 verse, slightly and broadly produced in front ; immediately above

 gin of the eyes (near the termination of the transverse carination) 

 are two suffused circular spots of rufous colour. Thorax elongate ; 

 the anterior angles depressed and very broadly truncate (the trun-

 stinct tooth-like projection) ; the sides subdepressed and marginate ; 

 at the base is a slight transverse depression, above which (near the 

 centre of the disc) are two distinct elevations ; the surface impunctate, 

 flavo -ferrugineous. ScuteMum small, triangular, fuscous. Elytra 

 broad, subparallel, subdepressed, punctate-striate ; the surface is
