 From the remarkable compressed antennae I am inclined to con- 

 sider this insect, which was received from the island of Madagascar, 

 as the type of a distinct genus. The following characters may be 

 deemed sufficient to mark its peculiarities, which are chiefly taken 

 from the antennae, and hence it has been named 



Piezophyllus* . 

 Caput rotundatum, antennis valde compressis, undecim articulatis, ar- 

 ticulo 1°^° crasso, 2'^° brevi, octo sequentibus gradatim decres- 

 centibus, ultimo apice acuto. Thorax angulis anticis rotundatis, 

 posticis acutis. Elytra subacuminata e sutura dehiscentia late- 

 ribus medio subsinuatis. Pedes robusti, tibiis subincurvis. 

 Other peculiarities might be mentioned ; but as it is well-figured, 

 however, its other characters may easily be distinguished.
