 at margins, are highly polished. The abdomen is fully as long as the 

 head and the thorax united, with dorsal segments i and 2 and base of 

 3, rugulose, the remainder of the third and the following segments 

 being smooth and shining ; segments i and 2 have also a longitudinal 

 carina down the center. Wings hyaline, or at most only faintly tinged,
