declivity, tlir fjtli are less evidently noditonn and hai-dly at all elevatefi 

 alonj; the disc. 



Underside rufo-fuscous. MetasternTUii with transverse series of 

 granules. Basal ventral segment granulate, rather longer than any ot 

 the intermediate ones, each of which has a well-marked transverse im- 

 pression between the middle and sides, the 5th as well as the jHeceding 

 two are without granules, all have deep sutures. 



Antennae 11- jointed, the 1st and 2nd joints thick, 3rd about twice as 

 long as broad, 4-9 small and submoniliforin ; club broad, biai-ticulate. 



This may prove to be a local form of 2770, P. tricnvus.

 decaying leaves in April, 1!)12. 



Ohs. — P. nifirornis, 2708. From the same source I have several 

 specimens of a vai'iety of this dark-legged and sliglitly lai-ger species. 

 These differ fi-om P. pallois by the absence of the lateral depressions on 

 the intermediate ventral segments, as well as in other details. I found 

 my twn specimens of 2768 in the North Island, on Mount Pirongia, in 

 December, 1892.

Elongate, subparallel, very sliglitly convex, glabrous, moderately 

 nitid ; piceo-rufous, antennae and legs rathei' palei'. 



Head narrower than the thorax, distinctly Init not very closely 

 punctate, its sides obtusely elevated between the antennae and eyes. 

 Thorax hardly any longer than broad, slightly wider near the front than 

 behind, lateral margins distinct and forming the rectangular posterior 

 angles; apex subtruncate in the middle, with a short sinuosity behind 

 each eye, its subacute angles, however, do not extend fui-ther forwards 

 than "^hc middle; discal impression broad but not deep, longitudinally 

 divided by a smooth line, as coarsely but not as closely punctured as 

 the sides. Elytra twice the length of the thorax, a little wider near 

 the middle than at the base, a good deal narrowed towards the ex- 

 tremity; base arcuate-emarginate, the subacute humeral angles are but 

 little wider tlian the tlioiax and scai-cely project beyond its base; their 

 striae are modei-ately deep and regular, the pair at each side of the 

 suture are deeper at the base, their punctures are distinctly separated 

 and rather elongate but not coaise; interstices rather broader and less 

 convex than the outer ones, with fine serial punctures; the suture is 

 bent outwards and subcarinate at the apices. 



This most nearly approaches /'. arcuatiis, '}408, but is smaller, more 

 slender, and more rufescent. The thoracic impression is shallow, and 

 the shoulders are not thickened and prominent. 



Eyes moderately large; terminal antennal joint rather narrower 

 than the 10th and distinctly marked off.
