prosternum "have a transversed striated glossy band of metallic color,
close to the front margin, the rest of its surfaces as well as the lower part
of the sides of the prothorax forming a convexly raised, very minutely and
densely punctate, area of dull red color" while the lateral band on
prothorax runs obliquely from the side of the thorax in front towards the medio-basal
lobe behind.
