but as it has a very weak, almost obsolete denticle, it may also be 
mentioned in the group with tri-dentate anterior tibia where it will 
find its place next to Stenoserica. The sternum is narrowed between 
the middle cox, without independent process, it borders on the 
hairy mesosternum, with a small curved line; the surface is hairless, 
shiny; the antenne are 10-jointed, the club 3-jointed in both sexes ; 
the clypeus is small, tri-toothed with a transverse keel before the 
frontal suture; mentum with a brush of dense hairs in the male, 
deplanate in front and without sharp border in the female; pro- 
thorax little traverse, without sinus in front; hind cox abbreviated, 
little longer externally than the episterna, fore segments of abdomen 
remaining free; hind femora or tibizw widened, but not flat, all the 
tarsi slender, the anterior ones not shortened, the basal joint of 
hind tarsi very short, scarcely half as long as the second, claws 
deeply cleft, the sharp upper teeth slender. Only one species 
known.” 
I have not met as yet with this genus, which seems to be most 
closely allied to Camentoserica, if it differs from it.

Loe. cit., p. 453. 
‘Both sexes: Brown, shining, head and prothorax somewhat 
more reddish, narrowly ovate, finely punctate, clypeus broad, the 
ocular keel bends before the eye suddenly with a curve into the 
lateral margin, the anterior margin is distinctly sinuate with the 
centre projecting, the angles are distinctly rounded, concave, smooth, 
the short space as far as the curved, transverse keel is almost 
smooth, and very densely punctate and finely wrinkled thence 
to the frontal suture; prothorax little broader than long, the 
anterior angles not prominent, the middle a little prominent, the 
sides weakly ampliated in the middle, little rounded posteriorly 
with blunt, rounded hind angles and weak marginal hairs, the 
surface densely and finely punctate; the elytra are similarly 
punctate, the suture and three or four narrow ribs are smoother, 
the intervals seeming broad, because the odd ribs between them 
are obsolete; pygidium convex, densely punctate, acuminate; the 
abdominal segments are finely punctate and strongly setose, the 
penultimate segment longer in the middle than any of the pre- 
ceding ones; hind femora ovately convex in the middle, smooth 
with a few weak setigerous punctures, hind tibiz a little widened, 
elongated, densely punctate, and having externally two weak bristle-
