tened laterally and nearly triangular as seen from a side view; 
no suprahumeral horns; posterior process heavy, curved, cari- 
nate above, tip compressed below into a sharp keel, just reaching 
internal angles of tegmina; tegmina black, punctate, pubescent 
and coriaceous at base, bronze and coriaceous from base as 
far as apical end of posterior process, apical end fuscous hyaline; 
legs and undersurface of body uniform brown. 
Head subquadrangular, broader than long, very dark brown, 
roughly sculptured, finely punctate, sparingly pubescent with 
~ long golden hairs; base strongly sinuate, raised above ocelli; 
eyes large, brown, prominent; ocelli small, pearly, inconspicuous, 
farther from each other than from the eyes and situated well 
above a line drawn through centers of eyes; genz curved, edges 
produced forward in a slight flange; clypeus broad, extending 
for half its length below the lateral margins of the gene, tip 
semicircular, strongly pilose; antenne slender and black. 
Pronotum very dark brown, covered with dense golden pubes- 
cence, finely punctate, single pronotal crest raised in a laterally 
compressed elevation on median dorsal line, this elevation not 
quite as high as its width at base, nearly triangular, tip rounded 
and blunt, center of crest slightly posterior to humeral angles, 
both front and back margins sloping but front margin more de- 
clivous; humeral angles broad, heavy, blunt; no suprahumeral 
horns; metopidium strongly convex at median line; median 
carina percurrent, only faintly indicated on metopidium but 
very sharp on posterior process; scutellum present but entirely 
concealed by pronotum; posterior process heavy, impinging on 
tegmina, curved, blunt, strongly carinate above and extended 
below at tip to form a narrow bladelike keel, tip just reaching 
the internal angles of tegmina. 
Tegmina narrow, pointed; base black, punctate, and coria- 
ceous, this portion extending farther along the costal than the 
internal margin; the area extending from this black coriaceous 
portion to a point as far caudad as the apex of the posterior 
process is shining dark brown and more or less opaque and ends 
in a rather definite margin; the apical portion of the tegmina 18 
hyaline with the tip slightly tinged with fuscous; veins proml- 
nent and strongly pilose; free margin beyond veins narrow and 
slightly wrinkled; five apical and three discoidal areas. 
Undersurface of body entirely brown with dense golden pubes- 
cence which changes to a silvery tinge on the undersurface of 
the abdomen. 
Legs simple, very dark brown, strongly pilose.
