Pronotum with the anterior area strongly gibbous, centrally 

 perpendicularly raised, the apex developed into a transvejse 

 curved process on each side, the posterior process as in 

 Anchon, Buckt. 



The type of this genus is the Centrotus hipennis, Walk., 

 for which that writer has given an unusually complete 

 structural description, which may be used for the generic 

 characters. 



Allied to Beninia, Dist., from which it differs by the 

 peculiar structure of the posterior pronotal process, which 

 also separates it from the Australian genus Eutryonia, 

 Goding. From the latter it is at once separated by the 

 different structure of both the anterior and posterior pro- 

 notal processes.
