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 antennas 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 Xy/otoles, was found by Mr. Travers on Pitt's Island, one of the 

 Chatham group.

 scutcllo transverso, sat dense ochraceo-piloso ; elytris basi prothoracis vix 

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

Chatham Islands. 



This species lies between X. costatiis and X. nudiis 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.
