 This very distinct and handsome species was one of the com- 

 monest of its genus at Ega, on the trunks of fallen trees in the 

 forest. The shoulders are extremely oblique and scarcely pro- 

 minent, so that the insect has the form of an elongated ellipse 

 truncated at the elytral end. The terminal abdominal segment 

 in the male has both the dorsal and ventral plates truncated ; 

 in the female it is elongated, and the angles of the ventral plate 

 are produced. The anterior male tarsi are widely dilated and 

 fringed*.
