Cephahplatys darwini, sp. n.

 coarsely brownly punctate ; antenna? with the first, second, 

 and third joints stramineous, fourth and fifth ochraceous, 

 excluding first, the joints are subequal in length, first

 twice as broad as long, the lateral margins sinuate, anteriorly 

 ampliate and strongly dentate, the anterior angles produced 

 to beyond the middle of the eyes, lateral angles shortly 

 angularly produced, somewhat thickly coarsely punctate ; 

 scutellum a little more finely punctate, a blackish foveate

Allied to C. fasciatus, Dist., but differing in the less 

 produced anterior pronotal angles, which in C. fasciatus 

 considerably pass the anterior margins of the eyes, the long 

 distinct spine in front of eyes, &c. 



Cephaloplatys dementi, sp. n. 



Dull ochraceous, somewhat thickly darkly punctate ; head 

 sparingly, coarsely punctate, lateral lobes longer than the

 reflexed, rounded anteriorly, sinuate posteriorly, only ob- 

 tusely angulate in front of eyes; antennae with the first,
