 yellowish white, inner margin near the apex of the scutellum 

 broadly yellow ; abdomen above yellow with black margins, or with 

 the basal segments entirely dark. Central facial keel sharp, forked, 

 and becoming indistinct on the forehead. Scutellum three-fourths 

 longer than pronotum, its side keels straight, strongly diverging, 

 sometimes with a black spot on each side at the base, or black with 

 the apex yellow. Elytra scarcely two-thirds so long as abdomen, 

 hind margin broadly rounded, nerves finely granulate. Legs 

 slender, spur of hind tibise large and wide. ' Pygofer, seen from 

 behind, distinctly wider than high, and having three blunt angles, 

 namely, one just below the middle of each side, and one in the 

 middle of the lower margin. Viewed from the side the nearly 

 horizontal margin of the upper notch forms an obtuse angle with 

 the hind margin, which is oblique and nearly straight ; the rounded 

 right angles, in which the hind joins the lower margin, coincides 

 with the point of the greatest width of the pygofer, when seen 

 from behind. Styles straight, strongly diverging, narrow- triangular, 

 Ijointed, reaching half the height of the cavity of the pygofer. 

 Teeth of anal tube distant, slightly curved outwards at the apex.
