Very close to P apicale, but differs, besides in the coloration, in 

 haying the antennas a little broader ; the ninth and tenth joints are 

 not transverse. The rostrum is very smooth, only punctured at the 

 sides and at the base. The four anterior femora aro tipped with 

 blank ; the posterior pair are black, except at the extreme base. 

 The middle posterior areolet of the thorax is black anteriorly. The 

 sculpture of the elytra is more regular and distinct ; two of the costce 

 are very strong at the base.

Head shining ; rostrum three-quarters of a line in length, mode- 

 rately broad at the base, narrowed at the apex ; labrum and palpi 

 pitchy, the former longer than broad, acuminate at the apex ; eyes 

 prominent, black. Antennae about three-quarters the length of the 

 elytra, black, except the basal joint, which is pitchy ; third joint 

 three times the length of its greatest width, the lower anterior angle 

 produced, the produced part one-sixth the length of the entire joint ; 

 the fourth to tenth joints gradually increasing in length, but all 

 shorter than the third, distinctly and regularly narrowed to their
