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*.
