Group COLYDIID^. 



Coxelus xanthonyx, sp. nov. 



Robust, oblong, opaque, fusco-piceous, sides of thorax and the legs 

 rufescent ; with erect, yellow, coarse, but not squamiform setse. 



. Head with indefinite granular sculpture. Eyes prominent and bearing 

 some seta? externally. Thorax almost as long as broad, medially curvate 

 in front ; its sides slightly rounded and explanate, subcrenulate, slightly 

 narrowed behind ; base emarginated towards the sides so that the nearly 

 rectangular angles do not touch the shoulders ; the disc with 1 median 

 impression and 2 indistinct basal ones, its granular sculpture well marked. 

 Elytra oblong, without depressions, each with about 6 series of granules 

 but not distinctly striate ; there is a slight sutural elevation on the top 

 of the posterior declivity. 



Antennae reddish, the club darker, basal joint concealed, 2nd large and 

 thick, 3rd elongate, 4th and 5th longer than broad, 6-8 equal, 9th evidently 

 broader than the preceding ones ; 10th abruptly enlarged, transverse ; 11th 

 subrotundate, narrower than the 10th. 



Tibia' nearly straight, with shorter setse than those on the dorsum, the 

 tarsi with long slender setse underneath the basal 3 joints, claws yellow. 



This has been compared with each of its New Zealand allies, but does 

 not agree with any of them. The central thoracic impression is broad. 

 In most species the elytral sculpture is ill defined, so that series of punctures 

 appear, when viewed in different directions, to be granular elevations.

One, found in decayed Metrosideros in the crater by Mr. W. L. Wallace. 



Coxelus punctatus, sp. nov. 



Oblong, opaque, piceous, legs and antennpe rufescent ; with erect, pale- 

 yellow, moderately coarse setse, the tibia? with shorter and finer setae. 



Head granulate. Thorax rather broader than long, its sides slightly 

 rounded, only a little narrower behind than in front ; with a linear median
