This species is about equal in size to P. moniliferus, but is of a 

 narrower form, and has the thorax more globose. It may be dis- 

 tinguished from either of the other species by its brass green 

 colour. The head and rostrum are impunctate ; a slight central 

 longitudinal groove is observable on the hinder part of the latter, 

 and on each side of this are two shallow oblong foveae, these and 

 the central groove abut against the distinctly elevated anterior 

 portion of the rostrum ; a small golden spot is situated under 

 each eye. The thorax is globose and more distinctly constricted 

 behind than usual ; on the upper surface is a smallish round spot 

 on each side situated about midway between the base and apex of 

 the thorax, and there is another on each side just above the base 

 of the femur. On the elytra are sixteen tolerably large round 

 spots, these are nearly equi-distant and disposed as follows : — four 

 form a transverse row at the base of the elytra ; near the middle 

 is another band of four spots, and between this and the apex of 

 the elytra is a third band of six spots, and, lastly, there is a spot 

 near the apex of each elytron.

About equal in size to the P. moniliferus ; but the thorax is 

 broader and rather shorter than in that insect, and the elytra 

 rather more elongated. Rostrum with tlie basal half flat or 

 slightly concave above and with a longitudinally impressed line, 

 the fore part humped or elevated above the plane of the hinder 

 portion. Thorax impunctate, nearly globose, but truncated before 

 and behind, with two round spots above about midway between 

 the base and apex, and a patch on each side just above the inser- 

 tion of the leg. Elytra convex, ovate, with rows of distinct 

 punctures. On the elytra are twenty spots, four of which are 

 arranged in a transverse line near the base ; six others form a 

 parallel I'ow near the middle of the elytra ; this is followed by a 

 band of eight spots ; and, lastly, there is a spot on each elytron 

 near the apex. These spots are nearly round and of moderate
