 down to a low apex, transversely rugulose, moderately shining. Embolar 

 margins sinuate, turned down, practically on edge along middle, flaring apically ; 

 apical area of both embolium and corium polished ; cuneus polished, turned 

 half on edge. Hind tibiae moderately compressed, distinctly curved. Body 

 clothed with short, recumbent, in part sericeous, yellowish pubescence ; an 

 arcuate, silvery sericeous band across embolium and corium opposite tip of 

 scutellum, curving posteriorly for a short distance along inner edge of corium ; 

 as a continuation of this silvery band there is a longitudinal stripe along outer 

 edge of clavus, extending from a point opposite tip of scutellum to near apex 

 of clavus ; apical area of corium and embolium destitute of silvery bands.
