Length, i lines ; breadth, f line. 



Described from a mutilated example detected in a saw-pit at 

 Parua.

 Niger, opacus, prothoracis elytrorumque marginibus squamosis ; 

 capite prothoraceque crebre punctatis, hoc lateribus rotundatis, 

 margine anteriore leviter bisinuato, angulis posterioribus omnino 

 latissinie rotundatis ; elytris sat crebre punctatis, seriebus quatuor 

 squamorum brevium erectorum. 



$ . Long. corp. (sine mandibulis), 20 mm.; lat., 10 mm. 



Head with numerous punctures on the upper surface, which, on 

 the extreme vertex, become almost dense ; the hind angles slightly 

 prominent, but without any distinct projection. Pro thorax very 

 strongly transverse, with very numerous rather fine punctures ; its 

 front has a slight but distinct margin, which becomes obsolete in the 

 middle, the sides are a little curved, and the hind angles are very 

 broadly rounded ; side margins very densely covered with very short 

 fulvous setae or scales. Elytra short and broad, dull, with four 

 longitudinal series of closely-packed, erect, very short fulvous setae, 

 and with the strongly-raised side-margins very densely covered with 

 similar setae, the surface between the series very distinctly punctured. 

 The upper-inner face of the hind tibia is distinctly longitudinally 

 sulcate ; the apical spurs are broad. 



The male has the mandibles short and stout, strongly curved, 

 with a short basal tooth, which overlaps the labrurn, and a very large 

 tooth in the middle, which, when the mandibles are closed, meets the 

 opposite mandibles just in front of but below the labrurn. The female 

 is unknown. 



Found at Greymouth, west coast of New Zealand, by Mr. Helms, 

 in recognition of whose successful researches I have named the 

 species. There is not, I believe, any species at all similar to it known 

 as occurring in New Zealand.
