OF NEW ZEALAND. 541 



smooth median stria, impressed with longitudinal wrinkles, and a single 

 slightly projecting lateral rib. Thorax as in the male. Elytra with 

 deep grooves, with sunken dots, often indistinct by confluence ; the 

 interstices hardly convex, sparsely and finely punctate, except the 

 second, fourth, and sixth, which appear usually to be smooth ; posterior 

 slope offering two interstices, grooves, and a large oblique depression ; 

 these grooves are rugose, the intervals tubercular, bristly, those nearest 

 the outside the longest, the third a little more convex and elevated at 

 the extremity, the fifth stronger and terminated by a large and acute 

 projection situated on the lateral margin of the depression, which is 

 flat, sub-circular in form, the surface finely rugose, with some tubercles 

 arranged along the suture. Abdomen transversely convex, more strongly 

 and more closely punctate than in the $ .

957. P. apicaliS, White; Voy. Er. Terr., Ins., p. 18. Deep 

 brown, basal joint of antennae, metathorax and femora yellow ; head 

 sloping, a slight keel on the vertex in the middle ; thorax very smooth, 

 shining, the side with a depression for the fore leg, with a notch hardly 

 visible from above ; elytra rather deeply channelled, sloping behind, 

 with a strong tooth-like projection on each near the end closer to the 

 margin than the suture ; anterior tibia with oblique grooves which 

 terminate on the outside in teeth. 



Length, 2f lines. 

 Kauri wood. 



NOTE. I found this species at Tairua, but I think Mr. White had 

 been misinformed as to the tree in which it exists. 



958. P. caviceps, n.s. Body cylindrical, convex, castaneous. 

 Head sparsely punctate, greatly concave in front, rather shining, with a 

 slight abbreviated carina on the vertex extending to the frontal depres- 

 sion. Thorax cylindric, of the same width as the head ; the base, which 

 is not closely applied to the elytra, is slightly produced in the middle, 

 and sinuated towards the sides, these are incurved and modified to admit 

 of the free motion of the front femora, the hind part of the excision is 

 obtusely pointed, and from thence they are obliquely rounded ; the sur- 

 face is nearly plane, and exhibits a cordiform space behind formed by a 

 dense punctation, this is longitudinally divided by an impressed dorsal 

 line. The elytra are twice the length of, and of the same width as, the 

 prothorax ; there is a rather deep scutellar emargination, their sides are 

 almost parallel, a little wider behind than elsewhere, and are rounded 

 posteriorly, there is an excision just before the apex so that the apices 

 seem to be produced ; each elytron has eight indistinctly punctured striae, 

 which hardly attain the base, the suture and middle of each are a little 

 depressed, the basal region is perceptibly granulated, and the insterstices 

 near the sides and apex are more or less punctulated ; they are of a 

 dark reddish-chestnut colour in front, and pitchy behind.
