COLEOPTERA 



Group-COSSONID^l. 



Pentarthrum (p. 5 8 )- 



1626. P. angUStum, n.s. Narrow, almost parallel, widest 

 behind middle of thorax, sub-depressed, but little shining, dark-red ; 

 apex of thorax, head between the eyes, and extremity of hind-body 

 darkest ; tarsi and antennal club pale-red ; sparingly clothed with 

 slender, inconspicuous greyish hairs, those on the elytra much 

 shorter than those on the thorax ; legs more distinctly clothed. 



Rostrum shorter than thorax, a little (but widely) contracted 

 behind the middle, indistinctly striate, punctate ; the whole surface 

 finely but densely sculptured, and therefore appearing rather rough. 

 Antenna implanted before the middle, scape minutely sculptured ; 

 second joint of funiculus longer than third ; club ovate. Head 

 rather rough between the eyes, its sculpture seeming to be rugose 

 and elevated, slightly dilated laterally behind the eyes ; these latter 

 moderate ; neck not smooth. Prothorax longer than broad, widest 

 near the base, narrowed and constricted anteriorly, posterior angles 

 rounded ; disc nearly flat, middle of apex nearly smooth, moderately 

 punctured, fewer punctures on the dorsum than elsewhere, some- 

 times with a smooth median line ; interstices densely and minutely 

 sculptured. Scutellum small. Elytra nearly twice the length of 

 thorax, not quite so broad, almost parallel, slightly convex, apices 

 not explanate, not deeply (almost crenate) punctate-striate, inter- 

 stices finely rugose. Legs moderately long, densely sculptured, tibiae 

 not much dilated, their hooks stout ; penultimate joint of tarsi 

 bilobed. 



$ . A trifle more depressed, rather longer (if lines), rostrum a 

 little dilated where the antennae are inserted (middle), narrower 

 behind, moderately punctured ; densely, finely sculptured ; longer 

 than in the same sex of P. zealandicum ; neck not smooth. 



Of the same colour as No. 908, narrower, less convex, &c. 

 $ . Length, if lines ; breadth, f . 



One pair. The female taken off a Veronica buxifolia on Mount 

 Maungatua, by Mr. S. W. Fulton ; the male found near Dunedin, 

 by Mr. T. Chalmer. 



1627. P. proximum, n.s. Bed, head darkest, tarsi and an- 

 tennal club fulvo-rufous ; thorax with a few fine yellow hairs, elytra 

 with inconspicuous, slender, greyish-yellow hairs ; slightly glossy, 

 moderately convex. 



Rostrum stout, parallel, somewhat depressed, sub-canaliculate, 

 rugose-punctate, the punctation coarser on the head, neck with a 

 few punctures ; eyes prominent. Antenna mediately inserted, 

 second joint of funiculus slightly longer than third; club ovate, 

 with fine yellow pubescence. Prothorax ovate-triangular, con- 

 stricted in front, hind angles obliquely rounded, moderately punc- 

 tured. Scutellum smooth. Elytra as broad as thorax, not explanate 

 behind, base slightly bi-arcuate ; punctate-striate, interstices a little 

 convex, distantly and finely punctured. Legs normal, femora 

 densely and finely sculptured, tibiae punctate.
