 mesosternum connected with that of mesepisternum, hind margin of 

 mesepimeron, sordid-white; sternites except apical margins blackish; 

 ventral margins of tergites yellowish; median spot on tergites three 

 and four testaceous. Hypopygidium yellowish, narrowly rounded 

 apically. 



Type locality. — Ramgarh, Kumaon, British India.
