strongly elevated from below the scutellar striola, the punctures 

 rather small, the expanded margins, owing to a contraction of 

 the sides of the disk, broadest at the middle, behind very distinctly 

 reflected ; body beneath and femora very glossy chestnut-brown ; 

 antennae, tibisB, tarsi, and epipleurse of the elytra reddish ferru- 

 ginous" (Pascoe).

It is with some doubt that I place this and the two following 

 species in this section. I have never seen any of them. They are 

 described by Pascoe, as being intermediate between P. Walheri 

 and P. silphoides in form, but no indication is given of their relative 

 length or breadth. I think they must approach very nearly to some 

 of the insects grouped in the next section.

" Dark brown (or sometimes light reddish brown), paler at the 

 margins, less glossy than the last ; head rather narrow behind the 

 antennary ridges ; the clypeus very convex, its suture above 

 indistinct, but forming a well marked groove on each side ; 

 the eyes widely apart ; prothorax not broader than the elytra at 

 their base, much longer and nari'ower than in the last, the basal 

 foveoe represented by a large shallow depression on each side ; 

 scutellum transversely triangular, the sides curvilinear ; elytra 

 gradually narrowing from the base, the sides of the disk not 

 contracted, seriate-punctate, the intervals of the rows not raised, 

 the punctures rather small, the expanded margins of nearly equal 

 breadth, or only very gradually narrowing behind, the suture 

 raised as in the last ; body beneath and legs glossy chestnut-brown ; 

 antennae glossy ferruginous" (Pascoe).
