1244 COLEOPTERA 



2190. P. dlversum, n.s. Subcylindrical, bearing some minute 

 greyish hairs, shining, red, the legs and antennal club paler. 



Rostrum short, not longer than the head, parallel, moderately 

 finely punctured. Antennce inserted almost behind the middle, 

 second joint of the funiculus longer than the third ; club distinct, 

 broadly oval. Head twice the breadth of the broad rostrum, large, 

 subglobose, dilated behind the eyes, between these the sculpture is 

 like that of the rostrum, behind them it is much finer and more 

 distant. Thorax much narrowed and constricted in front, but, near 

 the base, almost wider than the hind-body, its punctuation moderate, 

 there is an indistinctly-raised, smooth dorsal line, and the apical 

 portion is nearly smooth. Scutellum small, polished. Elytra cylin- 

 drical, apices slightly explanate, they are punctate-striate, the striae 

 deeper behind, interstices with fine serial punctures. Tarsi narrow, 

 third joint not bilobed. 



There are two similar species, P. macrocephalum and P. cephalotes. 

 From the latter this species differs in having distinct, though fine, 

 punctures on the back part of the head; the elytral interstices are 

 not very narrow, and the third, fifth, and seventh are more or less 

 elevated behind ; the striae are rather deep, their punctures are not 

 dense, the intervals being nearly as large as the punctures them- 

 selves. 



Since describing P. macrocephalum I have received from Mr. 

 Cheeseman two or three varietal forms which he found on Mount 

 Arthur. In these the elytral striae are deeper than in the typical 

 specimen from Otago, and the punctures are closer. The underside 

 is distinctly punctured, and bears rather elongate yellow hairs ; the 

 metasternum is canaliculate on the middle, and is also broadly im- 

 pressed behind ; the basal abdominal segment too is grooved. 



Length, If lines ; breadth, f line. 



Clevedon. Oue female, from Mr. G. Munro. 



2191. P. nubilum, n.s. Shining, elongate, narrowed ante- 

 riorly, bearing slender minute hairs ; rostrum, thorax, and antennae 

 red ; legs paler ; elytra of a chestnut-red colour, but clouded or suf- 

 fused with darker marks. 



Hostrum shorter than the thorax, narrow, cylindric, slightly wider 

 in front than behind, finely and distantly punctured. Head some- 

 what dilated and nearly smooth behind the eyes, not constricted ; 

 eyes slightly prominent behind, but somewhat flattened in front. 

 Antennce, inserted behind the middle of the rostrum, the scape 

 gradually thickened ; second joint of the funiculus nearly as large 

 as the first ; club ovate, well limited. Thorax gradually but con- 

 siderably narrowed anteriorly, a little constricted in front, not wider 

 behind than the elytra, posterior angles obliquely rounded; its 

 punctuation moderate, not close. Elytra cylindrical, very slightly 

 explanate behind ; moderately punctate-striate, the striae deeper 

 behind, interstices with fine serial punctures and quite rugose. Legs 

 pubescent ; third joint of the tarsi not distinctly bilobed. 



Like No. 1306 ; the rostrum, however, is not so much contracted
