Coleoptera from Neio Zealand. 169 



which seems to be limited in front by a small obtuse elevation ; 

 antennal tubercles well-developed, with an obvious channel 

 between them ; the sides, behind the eyes, are coarsely ciliate. 

 Thorax rather longer than broad, constricted and depressed in 

 front, widest and most convex near the middle, just before the 

 base there is a curved transverse impression ; its clothing is 

 rather scanty on the disk but forms a sort of fringe along the 

 sides. Elytra as long as broad, a good deal narrowed towards 

 the base, apex truncate ; the sutural sti-iaj are well marked 

 and become deeper near the base, inside each shoulder there 

 is a deep elongate impression; they bear fine decumbent hairs 

 and long, erect, slender setge. Hind body as long as the 

 wing-cases, gradually narrowed backwards, its three basal 

 segments of about equal length, with distinct margins, the 

 other two deflexed, its pubescence elongate. Legs elongate ; 

 femora slender near the base, somewhat clavate near the 

 middle : front tihice nearly straight, with dense fulvous pu- 

 bescence on the inside towards the extremity; the intermediate 

 slightly arcuate below the middle, densely pubescent near the 

 apex, and finely ciliate externally ; the posterior also fringed, 

 straight as far as the middle, and, on the inner face, below 

 the middle, armed with a conspicuous spiniform process, they 

 are a little thickened and curved there. 



Antennce long and stout ; basal joint cylindric, thicker, and, 

 on the outside, nearly twice the length of the next one ; joints 

 3 to 6 evidently longer than broad, the fourth slightly shorter 

 than the contiguous ones ; seventh quadrate ; eighth trans- 

 verse, of the same width as the preceding one ; ninth a little 

 longer than broad; tenth quadrate, but, like the ninth, slightly 

 narrowed towards the base, both these joints thicker than the 

 eighth ; eleventh large, oblong-oval, obtuse, with a fovea 

 underneath ; the last three joints are more or less distinctly 

 asperate. 



Underside chestnut-red, with depressed yellow pubescence. 

 Head with a basal depression. Metasternum depressed along 

 the middle, the sides of the cavity gradually, but considerably, 

 raised anteriorly, and, just behind the middle coxeb, ending in 

 a thick spiniform protuberant process. Abdornen much nar- 

 rowed posteriorly, rather flat along the middle, with deep 

 sutures, the fifth segment smooth and transversely impressed 

 in the middle, sixth conical, deeply depressed in the centre and 

 carinate behind.
