suture and adjoining interstice, as well as the cariniforin 4th and 6th, 

 do not quite reach the basal margin. Antennae with the 11th joint 

 indistinct. 



Underside rufescent, shining, with rather coarse punctures, each with 

 a minute seta ; 5th ventral segment slightly concave, and almost as 

 coarsely punctate as the others. 



A careful scrutiny of the base of the elytra will be an aid in dis- 

 crimination. The anterior angles of the thorax are more acute than 

 those of 1949, the lateral margins are thicker throughout, and the dis- 

 coidal impressions are not at all sharply bordered. 



Length, 3h mm. ; breadth, 14; mm. 



Greymouth. Unique. Found by Mr. J. H. Lewis. 



Obs. — From the same source specimens were received of Sharp's 

 P. longulus. If I am right as regards identification, the following notes 

 will be useful to other students : Presternum opaque and closely punc- 

 tate; metasternum glossy, more coarsely but rather distantly punctured, 

 medially sulcate behind; terminal ventral segment depressed or slightly 

 concave, its frontal margin incurved, thus leaving a transverse depres- 

 sion at the apex of the penultimate. Size, nearly 4 mm. by li mm.

Elongate, almost glabrous, slightly nitid ; black, legs and antennae 

 rufescent. 



Head moderately finely, yet distinctly, but not very closely punctate. 

 Eyes very prominent. Thorax of about equal length and breadth, apex 

 subtruncate, its sides nearly straight from the rectangular anterior angles 

 to beyond the middle, slightly narrowed behind, basal angles rectangular ; 

 it is more coarsely punctured than the head, more closely near the sides 

 than on the middle, much more finely in front; there is a slight elongate 

 central fovea with smooth lateral borders. Scutellum sparsely punctate. 

 Elytra with rounded shoulders, broader than thorax at the base, thrice 

 its length, their sides gently rounded; on each elytron there are 6 dorsal 

 finely and rather distantly punctured but not always well-defined striae ; 

 the suture, as well as the 3rd and 5th interstices, are cariniform behind ; 

 the suture is finely punctate, as are also the plane intervals between the 

 adjacent striae. 



Antennae with slender pubescence, basal 2 joints normal, both thick; 

 3rd evidently longer than broad; joints 4-8 about equal, as long as they 

 are broad; 9th rather longer than its predecessor; 10th quite as long 

 as broad, narrowed towards its base, at its apex not double the width of 

 the 9th; 11th rotundate, rather narrower than the 10th. 



The club is usually composed of the abruptly enlarged transversal 

 10th and 11th joints, whereas in this species the 10th is subtriangular 

 and, at its base, no broader than the extremity of the 9th, and the 11th, 

 though rounded, is as long as broad. 



The insect is rather more slender than previously recorded species, 

 and has more convex and prominent eyes. The few ash-coloured slender 

 setae are hardly perceptible. 



Length, 3h mm. ; breadth, 1 £ mm.
