line runs from the transverse mark to tlie apex of the elytra, the 

 extreme points of which are also scaleless. In some specimens 

 the thorax has the sides, and a small triangular patch on the 

 hinder part above, adorned with scales.

This species somewhat resembles the P. chlorolineatus, but 

 differs in being much larger ; the thorax has a transverse 

 metallic line in the middle, which towards the sides bifurcates, 

 and, joining with a line on the lateral margin, encloses an irre- 

 gular area : on tlie hinder half of the thorax above is a lon- 

 gitudinal line, and on the hinder margin is a transverse line : 

 on the thorax beneath is a longitudinal line between the legs, a 

 transverse line behind, and another in front ; these, together with 

 that on each side of the thorax, enclose two nearly square areas, 

 and from the middle of each, one of the anterior pair of legs 

 has its origin. The elytra have a transverse metallic line in the 

 middle, and another runs parallel with and close to the outer 

 margin as in P. chloroUnealus ; there is also a longitudinal line 

 extending from the base of each elytron, near the middle, (but 

 rather nearer the suture than the outer margin,) and extending 

 almost to the central transverse line, as in the species just men- 

 tioned ; and, on the apical half of the elytra, are two other longi- 

 tudinal lines, which extend from the central transverse line and 

 join the marginal one near the apex of the elytra, sending off a 

 small branch near the junction of the two; this line does not (as 

 in P. chlorolineatds) form as it were a continuation of the longi- 

 tudinal line on the basal half of the elytra, but is more removed 

 from the suture. Another difference consists in there being a 

 line along the suture on the apical half of the elytra in the present 

 species. I can perceive neither stria; nor punctures on the elytra : 

 the tliorax is also smooth, but appears to be slightly indented 

 where the metallic scales form lines. The rostrum is very broad 

 and nearly flat, but there is a tolerably deep transverse indentation
