516 Coleopterological Notices, VII. 



Head feebly declivous, exserted and borne on an elongate and 

 rather strongly but not abruptly constricted neck, almost similar 

 to that of the Lophioderini, and, in an almost similar manner, the 

 dorsal surface of the neck and basal parts of the vertex are 

 deeply excavated. Eyes large, convex, median and prominent; 

 front narrowed and gradually elevated beyond the eyes, the an- 

 tennae attached under the tip and approximate at base, monili- 

 form, gradually and feebly incrassate, devoid of distinct club, and 

 equally strongly sculptured and finely, though not densely, pubes- 

 cent from base to apex. Clypeus very short, not visible from 

 above, broadly and very feebly sinuate at apex, the labrum large, 

 transverse, circularly sinuate at the middle, the apices more nar- 

 rowly rounded. Mandibles short, very stout, arcuate, somewhat 

 angulate externally near the base, the apices acute but not finely 

 aciculate. Third palpal joint large, stout, finely and densely 

 pubescent, the fourth represented by a large and oblique, feebly 

 convex and spongiose apical truncature; it is attached to the 

 short and stout second joint by a small, abruptly curved and bulbi- 

 form peduncle. Labial palpi minute, slightly dilated and strongly 

 setose at apex. Mentum rather small, subquadrate, its surface 

 strongly convex. Maxillary cardo large and conspicuous, the 

 lobe elongate, densely setose at tip and more sparsely and 

 coarsely so along its outer edge. Prothorax strongly carinate at 

 each side toward base, the prosternum well developed, flat, twice 

 as wide as long and denselj^ pubescent before the coxae, which are 

 ovo-conoidal and contiguous, their cavities confluent, broadly 

 open behind and closed by the mesosternum, which is horizon- 

 tally and shallowly biexcavated for the reception of the coxae ; an- 

 terior margin of the double acetabulum cuspid ; trochantin com- 

 pletely wanting. Mesosternum tumid and elevated above the me- 

 tasternum, slightly prominent along the middle anteriorly but 

 scarcely carinate, sending a long process between the middle 

 coxae, the latter conical and rather narrowly separated ; side- 

 pieces tumid and pubescent as usual. Metasternum large, 

 densely pubescent along its entire anterior margin, finely carinate 

 along the middle, gradually more strongly anteriorlj^, the carina 

 obsolete posteriorly ; parapleurae concealed by the elytra but' 

 turned inward slightly behind to meet the hind coxae, which are 

 small, oval and very remotely separated, more so than in any 

 other genus of the family, the metasternal edge between them
