entire absence of tubercular elevations, except near the apex, 

 separate it from B. lohata and B. scita, independently of the glossy 

 and nearly nude aspect of the hind-body. 



B. rugosa, besides other disparities, may be distinguished from 

 its three congeners by the presence of several irregular cavities on 

 the elytra.

Mr. T. Chalmer detected a specimen near Dunedin.

Pycnomerus (p. 208). 



1598. P. carinellus, n.s. Elongate, sub-parallel, moderately 

 shining, bearing exceedingly minute greyish hairs, pitchy-black ; 

 legs and antennae pitchy-red. 



Head with two deep frontal expressions, each separated from the 

 side by an elevated space ; it is coarsely (comparatively) punctated ; 

 eyes coarsely facetted. AntenncB 11 -articulate, the eleventh joint 

 but little smaller than tenth, densely pubescent and appearing 

 punctate. Protliorax convex, slightly narrowed towards the base, 

 closely and coarsely punctured all over and without other distinct 

 sculpture. Elytra elongate-oblong-oval, base a little arcuate-emar- 

 ginate, sides but little curved, strongly punctate-striate, apex 

 rufescent ; the interstices narrow and convex, second, third, and 

 fifth insulated. 



The thorax and elytra less contracted towards their bases than 

 in P. ellipticus, the elytral suture plane instead of convex, the third 

 interstices elevated in front and united at the base by a short carina, 

 the scutellar region consequently seeming more depressed.

I found one example at Woodhill (Kaipara Eailway). 



1599- P. C^CUSj 'i-s. Sub-parallel, elongate, moderately con- 

 vex, shining, dark-red, sparingly clothed with some minute greyish 

 hairs. 



Head punctate, the frontal cavities prolonged to its back part, 

 lateral margins raised ; eyes obsolete. Antenna stout, the eleventh 

 joint as broad as tenth, punctate and pubescent ; though the suture 

 can be detected, the two joints seem entire. Protliorax longer than 

 broad, slightly narrowed behind, indistinctly bi-hnpressed longi- 

 tudinally, its punctation moderately fine and open, with fewer 

 punctures on the middle, its base depressed. Elytra elongate-oval, 

 base obliquely truncated towards the suture, not distinctly emar- 

 ginated, humeral angles a little porrected ; striate, the punctiform 

 impressions in the furrows elongate ; interstices rather broad, finely 

 and distantly punctured, the first and third united at the base, the 

 second and fourth insulated. 



A highly-interesting form, owing to the absence of eyes : at any 

 rate those organs cannot be detected by means of an ordinary lens. 



The thorax has fewer punctures on its surface than any other 

 New Zealand species ; the punctures of the elytral strice are un-
