 palpi robust, of the same colour, antennae long and slender,
