This genus belongs to the " sous-trihu Itliyporides " of M. 

 Laeordaire ; but I am unable to assign it to either of tlie eight 

 " f/roupes" into which he has divided it: the character of the 

 elytra closely embracing the body vs'^ould exclude it from every 

 one except the " Ocladiides," from which it differs essentially in 

 its rostral, anal, and other characters. It would therefore, in 

 M. Laeordaire' s system, form a ^^ groupe" to itself. There are 

 four species in my collection ; two of these are here described, as 

 one of them differs structurally in having an elevated process 

 projected forwards on to the prothorax at the base of each ely- 

 tron ; but all four species are exactly alike' in outline, which, as 

 will be seen by the figure, is rather peculiar.
