arcuate, in front strongly roundly produced, behind the middle more 
largely elevated curvate, backward the margin at the apical fourth in¬ 
distinctly quadri- or quinque-undate or subsinuate at the obtuse apex; 
superior margin rather widely longitudinally sulcate ; anterior pro¬ 
cess subobtuse, the apex strongly bidentate, inferior lateral margins 
viewed from above strongly serrate, viewed from the side strongly 
oblique, substraight or little curvate produced over the head ; pro- 
notum posteriorly extended distinctly beyond the femoral ajjices ; 
lateral lobes posteriorly bisinuate, the upper sinus very shallow, 
posterior angles strongly oblique, subobtuse and obliquely excised 
behind. Elytra oblong ; wings not visible. Anterior femora com- 
pressed-foliaceous, superior carina serrulate-undate, below subquadri- 
lobate, middle femoral carinae above comjiressed, serrulate-undulate, 
below strongly quadrilobate, or the two middle lobes fused in one, 
then trilobate ; posterior femora rugose, superior cai'ina crenulate 
(in the female bearing four tubercles), and the apex triangularly 
elevated; superior area before the knee bispinose, external pagina sub- 
tuberculate, as viewed from above the inferior external carina strongly 
trilobate, the first very small, ventral carina strongly quinque-lobate 
and finely serrate between the lobes. Colour rufescent, infuscate on 
the pronotum, the rest of body lighter. 
Length of pronotum, $ 11'5 mm. ; posterior femora, 5 mm. 
pronotum, 10'5 mm. ; posterior femora, 4'3 mm.

(See preceding table.) Lateral carinae of frontal scutellum 
minutely spinulose or denticulate. Pronotum subscabrous-granu- 
late, highly elevated, very thinly compresso-foliaceous, sides 
bearing radiating veins, conspicuous when held against the light, 
superior margin of crest nearly semicircular, but very little sub- 
angulate-rounded above the middle, the anterior half regularly 
smoothly curvate, the edge above somewhat widely longitudinally 
sulcate, little planate, posterior half curvate, but the margin at the 
apical third part minutely crenulate, and here toward the apex 
slightly undate and little sinuate above the apex (more distinct in 
the female), anterior process subobtuse, the front border arcuate 
and the apex bidentate, and just above in front little denticulate ; 
inferior lateral borders of anterior process strongly oblique, produced 
beyond the head, margin substraight, but viewed from above later¬ 
ally serrate ; posterior j^rocess extended backward little beyond the
