PHYLA CTICUS. Ill 



Labrum transversely subsinuate. 



Maxillary palpi (Tab. IV. fig. 5 m, fig. 6 m) elongate, filiform ; 

 the basal joint obscure ; the second subdilated towards the apex and 

 obliquely truncate; the third longer and slightly broader (at the 

 apex) than the second ; the apical joint attenuate, much narrower 

 than the apex of the third. 



Labial palpi (Tab. IV. fig. 5 n, fig. 6 n) attenuate, subcylindrical, 

 the penultimate joint in P. modestus being somewhat more dilated 

 than in P. pollenosus or P. olivaceus. 



Antennas sufficiently robust, filiform (slightly dilated towards the 

 apex) ; the basal joint subelongate, inflected outwards, and slightly 

 incrassated ; the second short and ovate ; the third attenuated, and 

 somewhat longer than the first. 



Eyes prominent, situated at some distance from the base of the 

 head, lateral. 



Head depressed at right angles to the plane of the elytra, hardly 

 produced in front ; impubescent, and generally deeply marked trans- 

 versely or obliquely between the eyes. 



Thorax broader than the head, transverse (sometimes almost qua- 

 drate), not emarginate in front ; the sides are depressed and mar- 

 ginate, and towards the apex more or less constricted ; the surface 

 is generally equate, and impubescent. 

 Scutellum triangular. 



Elytra robust, broader than the thorax ; the humeral angles pro- 

 minent, slightly tapering towards the apex ; for the most part di- 

 stinctly punctate-striate, covered with a, fine pubescence. 



Legs : anterior femora robust, subcylindrical, slightly incrassated 

 near the apex. Tibia? inflected at their immediate base, straight (not 

 incurved), finely pubescent, cylindrical, not dilated towards the apex ; 

 the insertion of the tarsus is at the extreme apex. The tarsus (Tab. IV. 

 fig. 5 d) is short ; the basal joint is triangular, not broader than the 

 tibia ; the second joint of the same form, but much more minute.; the 

 third is more transverse, subcircular, the breadth being double that 

 of the basal joint, and almost bilobed ; these three joints are densely 

 clothed with rigid pubescence : the terminal joint is attenuate and 

 incurved, slightly dilated towards the apex, shorter in length than in 

 the adjoining genera: the claw is broadly bifid, and simple, un- 

 armed by any inner tooth. The posterior femora are (when viewed 

 transversely) incrassated, in form subovate. The tibia? (Tab. IV. 

 fig. 6 g) are short and robust, somewhat thickened at the apex and 

 base ; at the apex obliquely truncate, and terminating below the in- 

 sertion of the tarsus in a strong, double, hook-shaped process ; the 

 lateral marginatum is entirely unarmed by any spurs. The tarsus
