TROGOSITIDAE. J5I5 



median depression, its sculpture shallow, similar to that of the head. Scutel- 

 lum pubescent Elytra thrice the length of thorax and of about the same 

 width as it is throughout ; very distinctly, i-ather deeply, but not densely 

 punctate, with subserrate margins. 



Antennae fuscous, shorter than the head and thorax ; basal joint stouter 

 than the next, 3rd longer than either of the following ones, 6th and 7th small 

 and bead-like, 8th very short and transverse ; club densely piibescent. 

 oblong, abruptly enlarged, triarticulate. 



This beautiful little species cannot very well be mistaken for any other, 

 except perhaps the more minute 1593, which bears grey pubescence, and 

 its less transverse thorax is without any central depression. 



Length, 31 mm. ; breadth, IJ mm. 



Tisburv, near Invercargill. One, captured bv Mr. A. Philpott, on the 

 18th January, 1913. 



Group COLYDIIDAE. 



3740. Ulonotus planiceps sp. nov. Ulonotus Erichson, Man. N.Z. 

 Coleopt.. p. 186. 



Oblong, moderately convex, opaque ; obscure fuscous, the basal joints 

 of antennae, front of head and thorax, and the legs more or less slightly 

 rufescent ; irregularly clothed, legs included, with rather short and thick 

 yellowish-grey setae. 



Head subquadrate, quite as broad as the base of thorax, truncate in 

 front, nearly flat, with a few granules on the forehead, antennal elevations 

 slightly prominent ; labrum reddish, distinct, finely punctate and setose. 

 Thorax a little broader than long, the frontal lobes nearly a third of the 

 whole length and projecting as far as the front of the eyes, the 2nd much 

 smaller, not as far from the frontal ones as they are from the base, which is 

 narrow and simple ; disc convex, with a large impression from the apex to 

 the middle, a pair of elongate ones behind, and a median punctiform fovea 

 at the base ; its granular sculpture scarcely discernible. Elytra oblong, 

 considerably curvedly narrowed behind, with oblique shoulders, so that the 

 base is only as wide as that of the thorax, they are double its length, with 

 serrate margins, the apices are not prolonged but there is a slight notch 

 between them ; there is a triangular scutellar depression, behind this the 

 disc is nearly level along the middle, and bears, on each side of the suture. 

 a pair of ill-defined, rather small series of granules, these, however, in some 

 aspects look like punctures, as is often the case in Coxelus ; there are two 

 elongate basal elevations, a pair of distinct nodosities at the top of the 

 hind slope and a smaller in front of these ; outside these, on each elytron, 

 there is a larger one near the hind thigh and a second behind it. 



Legs stout and elongate ; tibiae slightly arched externally, with curled 

 setae there. 



Antennae shorter than the head and thorax, the exposed portion of the 

 basal joint scarcely longer than the stout suboblong 2nd, the next elongate, 

 1th slightly longer than broad, joints 5-8 obconical or submoniliform ; 

 club pubescent, triarticulate, its intermediate joint broadest, the last sub- 

 rotund ate. 



Underside dull fuscous, with thick, decumbent greyish setae. 



After comparison with all the other members of the genus I fail to find 

 any that are at all similar. 



Length, 2§ mm. ; breadth, quite 1 mm. 



Longwood Range, Southland. One example found by Mr. A. Philpott 

 in January, 1913.
