I have never met with this species myself. The following is 

 from Mr. O. Harger's description. 



Body broad, oval, usually oblique and with the sides of un- 

 equal length; dorsal surface moderately convex. Head small, 

 rounded in front, trilobed behind, the middle lobe much the 

 largest, the two lateral lobes extending beyond the eyes which 

 are inconspicuous, small, and broadly separated.
