Broun. — Revision of the Xetv Zealand Cossonid;^'. 159 



frontal limitation of the occiput is even more abruptly defined, nud the 

 thorax is broader and more oviform. 



Touropsis punctatus, Broun. 925. Man. N.Z. Coleopt,, p. 518. 



Shining, castaneo-rufous, antenna" and tarsi fulvescent. 



Kostrum convex, finely and not closely punctured, nearly smooth along 

 the middle. Head distinctly but not closely punctured as far as the back 

 of the eyes ; this portion apparently on a higher level than the front of the 

 smooth occiput. Thorax about as broad as it is long, widest behind the 

 middle, Avell rounded there, nuuli narrowed and deeply constricted in front, 

 hardly perceptibly flattened above, the central linear space nearlv smooth, 

 its punctuation distinct but not coarse or close, finer but not smooth in 

 front, having minute coriaceous sculpture there. Elytra punctate-striate, the 

 punctures somewhat transversely angular, the suture and interstices with 

 fine serial punctures. 



<? . Length, nearly IJ lines ; breadth, nearly | line. 



Tairua, Auckland. Unique. 



Euophryum, gen. nov. 



Body transversely convex, subcyliudric. narrowed anteriorly. Rostrum 

 more than half the length of thorax, only moderately broad, somewhat 

 abruptly contracted near its base, so that the scrobes seem deep and wide ; 

 the sides, underneath, are swollen for the greater part of their length, and the 

 central carina extends from the mentum and becomes thicker near the 

 eyes. In the female the rostrum is more slender, and, behind the contrac- 

 tion, is a little expanded, so as to become as broad as the front of the eyes. 

 Scape inserted just behind the middle, short, stout, and incrassate towards 

 the extremity ; it only reaches the front of the eye. Funiculus longer 

 than the scape, 2nd joint slightly longer than 3rd, 2-5 gradually thickened, 

 5th transverse. Club ovate, of moderate bulk. Eyes subrotundate, trans- 

 verse rather than longitudinal, more prominent behind than in front, the 

 smooth occiput being somewhat narrowed anteriorly. Thorax nearly twice 

 as long as broad, ovate-triangular. Scutellum small, but distinct. Elytra 

 cylindric, sHghtly narrower than thorax, individually strongly rounded at 

 apex, causing a sutural gap there, their margins posteriorly expanded or 

 incrassate. Tarsi narrow, penultimate joint narrow, excavate but not 

 lobate. 



The buccal cavity is well marked, and there is a minute dentiform pro- 

 jection of the mentum within it. The anterior coxa? are more approximated 

 than in Pentarthmm, with a fine curvate suture between them. The epi- 

 pleune are slightly thickened behind, and the dilatation seen on the upper 

 surface is quite evident on the lower also, but distinct from the epipleura 

 itself. 



The characters which distinguish this genus from I'cnlarthrum are the 

 obviously basally contracted rostrum, deep broad scrobes, short scape, in- 

 crassate elytral margins, strongly singly rounded apices, and sutural notch, 

 these last two being quite exceptional features amongst the Cossonidcr. 

 The underside also differs. The more parallel outline and coarser sculpture 

 will also aid in the identification of the species now detached from Pen- 

 tarthrvm. 



In the female the antenna:> are inserteci midway between the middle of 

 the rostrum and the eves.
