906. P. apicalG, n.s. This species resembles the typical one 

 (P. zealandicitm) so far as the New Zealand species are concerned, but 

 is considerably larger, more robust, and piceous-black in colour, with 

 pitchy-red antennte and tarsi. 



The. prothorax is triangularly-ovate, being widest at the base, where 

 it is joined to the elytra by means of a distinct neck, from thence it is 

 gradually and almost curvedly narrowed to the width of the head, with 

 an obvious constriction near the apex ; it is rather large and convex, 

 and its surface is moderately coarsely and almost rugosely punctured. 

 Sciitelhan small, triangular. 



The elytra are transversely convex, not very perceptibly narrower 

 than the thorax, very parallel-sided, and somewhat obtusely rounded, 

 with a slight sinuation, towards the apex ; they are striated, the stria3 

 have transverse punctures which encroach on the interstices, these are 

 rugulose, and somewhat bent and irregular near the apex; they are 

 abruptly declivous behind, and the apical margin is somewhat explana- 

 ted, so as to leave a very evident groove or depression between it and 

 the deflexed portion of the elytra. 



The femora are very much dilated and compressed, with a notch 

 below near the apex ; the tihicc are flexuose and terminated outwardly by 

 a strong curved spur ; the tarsi are comparatively slender. 



The eyes are rather prominent, much more so than in P. zealandicitm. 

 The head and rostrum are as coarsely punctured as the thorax, the
