narrowed backwards, and do not always cover the pygidium entirely. Front 

 coxae only moderately separated. Metasternum evidently medially sulcate. 

 nearly as long as tlie abdomen. Basal ventral segment truncate behind, 

 very distinctly separated from and on a higher level than the shorter 2nd, 

 3rd and 4th each not much shorter than the 2nd, all except the basal one 

 on the same level as the epipleurai. Legs finely setose, rather short. Tibise 

 somewhat laterally compressed ; the anterior, at the inner angle, with a 

 stout spur directed outwards, the external angle bidentate ; the 2 hind 

 pairs strongly curvedly expanded inwardly, and externally terminating 

 in a broad lamelliform process which is minutely denticulate at the ex- 

 tremity, the inner ends with a small spur. Tarsi sparsely rubescent, basal 

 joint about as long as the terminal one, which, in the posterior pair par- 

 ticularly, is rather slender ; claws rather small but distinct ; 3rd tarsal 

 joint indistinctly lobed. 



This curious genus, owing to the hylastideous structure of the tibiae, 

 is placed last on our list, near Inosomus, from which, however, it is essentially 

 different. Its single exponent lives in kauri timber {Agathis australis), 

 and varies considerably in bulk and coloration. 



Xenocnema spinipes, Wollaston. 953. Man. N.Z. Coleopt., p. 537. 

 (Plate XVI, fig. 15). 



Piceo-rufous or piceous, moderately nitid. 



Rostrum closely and rather finely longitudinally rugose and punctate. 

 Head finely and distantly punctured. Thorax slightly longer than broad, 

 its sides nearly straight, rather closely and finely punctured, the apex and 

 a linear median space nearly smooth. Elytra with deep, regular, closely 

 punctured strire ; interstices obtusely costiform, each costa with a finely 

 punctured definite groove along the middle, so that the interstices appear 

 duplicated. 



Underside shining, nearly glabrous, almost regularly, moderately finely, 

 relatively punctured, the abdomen more coarsely, the terminal segment, 

 however, and the mesosternum behind very closely and finely. 



Female. — Rostrum oblong, the dense punctuation of the head ceasing 

 abruptly behind the eyes, occiput smooth and shining, thorax gradually 

 narrowed anteriorly.

The description has been taken from specimens in my own collection. 

 The maximum measurements are given. Wollaston's specimen was only 

 half as large, If lines.

Body small, subdepressed, elongate but not parallel, finely setigerous, 

 shining, quite red. Lif^fe-' 



Head and rostrum combined as long as the thorax. Rostrum in front 

 as broad as the occiput, subpterygiate there, incurved at the middle, arched ; 

 at its base on a lower level than the head. Scrobes subapical, quite open 

 and visible above. Head globose, with a frontal fovea. Scape flexuous, 

 finely setose, elongate and stout, gradually incrassate, inserted near the 

 apex, and attaining the front of the thorax. Funiculus also very long, 

 laxly articulated, basal joint large, joints 2-7 gradually decrease in length, 

 2nd longer than broad, only slightly longer than 3rd. Club oblong-oval, 

 indistinctly annulate. Thorax elongate, oviform, without any frontal 

 stricture, its base rounded, the disc nearly flat. Elytra longer than the
