Chestnut-brown, shining, club of antenne flavescent; head and 
clypeus covered with nearly contiguous punctures, clypeus in the 
shape of a broadly truncate cone with the margins raised in the male, 
while in the female the anterior outer angles are rounded and the 
anterior margin very slightly sinuate, the clypeal ridge is ante-median, 
transverse, and plainer in the male than in the female, the 8-jointed 
flabellate club of the g is equal to two-thirds of the length of the 
whole head, the inner joint is two-thirds of the length of. the other 
joints ; in the ? the club proper is 3-jointed and much shorter than 
in the g, but the three joints preceding, 7.e., the seventh, sixth, and 
fifth, are plainly laminate but decrease in length, the seventh joint 
being half the length of the following one, and the sixth and fifth 
decreasing in proportion; prothorax narrowed laterally in the ¢ 
from near the median part to the anterior angle which is strongly 
produced, nearly straight thence to the posterior angle, which is 
plainly rounded, moderately convex in the central part of the disk, 
covered with somewhat small, round punctures divided by a smooth 
interval equal in width to their own diameter; in the ? the pro- 
thorax is broadly rounded and ampliated laterally and equally 
narrowed towards the anterior and posterior parts; scutellum 
sharply ogival, depressed, and punctulate on each side of a 
median longitudinal raised line; elytra plainly wider at the base 
than the basal part of the prothorax, not sinuate laterally past the 
shoulders, humeral callosity very little pronounced, but slightly 
more so in the 9 than in the g, moderately convex and covered 
with slightly rugose, unequal punctures very closely set, and having 
in the dorsal part three geminate punctulate strie the intervals of 
which are slightly costulate in the ? but not in the g, the two lateral 
striz or costules respectively are very faint; the propygidium is 
closely punctate but covered for the greatest part by the elytra; 
pygidium plainly convex in both sexes, and having an apical fringe 
of long, flavescent hairs; abdomen convex, each abdominal segment 
deeply punctured and with a transverse series of flavescent hairs; 
pectus closely punctured and moderately densely clothed with long, 
flavescent hairs; anterior tibiae bi-dentate outwardly, and with the
