compared with the males, are in general stouter and more robust 

 with the antennje and tarsi less slender and elongated — and have 

 the hind body much less pubescent, the outline of the latter from 

 the hind cox;\3 to the apex (viewed from the side) being straight 

 or somewhat convex, while in the males it is concave.

The pitchy black markings on the elytra are all longitudinal, 

 and are placed as folloAvs : — Three (the middle one on the suture) 

 running from the base a short distance hindward, one on each 

 elytron (beginning between the hinder part of the sutural and 

 external anterior marks) reaching to considerably behind the 

 middle, one close to the external margin behind the shoulder, and 

 three or four placed side by side between the hinder part of the 

 elongate juxta-sutural mark and the lateral margin. 



Compared with P. Lacordairei, the antennas are considerably 

 more slender than in that species ; the prothorax is pubescent, 

 narrower, its greatest width nearer the middle, a little flattened, 

 more strongly and very much more closely punctured ; the 

 femora unarmed ; the tarsi (especially the intermediate) longer 

 and more slender, the elytra not distinctly striate in any part 

 but with the interstices between the rows of punctures distinctly 

 subcarinate here and there. The unarmed hind femora will 

 separate the present species from all previously described in the 

 genus unless it be imchytoides, Baly, the hinder femora of wdiich 

 are uncharacterised — but that species diflers from the present 

 one inter alia in having the surface of the prothorax " rugose, 

 coarsely punctured."
