 the top and the sides of the raised central part smooth, the rest with large 

 scattered punctures. Pro-mesonotum and scutellum closely, strongly rugoselv 

 punctured, the punctures on the mesonotum running into reticulations. Meta-

 curved striated band down the hollowed centre. Metapleurae strongly, 

 closely punctured.

 angular spot on the apical three-fourths of the mesonotum, the narrowed end 

 at the base, a line down the centre of the scutellum, a broad irregular line on 

 the sides of the abdominal petiole, the apex of 2nd and the greater part of the 

 following segments, a line on the outer sides of the hind coxae on the lower
