Pitt's Island. 



What, from its narrower abdomen, I take to be the male, has shorter 

 elytra, less drawn out at the apex than the female ; the antennae are 

 about the same length a little shorter than the body in both. This 

 fine species, which at first sight might be taken to be generically distinct 

 from Xylotoles, was found by Mr. Travers on Pitt's Island, one of the 

 Chatham group. 



X. trayersii, Pascoe; Ann. Nat. Hist., July, 1876. X. anguste, 

 ellipticus, nigro-viridis, nitidus, antennis pedibusque ferrugineis, sub- 

 tiliter pubescens ; prothorace laevigato, subtilissime sparse punctate ; 

 scutello transverse, sat dense ochraceo-piloso ; elytris basi prothoracis vix 

 latioribus, subcarinatis, dimidio basali solo parce impresso-punctatis, 

 apicibus rotundatis ; antennis sub-annulatis. 



Long., 3! lin. 



Chatham Islands. 



This species lies between X. costatus and X. nudus in its characters ; 

 the elytra carinated as in the former, but in a much slighter degree, and 

 narrower as in the latter. It was found, with many other interesting 

 species, in the Chatham Islands, b) Mr. H. H. Travers.

 lateribus tumidis. Mesosternum brevissimum. Pro- et mesosterna inter 

 coxas latissima, plana.
