510 COLEOPTERA 



occiput, however, is much more finely sculptured, and indistinctly con- 

 stricted. Antenna finely pubescent. 



In the male the rostrum is stout, parallel and rather convex, and has 

 the antennal club elongate and not very abruptly marked off; in the 

 female the beak is more slender, a little depressed, and much more 

 finely sculptured. In both sexes the antennal insertion is behind the 

 middle. 



Length, 2j lines. 



I found two males and one female at Parua, near Whangarei Har- 

 bour. 



907. P. brunneum, n.s. The form of this insect is very similar 

 to that of the female P. zealandicum, and might be readily mistaken for 

 it, but it is smaller, has a larger and more distinctly triangular or elon- 

 gate-conical thorax, which is more closely adapted to the elytra, and 

 very gradually narrowed to the width of the head, and with a very slight 

 apical constriction ; it is rather convex, not at all depressed on the 

 dorsum, and is somewhat distantly and distinctly punctured. Scutellum 

 transverse, very small. The elytra are cylindrical, very slightly wider 

 than the thorax, with punctured striae, and flattened rugulose interstices; 

 the sculpture of the apical portion is more prominent and confused, the 

 third and marginal striae being elevated and confluent. The thighs are 

 strongly inflated, and the tibiae rather straight. 



The rostrum is shining, finely punctulated, of the same form as that 

 of the female P. zealandicum. The eyes are somewhat flattened and not 

 prominent. 



The insect is of a pale brown or chestnut colour ; the thorax and 

 rostrum are redder than the elytra, and it is more or less clothed with 

 fine pallid setulse. 



Length, if line. 



I found one specimen only at Tairua. 



908. P. rufum, n.s. Body dark red, sub-cylindrical. The rostrum 

 is similar to that of P. zealandicum, but not so much depressed, dis- 

 tinctly punctured, and with the antennal insertion slightly behind its 

 middle part. 



The eyes are moderately prominent, with a very distinct transverse 

 impression behind them. Antenna stout, the scape short, the club 

 rather elongate and not well limited, the joints of the funiculus being 

 gradually thickened. Prothorax rather large, slightly convex, triangu- 

 larly-ovate, with obtuse posterior angles, it is a little dilated and rounded 

 behind the middle, and narrowed anteriorly, with a distinct frontal con- 

 striction; its surface is rather unevenly punctured, the punctation 

 becoming more remote near the middle than at the sides, and much 

 finer near the apex. Scutellum transverse. 



The elytra are cylindrical, slightly narrower than the thorax, with 

 parallel sides, and individually rounded apices ; they are very distinctly 

 striated, the striae are coarsely and closely punctured, the interstices are 

 rugulose, and their apical portion being somewhat abbreviated, leaves a 

 broad groove inside the explanated apical margins.
