OF NEW ZEALAND. 511 



The femora are not much dilated, and the tibial hooks, though dis- 

 tinct, are not very large. The pubescence is scanty, and is chiefly con- 

 fined to the tibiae. 



This species resembles the female P. zealandicum, but is rather 

 smaller, and may be at once distinguished from it by the very distinct 

 depression across the vertex, just behind the eyes. 



Length, if lines. 



I found two examples near Whangarei Harbour. 



909. P. assimilata, n.s. Very similar to P. rufum, but of a 

 shorter and broader form, and dark reddish-chestnut colour, with the 

 head and front of thorax pitchy ; the eyes less prominent, and the club 

 of the antennae well-defined and rounded. 



Rostrum moderate, a little shorter than that of P. rufum, and stouter 

 than in P. zealandicum ; it is finely punctured, and the antennae are 

 inserted behind the middle. The head has a distinct line behind the 

 eyes, and the occiput is smooth and shining. Antenna stout, the scape 

 and funiculus of equal length, the club pubescent, very distinct, almost 

 circular. Prothorax triangularly ovate, a good deal rounded near the 

 base, and the sides rounded forwards to the very evident frontal con- 

 striction, which, however, leaves the upper part almost untouched ; the 

 disc is scarcely depressed, its punctation is more distant than that of 

 the sides, so that it exhibits a smooth, abbreviated dorsal line. The 

 elytra are a little wider than the thorax, rather short, very slightly 

 rounded laterally, and the apex obtusely rounded; they bear distinct 

 coarsely punctured striae, rather broad rugulose interstices, the three 

 sutural and the marginal reach the apex, and the others being shortened 

 leave an obvious depression near the apex. The thighs are not much 

 inflated, and the penultimate tarsal joint is a little dilated and bilobed. 



The body is nearly nude, but the antennae, legs, and apical portion 

 of the elytra are pubescent. 



Length, ij line. 



I found one mutilated individual near Whangarei Harbour. 



910. P. planiuSCUla, n.s. Allied to P. longirostre, but much less 

 convex, and at once distinguished from it by the form of the thorax, 

 which is longer, much more narrowed anteriorly, and with the frontal 

 constriction extending across it as a distinct depression, more distant 

 from the apex than in P. longirostre. The rostrum on its anterior por- 

 tion is longitudinally rugulose, the rest, as well as the head in line with 

 the eyes, is more coarsely and rugosely punctured, and behind the 

 moderately prominent eyes there is an obvious line separating the 

 smooth occipital portion from the front ; it is hardly as long as in 

 P. longirostre^ a little stouter, and very gradually narrowed posteriorly 

 with the antennal insertion exactly in the middle. The antenna are 

 long and stout, the thick, distinctly flexuose scape is rather longer than 

 the funiculus, the second joint of which is longer than those which 

 follow ; they are shining red, the oviform club being paler and pubes- 

 cent. Prothorax long, with indistinct basal margin, the sides rounded
