or less distinct longitudinal shallow groove with smooth, flat walls 
and a smooth patch on each side in the posterior part, the outer 
margins are simple or serrate; scutellum ogival; elytra sub- 
cylindrical, but a little depressed in the posterior part, faintly 
costulate or not and covering almost the whole of the propygidium 
which has a deep, median, longitudinal groove ; pygidium vertical, 
slightly convex, more or less cordiform ; abdomen not much convex 
in the male, more so in the female; pectus densely hairy ; legs and 
tarsi moderately long, anterior tibia uni- or bi-dentate outwardly 
and with a very small inner spur, posterior ones with an evanescent 
oblique keel, claws moderately long and with a vertical tooth under- 
neath a little before the median part; in the female the spurs of the 
hind tibiz are only very slightly compressed. 
The species included in this genus are extremely alike, and were it 
not for the shape of some of the antennal joints in the male their 
identification would prove almost impossible. On that account I 
do not propose, therefore, to split the genus into species with 
9-jointed or 10-jointed antenne or uni-dentate or bi-dentate tibia. 
The head and prothorax are deeply pitted, each puncture bearing a 
whitish scale and occasionally an erect hair, and the less deeply 
pitted elytra have bands of similar scales, sometimes interrupted, 
and alternating with denuded lines, while the pygidium and the 
abdomen, the latter especially, are densely scaly.
