120 3Ir. II. TV. Bates on the Longtcorn 



Xylotoles nudus, n. sp. 



X elongatus, augustus, cuprascenti-niger, glaber, nitidus ; elytris 

 basi thorace vix latioribus, apice utrinque productis et paulo 

 divaricatis, basi grossissime lineatirn punctatis ; antennis pedibus- 

 que castaneia ; femoribus obscurioribus. Long. 4|-5 lin. 



Body entirely destitute of pubescence, except spots on the 

 sides of the ventral segments ; antennae and legs finely gri- 

 seous pubescent. Colour glossy coppery black ; head and 

 thorax impunctate and smooth. Elytra elongated, not per- 

 ceptibly broader at the base than the thorax, very slightly 

 bulging in the middle, and gradually narrowed and prolonged 

 at the apex, where they are slightly divaricate ; the surface 

 has rows of very large punctures, from the suture to the sides 

 and extending to the middle. 



Several examples sent from Auckland by Mr. Lawson. 



Xylotoles rugicottiS) n. sp. 



X. fusco-niger, subasneus, nitidus ; thorace elongato-quadrato, supra 

 passim transverse rugato ; elytris ellipticis, apice utrinque pro- 

 ductis, acutis, supra striatis interstitiis elevatis, fulvo-guttatis ; 

 antennis pedibusque castaneis. Long. 4-6 lin. <$ $ . 



Distinguished by the thorax being elongate-quadrate in out- 

 line, a little dilated immediately behind its anterior angles, where 

 it is widest, and covered with irregular transverse wrinkles. 

 The sides have some patches or lines of tawny pubescence, as 

 well as the front of the head. The elytra have no distinct 

 shoulders, and are dilated in the middle, whence they taper 

 gradually to the pointed apices, most prolonged in the male, 

 but not divaricate ; their surface is coarsely sculptured, 

 deeply striated almost to the apex, and marked with large 

 punctures. The underside is very glossy, with spots of tawny 

 tomentum on the sides of the breast and abdomen. 



Auckland (Mr. Lawson) ; a few examples. 



Xylotoles Icetus, White, Voy. Ereb. & Terr., Ins. p. 22. 



This species (if I refer it correctly to White's X. Icetus) is 

 shorter and much more ovate than its allies, the apices of the 

 elytra not being produced, but somewhat obtusely rounded 

 together. The colours are more gaily metallic. White 

 describes the thorax as violet, and the elytra green ; but in a 

 larger series many varieties are seen, some being wholly 

 brassy green, others coppery or violaceous ; the thorax and 

 elytra concolorous or not. The elytra are narrow and rounded
