Ceylon Coleoptera, 8fc. 55 



acquires its greatest density on the legs, especially the tibiae 

 and tarsi; Avhilst their uniform presence at the palpi forms 

 almost a generic character. The elytra are exquisitely sculp- 

 tured into about 8 larger costae on either of them and into 2 

 smaller ones between every 2 of these, the furrows thus formed 

 are finely transversely rugose and (with the exception of the 

 central furrow between every 2 larger costae) thinly pubescent.
