628 COLEOPTERA 



Very similar to P. suffusus, but rather smaller and narrower, with the 

 sculpture of the upper surface more distinct and regular. The thorax 

 is sparingly but distinctly and rather deeply punctured. The elytra are 

 rather irregularly punctured, but the punctures are almost arranged in 

 rows, and the humeral folds are elongate and take the form of elevated 

 interstices on the basal portion of the elytra. 



A single individual was sent me some time ago from Tairua by 

 Captain Broun. It is no doubt a male ; the fourth abdominal segment 

 is completely abbreviated in the middle, and the apical dorsal segment 

 much inflexed, so that the form of the hind body is nearly, if not quite, 

 that of the section Camptosomes of Chapuis, rather than that of the 

 Cycliques to which the Eumolpides belong in his classification. 



1103. P. robustllS, n.s. Of a glossy bronzed-brown colour above, 

 with testaceous spaces near the shoulders and apex of the elytra, and 

 sometimes along the middle of the thorax ; legs and palpi yellowish, 

 antennae reddish towards their extremity ; under-side dark and shining, 

 the fifth ventral segment testaceous. 



The head is scarcely immersed up to the eyes, large, a little uneven, 

 with a depression behind, but very few punctures. The prothorax is 

 unusually large, finely margined, not very much broader than long, 

 considerably dilated laterally near the middle, obliquely narrowed 

 anteriorly, front angles depressed and almost acute, the sides behind 

 more abruptly, but less, narrowed than in front, and the basal rim pro- 

 longed to form the acute prominent hind angles ; the surface is uneven, 

 and has very few punctures on it. Scutellum curvilinearly-triangular. 

 Elytra obovate, not quite so broad as the middle of the thorax, with 

 almost regular rows of punctures, substriate near the apex; the punctures 

 on the disc are finer than those on the thorax, a little coarser near the 

 sides, and there is an abbreviated stria behind the shoulder; the humeral 

 region is obtusely elevated, but without distinct folds. 



The legs are long and very stout ; the anterior tibia are a good deal 

 bent, incrassated apically, rugosely punctate, and grooved externally ; 

 their tarsi robust, with a dilated basal joint, cordate in form ; the second 

 triangular, emarginate at apex ; third bilobed ; fourth elongate. 



Antennce robust, their second joint transverse, joints three to ten 

 about equal to one another, eleventh oval, they are pilose. 



Abdomen punctulated, sparingly clothed with fine grey hairs. 



Length, 2j-2 ; breadth, i-J line. 



These are the measurements of two set-out specimens, the smaller of 

 which, I think, is the female, the breadth was taken across the thorax, 

 though the middle of the elytra is of nearly equal width. 



On comparing the two preceding species with this one it will be at 

 once noticed, that P. robustus is much more robust, the prothorax larger 

 and more dilated laterally, the elytra relatively smaller, the legs, tarsi, 

 and antennae much stouter, and the punctation of the thorax more 

 remote. 



I found three examples near Whangarei Heads.
