Prostcrnum deeply ineurved, the obtuse outer angles of 

 the eninrgination representing ocular lobes. Anterior cox(E 

 prom incut, globose, contiguous, and situated near the hind 

 margin; the intermediate moderately, the posterior widely 

 separated. Metasternuni short, plane or concave. Abdomen 

 narrowed behind, second segnuait as long as the metasternum, 

 the first much longer; there is a curvate impression between

 female there are series of minute nodules.
