388 COLEOPTERA. 



not piominent ; the sides moderately explanate, nearly straight but gradu- 

 ally narrowed anteriorly, posterior angles broadly rounded, base slightly 

 bisinuato ; 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 tinnes its length, gradually yet 

 quite evidently curvedly narrowed from the hind thighs backwards ; the 

 central punctation of eacli rather deep, coarse and iri'cgular, 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, 5 mm. ; breadth, 2| mm. , 



Moa Basin, Canterbury. Unique. Discovered by Mr. T. Hall on the 

 20th October, 1913. 



3842. Grynoma clavalis sp. no v. 



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, i'usco-testaceous ; pubescence grey, scanty on the thorax, rather 

 dense and depressed, but a little irregular on the elytra, and intermingled 

 mth 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, shghtly 

 curvedly narrowed anteriorly, almost straight near the base, so that the 

 posterior angles aj)pear 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 efiacement of its lateral punctation, and 

 the abbreviated basal joints of the club. 



Length, 4i 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.
