COLTDIIDAE. 531 



4055. Vitiacus setarius sp. nov. 



Nigro-fuscous, slightly nitid, antennae, legs, and labium fusco-rufous ; 

 thinly clothed with fine, decumbent yellowish setae, wliich are most con- 

 spicuous near the sides ; lower surface rather thickly setose. 



Head indistinctly granulate, longitudinally impressed near each side. 

 Thorax slightly broader than long, the sides straight behind, a little broader 

 near the front, slightly curvedly narrowed towards the obtuse anterior 

 angles, apex widely but not deeply sinuate behind the small eyes, posterior 

 angles rectangular ; disc distinctly depressed from the apex to behind the 

 middle and partly smooth there, the coarse flattened granules become less 

 coarse and close near the broadly concave sides. Elytra oblong, subovate, 

 with obtusely rectangular shoulders, very slightly broader than base of 

 thorax, quite twice its length, a little wider near the hind thighs than else- 

 where, lateral channels narrow but quite visible nearly to the extremity ; 

 their sculpture granular or punctiform according to the point of view ; on 

 each elytron the costa near the suture extends from base to apex ; the 

 second, near the hind thigh, is short and obsolete, the third, in front of it, 

 is short and narrower ; the suture is somewhat costiform on top of the 

 declivity, which appears bi-impressed near the extremity ; from the apex, 

 just above the side margin, a granular carina extends obliquely towards 

 but distant from the thigh. 



Basal four ventral segments almost smooth, each with a slight obtuse 

 elevation between the middle and side ; fifth encircled by a sublunate 

 appendage or supplementary segment, as is the case in other species 

 described in this paper. 



More elongate than V. costatus (1937), the head without the smooth 

 basal line ; the thorax less deeply emarginate behind the eyes, discal im- 

 pression larger and deeper but not prolonged backwards as a fine stria, as 

 in 1937, its granulation coarser and more flattened ; the second elytral 

 costa obsolete ; the legs are rather thicker, and the antennal club imsym- 

 metrical. 



Length, 3| mm. ; breadth, IJ mm. 



Erua, near Waimarino. Two examj^les found amongst decaying forest- 

 leaves in January, 1909 and 1910. 



4056. Vitiacus lateralis sp. nov. 



Elongate, a little broader near the front of thorax than elsewhere, spar- 

 ingly clothed with fine fulvescent setae, slightly nitid ; dark fusco-rufous, 

 the labrum, antennae, and legs more rufescent. 



Head with indistinct, flattened granules ; eyes slightly convex but small. 

 Thorax a third broader than long, very gently narrowed towards the bisinu- 

 ate base, which has rectangular angles ; apex finely ciliate, almost truncate, 

 with obtuse but only moderately prominent angles ; somewhat unevenly 

 but not deeply impressed before the middle, with coarse granular sculpture 

 there ; sides more broadly concave in front than behind, the granulation 

 not much finer than that of the disc. Elytra of the same width as thorax 

 at the base, twice its length, shoulders obtusely rectangular, a trifle wider 

 before the hind thighs, gradually narrowed posteriorly ; the slender suture 

 is obviously thickened at the summit of the declivity, the distinct costa 

 nearest it extends from base to apex but is curved outwardly in line with 

 sutural elevation, the short second costa begins at the hind thigh but does 

 not reach the extremity, where there is a short plica near its side ; there is 

 only a single series of granides along each side of the suture, the others are
