but as it has a very weak, almost obsolete denticle, it may also be 

 mentioned in the group with tri-dentate anterior tibiae where it will 

 find its place next to Stenoserica. The sternum is narrowed between 

 the middle coxae, without independent process, it borders on the 

 hairy mesosternum, with a small curved line ; the surface is hairless, 

 shiny ; the antennae 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 coxae abbreviated, 

 little longer externally than the episterna, fore segments of abdomen 

 remaining free ; hind femora or tibiae 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.

" 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 tibiae a little widened,, 

 elongated, densely punctate, and having externally two weak bristle-
