388 COLEOPTERA. 
not prominent ; the sides moderately explanate, nearly straight but gradu- 
ally narrowed anteriorly, posterior angles broadly rounded, base slightly 
bisinuate ; discal punctation fine, rather sharply marked, nearly absent 
along the middle, the lateral sculpture coarser and closer. Elytra very 
little wider than thorax at the base, four times its length, gradually yet 
quite evidently curvedly narrowed from the hind thighs backwards; the 
central punctation of each rather deep, coarse and irregular, that of the base 
finer and closer, the sutural seriate. 
Antennae with robust basal joints, 3-6 slender and elongate, 7th rather 
shorter, club with moderately elongate joints. 
This differs in most details from the type of the genus, Sharp’s G. fusca 
(322), the vestiture, coloration, broader head, more prominent eyes, and 
attenuate elytra particularly. 
Length, 5mm. ; breadth, 25 mm. 
Moa Basin, Canterbury. Unique. Discovered by Mr. T. Hall on the. 
20th October, 1913. 
3842. Grynoma clavalis sp. nov. 
Oblong, subparallel, depressed, subopaque; piceous, about half of the 
thorax outside the middle, and the sides of elytra somewhat rufescent ; the 
marginal channels of these latter, as well as the intermediate and posterior 
tibiae, fusco-testaceous; pubescence grey, scanty on the thorax, rather 
dense and depressed, but a little irregular on the elytra, and intermingled 
with erect, slender, infuscate setae, the lateral setae elongate and white. 
Head rather narrower than the thoracic apex, moderately but not closely 
punctured on the middle. Thorax slightly and widely emarginate in front, 
with obtuse angles ; rather wider behind the middle than elsewhere, slightly 
curvedly narrowed anteriorly, almost straight near the base, so that the 
posterior angles appear rectangular; its sculpture shallow, composed of 
ring-like impressions with a minute puncture in the centre of many of them. 
Elytra about four times the length of thorax, with individually rounded 
apices; they have irregular, coarse, and moderately close punctures; these, 
however, become obsolete towards the apices and sides, which nevertheless 
are not smooth, their sides are explanate. 
Antennae with the basal 2 joints thick and rufescent, 3rd distinctly 
longer than 4th, 5th and 6th subquadrate, 7th transverse ; club large, its 
basal 2 joints transverse. 
This species can be identified by the rather dense, depressed, silvery 
pubescence of the hind-body, the effacement of its lateral punctation, and 
the abbreviated basal joints of the club. 
Length, 44. mm.; breadth, 2 mm. 
Moa Basin. A single example from Mr. T. Hall; 20th October, 1914. 
3843. Grynoma proxima sp. nov. 
Nearly allied to G. clavalis as regards form, coloration, and vestiture. 
The thorax has similar ring-like sculpture but less rectangular posterior 
angles. The elytral punctation is not obliterated near the sides, these are 
less explanate, the apices are simple, and the shoulders obtusely elevated. 
The structure of the antennal club is essentially different, its basal joint 
being evidently longer than broad and narrowed towards the base, the 
next, though slightly shorter and broader, is not transverse.
