part, not convex except in the posterior, deeply and somewhat 
closely punctured, and with the costules very plain; pygidium and 
abdomen as deeply and quite as closely punctured as the elytra,

LERIBH, n. gen. 
Mentum deeply foveate, sparingly villose, gradually and roundly 
ampliated from the base to the ligular part which is fused with the 
mentum, and broadly and deeply emarginate in front, the labial 
palpi are inserted on the outer face of the mentum, close to the 
sides, basal joint very small, nearly sunk into the cavity, last one 
longer than the two, swollen outwardly ; maxille robust, concave, 
without any traces of inner lobe, the upper margin is strongly 
angular outwardly and has five sharp teeth arranged in a row, the 
maxillary palpi are inserted quite close to the projecting upper angle 
of the maxille, the two intermediate joints are sub-moniliform, and 
the apical one which is longer than the other three taken together 
is thickly fusiform; clypeus parallel, truncate in front and reflexed, 
plainly grooved transversely before the median part, and separated 
from the head by a frontal suture, the anterior vertical part of the 
clypeus is triangular, and there are no traces of a labrum, the head 
is as long as the clypeus, and has no ridge on the vertex, the eyes 
have no superciliary keel; in the male the antenne are 10-jointed, 
the pedicel consists of four joints, the second of which is thickly 
moniliform, the third is as long as the first, the fourth is compressed, 
sharply aculeate inwardly, and is about one-sixth as long as those 
forming the 6-jointed club which is longer than the pedicel; pro- 
thorax ampliated laterally in the median part, and with the posterior 
angles rounded, not pubescent along the anterior margin; elytra 
sub-cylindrical, not covering the propygidium; pygidium convex, 
semicircular, slightly drawn forwards, abdominal segments con- 
tractile, basal one nearly completely hidden by the coxe; all 
femora robust; anterior tibia bi-dentate outwardly and with an 
inner spur, tarsi moderately long and with the joints slightly 
dilated at apex, and glabrous underneath, claws long, slender,
