OF NEW ZEALAND. 997 



Head nearly smooth, with the usual impressions ; labrum sub- 

 truncate, rather short ; eyes moderately prominent. Thorax rather 

 short, about one-third broader than long, its sides almost regularly 

 rounded, rather narrower behind than in front, posterior angles 

 quite obtuse, apex subtruneate, base incurved ; dorsal groove not 

 deep, not reaching the base or apex ; basal fossae rather large, 

 placed nearer to the sides than to the middle ; it is slightly convex, 

 and not smooth, there being a round impression in front of each of 

 the fossae, besides some others, all shallow however, on the disc. 

 Scuiellinn striate at base. Elytra with moderately-rounded sides, 

 rather strongly sinuated apically, shoulders without projections ; 

 the striae irregular, not deep, more or less interrupted behind the 

 middle, the surface there indistinctly waved,- the punctuation ill- 

 defined, never coarse, sometimes narrow and elongate, in the female 

 more regular and distinct. Legs robust, all the femora inflated, the 

 posterior angulate below ; tibias thick ; front tarsi strongly dilated. 

 Abdomen with four punctures on the apical segment. 



Thoracic setai in my three males rubbed off; but in a headless 

 female, the only one I have seen, I can detect four on one side. 



(? . Length, 6 ; breadth, If lines. 



Castle Hill, Canterbury. Mr. J. D. Enys collected the three 

 males and one female. 



1790. P. egmontensiSj "••5- Suhparallcl, slightly convex; 

 glossy-black ; antennae, tarsi, and palpi rufo-piceous, tips of the ter- 

 minal joints of these last ferrugineous. 



A careful comparison with the male of No; 1335 (P. crihralis) 

 results in the following differences being observed : — 



P. egmontcnsis is smaller, the trophii and tarsi are much darker ; 

 the legs are shorter, notably the posterior ; intermediate tihice 

 obtusely prominent or swollen along the lower half of their front or 

 inner face (as is also the case in No. 1335), but less denticulate or 

 asperate, only feebly indeed, and with more spiniform setae on the 

 external face. Thorax more quadrate (2^ lines broad, 2 long ; 

 No. 1335 measures 2f x 2|- lines), slightly rounded near the front, 

 the sides beyond very gradually narrowed and slightly curvate, and 

 a little sinuate towards the basal angles, which are quite rectangular, 

 and sometimes just perceptibly projecting. In No. 1335 the sides 

 are gently but regularly rounded, so that there is no apparent sinua- 

 tion behind. The superficial sculpture is similar in both, on the 

 head as w^ell as the thorax, the rugosities or aciculate marks being 

 distinct or obsolete, but some slight notches can be seen before the 

 posterior angles on the margins which are absent in No. 1335. 

 Elytra shorter (4i x 2| ; in No. 1335, b\ x 3| lines), less narrowed 

 towards the prominent shoulders ; there is a short scutellar stria ; 

 the seven dorsal striaB are more deeply impressed, and, when inter- 

 rupted, as most of them are, consist of about double the number of 

 depressions or punctures ; the .sutural three reach the apex, all reach 

 the base ; the third, fifth, and seventh interstices ai'e very slightly 

 wider than the others, the broad lateral one between the seventh
