 elevated above the base of the scutellum. Scutellum moderately convex, 

 not very high, broadly rounded; the sides near the base rather strongly, 

 broadly sinuated ; surface finely, distinctly punctured; the punctures

 backward; the adjoining impressions long, rather shallow, and with a 

 single indistinct stria ; the posterior margin but little higher than the
