Mentum broad, transverse, nearly straight laterally, being only 
very slightly sinuate near the point of insertion of the palpi, narrowly 
incised in the centre of the anterior part which is quite straight 
with the angles sharp, there is no trace of suture dividing the ligular 
part from the mentum ; the apical joint of the short labial palpi is a 
little shorter than the second, slightly fusiform and slender ; maxille 
with a sharply trifid tooth at the tip and an inner, somewhat ciliate 
one, apical joint of maxillary palpi a little shorter than the two pre- 
ceding ones taken together, slightly fusiform at base, truncate at the 
tip; mandibles robust, concave, tri-dentate at the tip, and lined 
inwardly with a broad, briefly villose membrane ; head with a sharp 
clypeal carina, clypeus with the margin slightly reflexed, vertical 
part narrow, labrum short and very broadly incised; antenne 10- 
jointed, basal joint moderately long, second one moniliform, third to 
fifth short, of equal length, set close to each other, sixth and seventh

little shorter than the whole pedicel (3); prothorax convex, plainly 
ampliated laterally in the median part; elytra slightly broader at 
the base than the base of the prothorax, ampliated laterally from 
about the median part, convex, and covering half the propygidium 
which is somewhat convex and vertical; pectus densely villose ; 
anterior tibiz tri-dentate ; posterior ones somewhat broadly dilated 
at apex, the spurs are flattened, rounded at the apex, the upper one
