hairs and moderately conspicuous ; hind femora not much wider 
than intermediate, confusedly punctured all over their under- 
surface, and with the inner apical angle prominent hut rounded 
off ; claws strongly bifid.

Sat brevis ; postice leviter dilatatus ; minus nitidus ; setis 
longis erectis ferrugineis minus crebre vestitus ; vix perspicue 
punctulatus ; labro clypeura leviter superante ; antennis 8-arti- 
culatis ; unguiculis bifidis. [Long. 2?, lat. 1? lines. 
The upper edge of the turned up labrum is wide, slightly angu- 
lated in the middle and rises aVjove the surface of the clypeus; the 
latter is scarcely concave in front and has no reflexed margin in 
the part overtopped by the labrum ; it is distinctly .separated from 
the rest of the head by a well-defined impressed slightly arched 
sucure ; the whole surface of the head is rugulose rather than 
distinctly punctured. The prothorax is scarcely half again as 
wide as long, its base bearing a similar proportion to its front 
margin which is gently concave with angles sharp but little pro- 
duced ; its sides are rather strongly rounded, the hind angles 
(viewed from above) being scarcely defined ; the base is moder- 
ately bisinuate with a fairly defined lobe ; the surface is obscurely 
aud faintly uneven but without defined puncturation. The surface 
of the elytra beai’s a faint sculpture similar to that of the pro- 
thorax, and in addition a row of fine granules close to the suture 
on either side, outside which is an obscure indication of a stria 
(noticeable only in certain lights) ; the lateral fringe is hardly 
distinct from the erect pilosity of the surface and is not conspi- 
cuous round the apex, which has a distinct membranous border. 
The sculpture of the underside is quite obsolete. The hind coxte 
are scarcely shorter than the metasternum and are (on the ex- 
ternal margin) quite twice as long as the second ventral segment. 
The ventral series consist of very long fine hairs. The hind 
femoi’a are v^ery broad, their inner apical angle defined but not 
in the least produced, their surface bearing the usual coarse serial
