Seirotrana vertebralis, n.sp. 



Oval-depressed, bronze, subnitid, tarsi red, legs, antennae and

Head rugosely punctate on front, more finely punctate on 

 epistomal ridge, the latter only slightly raised above frontal

 Sides very gradually rounded, sinuous near base. Hind angles 

 rectangular. Front and base sinuate, the latter having scutellar
