Genus. Stethaspis, Hope. 

 Type of the Genus. Melolontha sutuiialis, Fab. 



Caput clypeo integro reflexo. 



Antennce caule quinque-articulato clavaque pen- 

 taphylla. 



Palpi maxillares articulo ultimo longissimo sub- 

 truncato. 



Corpus fere oblongo-ovatum elytris a basi thoracis 

 ad apieem magnitudine increscentibus. 



Thorax postice obtuse angulatus. 



Pectus sterno porrecto acuto armatum, et pilosum.

This Fabrician species differing in its form from 

 any group that I am acquainted with, I have 

 thought proper to consider as the type of a new 

 genus. A second species will be found in my col- 

 lection from the same country as the type, viz. New 

 Holland.
