Thorax with four tactile setae at each side. 



Thorax with two fossaj at each side, at the base. 



ScuteUum striate at base. 



Abdomen with four setae on apical ventral segment. 



Length, 9 lines ; breadth, 2| lines. 



Boatman's, near Reefton. Air. A. T. Cavell is the discoverer. 



1792. P. insidiosus, "•■^■- Eloiujate, subparallel, slightly con- 

 vex ; glossy-black ; tarsi nigro-piceous. 



Allied to P. catcnulatus. The lahrum not deeply emarginate as 

 it is in that species. Head more constricted behind the eyes, not 

 wrinkled. Thorax of similar proportions, one-eighth broader than 

 long ; more narrowed behind than in front, only a little curvate 

 laterally, without any sinuation behind ; base medially incurved, 

 slightly rounded towards the angles, so that these are ill-defined ; 

 lateral margins and channels narrower than in No. 1335 ; disc 

 obsoletely striate ; dorsal groove distinct, not quite reaching the 

 front margin, expanded near the extremities ; basal fossae lai'ge, 

 about midway from the sides and middle. Sciitellum deeply striate 

 at base. Elytra nearly twice as long as broad, shoulders only 

 slightly prominent, their sides a little rounded, the posterior narrow- 

 ing rather abrupt, more so than in No. 1336 ; they are moderately 

 punctate -striate, with scutellar striae; interstices not wrinkled 

 transversely, the third, fourth, and sixth with two or three puncti- 

 form impressions ; these are not, however, regular ; the sculpture 

 appears a little irregular, and becomes more confused behind, where 

 the punctuation is obsolete. Legs rather short and thick ; posterior 

 femora subangulate below. Underside shining ; the head and pro- 

 sternum without the f:ine rugose sculpture of P. cateiiulatus. 

 Ahdoincn with two punctures on each side of the hind n:argin. 

 Thorax with fine seta on each side, one on the basal angle, the 

 others about equidistant from each other and extending from the 

 front to just behind the middle. 



S . Length, 7-7f ; breadth, 2-2^ lines. 



Invercargill. ^Nlr. T. Chalmers ; two males. 



1793. P. inconstans, "•«• Elongate, subparallel, slightly con- 

 vex, glossy-black, femora rufescent. 



This species is very much like P. insidiosus ; the tliiglis are red; 

 the thorax is exactly as long as broad, with four lateral setae on 

 each side, and there is an evident curved impression near the front ; 

 sciitellum not striate, yet not quite smooth; elytra with finely punc- 

 tured striae, not always regular, the third interstice on one elytron, 

 and the sixth on the other, with slight catenulate sculpture ; lahrum 

 distinctly emarginate ; abdomen with four punctures along the pos- 

 terior margin. 



S . Length, 7 ; breadth, 2^ lines. 



luvercargill. ]ilr. Chalmer ; one male.
