millimeters; between the lateral carinse presenting three pairs 
of lightly elevated, ill-defined protuberances of nearly equal 
distance apart; the first pair between the shoulders often sur¬ 
mounted by very thin variable short longitudinal supernumerary 
carinula, substraight; the second somewhat smaller pair, in pro¬ 
file, little elevated, situated in a plane drawn just behind the 
elytra, sometimes presenting obscure or short line on the summits; 
the third pair often inconspicuous,appear at about an equal distance 
behind ; between the frontal portion of the shoulders anteriorly, 
and behind each of the first and second pairs of dorsal protu¬ 
berances slightly f ossulate; median carina of pr onotum slightly con¬ 
spicuous very slightly elevated, irregularly undulate, posteriorly 
straight, obliterated forward just behind the front margin, some¬ 
times a very little compresso-elevated in front and between the 
shoulders ; humeral angles strongly obtuse, the lateral posterior 
apical carinse often continued forward on the shoulders as a 
supernumerary enclosing a narrow scapular area; above the 
infra-scapular area the shoulders being lightly bicarinate on each 
side; anterior prozonal carinae short straight, distinctly reduced 
but not obsolete; infra-scapular area narrow above the elytra, 
subsulcate ; lateral apical carinse posteriorly subobliterated, apex 
slightly obtuse or barely bifurcate ; posterior angle of lateral 
lobes of pronotum armed with one strong curved spine directed 
outward and forward nearly transverse ; lateral lobes divided by 
a distinct median sulcus ; the fronto-lateral margins of pronotum 
slightly enlarged, turned outward subtuberculate; lateral lobes 
posteriorly bisinuate, the elytral sinus shallow, the inferior sinus 
deeply angularly excavate, the posterior angle behind obliquely 
truncate. Elytra oblong acuminate toward the apex ; wings well 
developed though largely concealed by the pronotum, not extended 
backwards quite so far as the apex of process. Anterior femora 
slender a little compressed, ampliate toward the base, inferior 
marginal carina provided with two more or less variable tubercles 
or teeth ; middle femora slender, externally carinate above, but 
just below the superior marginal carina, margin below armed 
with two teeth ; posterior femora of moderate size granulate, 
superior marginal carina lightlya rcuate, crenulate, near the apex 
provided with two obscure ante-genicular teeth, genicular spine 
slightly prominent, inferior marginal carina armed with three or 
four more or less distinct teeth, the one behind the middle being 
conspicuous acute, directed backwards ; posterior tibial margins 
strongly expanded laterally, minutely crenulate, internal margin 
unarmed, external margin sometimes with one to five scarcely 
perceptible minute spines, lateral margins of first article of
