Antennae 22-jointed, but little longer than front femora. 
Eyes emarginate above by an encroachment of the occiput, 
which is convex. Vertex projecting considerably 
in advance of the scarcely prominent eyes, exca- 
vate at sides of the median carina, which is very 
prominent, and which rounds smoothly into the 
prominent, narrowly grooved facial costa in side 
view. Face rather strongly retreating. Pronotum 
distinctly and evenly tectiform (roof-shaped), gen- 
tly arched longitudinally, the median carina dis- 
tinct, front margin angulate or rounded-angulate, 
the hind process either caudate or abbreviate, ex- 
ceeding the hind knees by two or three millimeters, 
or falling Just short of them, the disk smoothly 
punctate, often with half a dozen minute longitu- 
dinal ridges. 
Color: pale buff to dark brown above, the sides 
darker, often almost black. Face and cheeks, lower half of sides 
of pronotum, and under side of body white or clay yellow in 
male, darker in female. A white spot is often present near end
