Colcoptera from New Zealand. 79 



narrowed in front as it is beliind ; the central o^voove does not 

 reach the apex, and it is a little expanded in the middle; 

 near tlie base a transverse impression connects the centio- 

 basal angular fovea and the large one at each side. Elytra 

 oblong, slightly narrowed towards the shoulders ; the sutural 

 and intrahumeral impressions are well-marked ; close to the 

 base there are two punctiform marks. Hind body not longer 

 than the elytra, the basal three segments marginated and 

 nearly equal, the first depressed across the base, fourth de- 

 flexed and as long as the third, lifth simple. Legs moderately 

 elongate, not thick, the anterior femora most robust. 



Antennae slender, the basal two joints nearly equal as to 

 length ; third nearly as long as the second, but much more 

 slender ; 4 to 7 differ but little ; eighth rather smaller ; ninth 

 and tenth larger than the preceding ones, scarcely trans- 

 versal ; eleventh large, acuminate. 



Underside rufescent. Head simple, studded with erect 

 setge, which are thickened at the extremity ; the frontal por- 

 tion is short. Front and middle coxce contiguous, the poste- 

 rior nearly so at the base. Segments 2 to 4 subequal ; first 

 densely pubescent, covered by the femora, with a central 

 prominence between the coxee ; fifth hardly as long in the 

 middle as at the sides ; the terminal one with a fine suture, so 

 that there seems to be a supplementary segment. 



This species must be placed with No. 1700 and its allies; 

 from these it may be distinguished by the slender antennai 

 and sculpture. The pubescence is short and slender. 



Length I, breadth nearly § line. 



Invercargill. One, received from Mr. A. Philpott, March 

 1894. 



Euplectus arohaensis, sp. n. 



Subdepressed^ not narrow, moderately nitid ; red, the legs 

 and antenna3 paler ; tarsi and palpi yellowish ; pubescence 

 yellow, rather dense, short, and decumbent; there are also 

 many erect, elongate, slender seta^. 



Head large, widest behind, apparently impunctate; the 

 large interocular foveas unite with the frontal depression ; the 

 tubercles are small and widely separated, and the frontal 

 channel is bounded by the slightly raised front edge of the 

 forehead. Eyes rather small. Thorax hardly longer than 

 broad, the middle widest, the apex scarcely as wide as the 

 base ; it is impunctate ; in front of the base there is an angu- 

 late impression which unites with the fovea at each side; 

 there is no central longitudinal groove. Elytra hardly longer 

 than broad, narrowed towards the shoulders ; the sutural and
