Urad moderately coarsely, closely, and more or less rujiosely |»iiii( tured. 

 Tlionix a third hroader than lonfj;, the sides distinctly marj^ined, curvedly 

 narrowed near the front ; anterior angles a little deflexed and nearly rect- 

 ani'ular. the posterior directed l)ackwards so as to clasp the shoulders ; 

 disc distinctly, moderately closely, hut le.ss coarsely punctured than the 

 head, more titielv towards the base, which at the middl<' is more convex 

 than it is towards the sides ; near each side there is a well-marked smooth 

 -ri'oove. with sharp outer margins, which becomes less distinct towards the 

 front. Scut cI I urn smooth, (piadrate, not at all transverse. Ehjtra of the 

 same width as the thorax, quite twice its length, narrowed posteriorly ; they 

 are moderately and irregularly punctured ; the striae are el'faced on the 

 middle, and onlv moderately impressed behind and near the sides, but 

 some are deep at the base, only 1 or 2. however, penetrate its thick margin. 



Lcqs robust, bearing long erect hairs ; the tiliiae with tine yellow 

 pubescence along the inner face. The hind claw of each of the anterior 

 tarsi is shorter than tlie other in one specimen. 



Und^^rsidc subopaque. Prosternum rather finely punctured'. Ahdonicn 

 covered with decumbent pale pubescence, very indistinctly punctured, 

 the terminal segment, however, almost coarsely punctured and subgranu- 

 late, with longer hairs, and medially elevated at the extremity. 



The elytral striae are less distinct than in A. agrestis (440) ; the hei;d 

 is more coarsely and rugosely punctured, the thorax rather more finely, 

 and it lacks the finer decuml)ent pubescence visilile on that species. The 

 scutellum is not transverse. 



Length. 2 lines ; lueadth, | line. 



Waimarino. January, 1909. A pair found amongst leaves, on tin' 

 ground. 



Obs. — When drawing up the above description 1 carefully examined the 

 antennae of six specimens found at Tairua. Mount Pirongia. Wellington, 

 and Te Aroha ; in all these the antennae are 11 -articulate, as stated in 

 the generic diagnosis, p. 1107, Man. N.Z. Coleopt. In Dr. Sharp's Protn- 

 Darnus these organs are described as 10-jointed. No specimens have been 

 st-nt to tn«' ;)s vet from Greymouth, the recorded habitat of his species. 



( Troup Hydrophiliu.ve. 

 3032. Stygnohydrus femoralis sp. nov. Gen.. Man. N.Z. Coleopt.. p. 13o<i. 



Oval, very convex, glabrous, shining ; piceo-niger. slightly bronzed : 

 the sides of thorax, the suture, and apical portion of elytra somewhai 

 rufescent; legs and mandibles dark red: ])alpi. tarsi, and antennae ihi 

 vescent : club dull and infuscate. 



Head large, subquadrate, its sides a little rounded, finely yet distinctly 

 but not closely punctured. Lahrum very transverse, distimtly punctaie. 

 feel>ly emarginated medially, marked off from the forehead by a deep furrow. 

 Eve.s entire, very finely faceted. Mandiblra very broad, but slender a)i(l 

 acute at the extremity. Thnrax transverse, its base sul)truncate and very 

 accurately fitted to the elytra, in front n\edially rounded, and sinuated 

 towards the slightly prominent but obtu.se angles ; the sides feebly curved 

 and margi hated, posterior angles rounded, but just in front of them the 

 sides are rather broader than the base of the elytra ; its punctation rather 

 shallow and di.stant. Srntrlhnn triangular, finely punctate. Ehjtra irregu- 

 larly, rather finely, but not do.sely punctured, some punctures rather larger
