 the base between the 3 rd aud 4 tn striae ') and the apical 

 half of the elytra black, the latter with a slight tinge of 

 greenish bronze (the black invades the fulvous colour on 

 the middle of each elytron in a strongly curved irregular

 succeeding joints black ; the legs black with the basal half 

 of the femora and a more or less distinct ring around the 

 tibiae (broadest on the anterior pair) fulvous.
