OF NEW ZEALAND. 449 



very strongly inflated, and excised towards the extremity ; the tibia are 

 flexuose, quite unarmed apparently at the apex either with spur or spine, 

 but the apex, particularly of the two hind pairs, is cavernose, and in the 

 cavity the tarsus is inserted ; the tarsi have (anterior) the two basal 

 joints triangular, the penultimate expanded and truly bilobed, the apical 

 elongate, claws simple ; the hind tarsi are much more elongate. The 

 anterior coxa are large, globose, and contiguous, the intermediate are 

 circular, moderately embedded, and separated by a rather narrow 

 lamina, the posterior distant. The first abdominal segment is the 

 largest, the ante-penultimate the smallest, second separated from the 

 first by a strongly curved suture, sixth deflexed ; metasternum short, 

 angularly excised behind to receive the intercoxal process. 



This new form, though in some respects similar to Erirhinus, is, 

 nevertheless, quite distinct ; the only exponent is an inhabitant of the 

 sea-shore. 



789. P. testacea, n.s. Antenna, fusco-testaceous, very finely 

 pubescent. Rostrum of the same colour as the antennae, indistinctly 

 tri-carinated, the furrows transversely strigose. The thorax is variable 

 in colour, in some examples testaceous, in others fuscous, and is mode- 

 rately shining ; it is punctate, with an almost imperceptible smooth 

 dorsal line, and is clothed with pallid hairs. The elytra have on each 

 eight punctured striae, the third and sixth, as well as the fourth and 

 fifth, are confluent posteriorly ; the interstices are nearly flat, and are 

 finely punctulate ; the ground-colour is testaceous or fuscous, the dis- 

 coidal portion generally the darkest, and they are clothed with pallid 

 hairs. The under-side is punctulate, finely pilose, and of the prevailing 

 colour. 



Length, 2 lines ; rost. excl. (Rost. f line). 



I found this species amongst the stunted marine herbage just beyond 

 high-water mark at Marsden Point, Whangarei Harbour.

Schosnh. ; Lacord. Hist, des Ins. Coleop.^ Tom. vi., ^.476. 



Rostrum more or less elongated, slender, cylindrical, arched ; its 

 scrobes beginning between the middle and the extremity, almost rectili- 

 near and attaining the eyes. Antenna more or less elongate, slender; 

 scape thickening gradually; first and second joints of the funiculus 

 elongate, the former the larger, joints three to seven shorter, obconical, 

 or almost turbinated ; club oblong-oval, articulate. Eyes briefly oval, 

 transverse. Prothorax transversal, usually a little convex, more or less 

 rounded laterally, truncated at base and apex, with feeble lobes, some- 

 times rather distinct. Scutellum small, punctiform, or triangular. Elytra 

 oval or oblong-oval, narrowed behind, a little wider than the prothorax, 

 and slightly emarginate at their base. Legs of at least moderate length ; 

 femora clavate, often almost pedunculate at their base, unarmed ; tibia 

 slender, more or less flexuous, mucronated at the extremity ; tarsi
