large elongate mark on each .side of prothorax in front of tegulse, a triangu- 

 lar spot beneath wings, two large transverse spots on scutellum, band on 

 postscutellum interrupted medially, sometimes two spots on metathorax, 

 and sometimes two small spots on mesothorax posteriorly, lemon-yellow ; 

 clypeus rather broader than long, with a black dot on middle; the apex 

 broadly and rather deeply emarginate ; the lateral angles prominent; eyes
