482 COLEOPTERA 



bus impresso ; antennis subferrugineis, scapo brevi, funiculo 1 articulis 

 quinque ultimis valde transversis ; clava ampla, pubescente ; prothorace 

 transverse, postice sensim latiore, basi bisinuato, in medio carinato ; 

 elytris striato-punctatts, interstitiis late planatis, apice rotundatis ; tibiis 

 sat elongatis, intermediis extus in medio dente tenuato armatis.

Tairua (Captain Broun). 



This very distinct species has much the habit and colouration of our 

 Hylesinus fraxini (a. Scolytid)^ but it is considerably larger. 



855. P. tlbialis, n.s. Pitchy-brown, antennae and tarsi* ferru- 

 ginous. The head bears round, the rostrum elongate, punctures; 

 between the eyes there is a rounded fovea. The mandibles are strong 

 and prominent, and meet in front with a straight suture. The eyes are 

 somewhat truncated anteriorly, rather large, slightly convex. The scrobes 

 are deep and broad, and directed backwards to the lower part of, but 

 not below, the eye. The thorax at its base is of the same width as the 

 elytra, and is nearly truncate ; the sides are rounded and narrowed 

 anteriorly, and rather abruptly, and considerably, contracted in front ; 

 its surface is distinctly punctured throughout. The elytra are convex, 

 their sides rather straight and abruptly declivous, narrowed gradually 

 behind, apices rounded, pygidium covered ; their sculpture consists of 

 seven distinct striae, in which the punctation is rather coarse ; the 

 interstices are moderately elevated, rather broad, are tolerably smooth 

 behind, but rugose in front, a line along the base being finely granulated. 



The femora though incrassated are not dentate, and only slightly 

 grooved ; the anterior tibia is nearly straight inwardly, moderately curved 

 and dilated externally, and terminates in a strongly curved calcar, 

 behind which the tarsus is inserted ; the other two pairs are strongly 

 curved, and dilated externally, and besides that outward curve, they are 

 bent from front to rear, so as to give them a somewhat twisted appear- 

 ance ; the tarsi are rather longer than in Psepholax, are almost destitute 

 of clothing, and have the lobes of the penultimate joint narrower. The 

 body is nearly nude, but there are a few griseous setse on the thorax, 

 and the legs are moderately pilose. 



Length, 4^ lines. 



I found a specimen of this species at Auckland some years ago. 

 Though I have referred it to Psepholax^ it cannot remain permanently 

 attached to that genus, and will, I think, form the type of a new one. in 

 close proximity to it.

Antenna moderate, first joint not reaching to the eye, very slightly 

 bent and gradually thickened to the end ; funiculus seven-jointed, first 

 and second joints longish, the second longer than the first, and consider- 

 ably thickened at the end, the last five joints somewhat cup-shaped, 

 gradually wider to the end, the club being hardly distinct from the
