OF NEW ZEALAND. 957 



Antennce elongate, a little serrate, second and third joints, together, 

 slightly shorter than fourth ; third smaller than second ; fourth 

 cylindric, being but little thickened apically, elongate. Thorax sub- 

 cylindrical, elongate, posterior angles long and divergent. Elytra 

 elongate, attenuated posteriorly, apices acutely rounded and spini- 

 form ; punctate-striate, interstices convex and punctulated distinctly 

 near the base only, the alternate ones broader and more elevated 

 than the others. $ . 



$ . Variety : Hind-body darker, with broader basal vittae and 

 the sides and a large part of the dorsum pitchy-brown ; antennae 

 more robust. 



Most nearly allied to P. elongatus, the punctation coarser, elytral 

 striae more evident, with more elevated intervals, apices more spini- 

 form, and with longer antennae, &c. The underside is testaceous, 

 with the middle of the sternum blackish. 



Length, sJ-sf lines ; breadth, f. 



Mount Egmont, Taranaki. 



I 7 2 5- P. atriceps, n.s. Opaque, pitchy-black, antennae (save 

 the fuscous basal joint) blackish, legs fuscous, knees and tarsi 

 obscure-testaceous ; front angles of thorax, two oblique median, and 

 a sub-apical, spots on each elytron testaceous, and a spot near the 

 side of the scutellum castaneous ; clothed with fine pale hairs. 



At first sight this might seem to be a variety of No. 547 (P. 

 guttatus) ; the head, however, is quite black, not at all shining, is 

 more closely, deeply, and rugosely punctured, and the edges of the 

 forehead are rather more elevated ; the thorax is less coarsely but 

 more densely punctured ; the interstices between the deep, punctate 

 striae of the elytra are decidedly more costiform and rougher, even 

 to the apices ; the sculpture is more like that seen in P. opacus, but 

 the head and thorax are still more closely and deeply punctated than 

 in that species, and the pubescence is somewhat coarser.

Oxylasma (p. 679). 



1726. O. basallS, n.s. Elongate, sub-depressed, narrowed 

 towards the extremities, slightly glossy, castaneous, base of elytra 

 testaceous. 



Antenna elongate, sub-filiform, second joint rather shorter than 

 third, and, conjointly, barely the length of the fourth. Smaller 

 than 0. tectum, the thorax not at all rugose as in that species, its 

 lateral margins less developed, anterior angles more depressed and 

 less prominent, its punctation finer but closer, and its yellow 

 villosity more conspicuous (longer and coarser) ; the elytral inter- 

 stices are much more elevated, but not rugose ; and the middle of the 

 forehead, instead of being obtusely rounded, is almost angulated. 

 The underside is more finely sculptured and clothed.
