OF NEW ZEALAND. 1139 



Antennce with stout first and second joints ; third joint also 

 stout, but articulated to the second joint by an extremely slender 

 base ; fourth joint larger than those following, which are very 

 minute, the ninth and tenth being, however, broader than the 

 others, and strongly transverse ; terminal joint rather shorty and 

 broad, nearly as long as the two preceding together. Thorax twice 

 as broad as long, base very closely connected with the elytra. 

 Scutellum triangular, rather large. Elytra almost without sculp- 

 ture, closely embracing the hind-body, their hind margin obliquely 

 subtruncate, a little incrassate, and minutely directed upwards. 



This very obscure but very interesting little beetle was detected 

 at Greymouth by Mr. Helms some years ago, but only in a single 

 example, which I sent back to him after examination, and I have 

 now received two other examples from him. 



Cyphanus (Gen., p. 308). 



2020. C. dubius, n.s. Suboblong, slightly glossy, densely 

 clothed with fine yellowish hairs ; castaneous, the thorax and basal 

 region of the elytra more or less rufescent, legs, antennae, and lower 

 surface chestnut-red. 



Head large, moderately coarsely but not deeply punctured. 

 Antenna elongate, second joint short, third scarcely half as long as 

 fourth. Prothorax strongly transverse, base and apex sinuated 

 towards the sides, these latter explanate and but little curved ; its 

 angles obtuse ; its punctation is finer than that of the head. Elytra 

 subcostate, densely, distinctly, and somewhat rugosely punctured. 



This species is rather dark in colour and bears conspicuous 

 pubescence. The prosternal process, though hastate, is not acutely 

 prolonged behind. The intermediate segments of the abdomen have 

 distinctly membranous sutures. 



Length, 3J ; breadth, If lines. 



Found on the Waitakerei Range and in the vicinity of Howick. 



2021. C. SCaber, n.s. Oblong, subovate ; dark rufo-castaneous, 

 head dark-red, legs red, tarsi and antennae testaceous-red; not 

 shining, covered with yellow hairs, these are most conspicuous 

 behind, some of those on the thorax are very fine and silky, others 

 seemed disposed to form patches. 



Head broad, much dilated behind the eyes, its punctation fine 

 and dense ; labrum much exposed, deeply emarginated. Antennce 

 moderately elongate, rather slender, third joint almost as long as 

 fourth. Thorax transverse, its angles obtuse, sides a little curved ; 

 the disc transversely convex, with a gradual slope outwards so that 

 the sides do not appear explanate, its punctation fine but dense. 

 Elytra elongate, not broader than thorax at base, widest in line with 

 hind thighs, from thence a good deal rounded apically ; densely and 

 finely punctured, slightly uneven, there being, on each, three or four 

 indistinct basal striae or impressions. Legs normal, tibial spurs well 

 developed.
