XXXIX. — Description of a neio Coleopterous Insect from 

 Bounty Island. Bj Capt. Thos. Broun, F.E.S. With 

 Note by J. J. Walker, Esq., F.E.S. 



[The Bounty Islands are a small group of granitic islets and 

 rocks (about twenty in number) occupying- a space of about 

 3 miles by 2, the highest summit being 290 feet above the 

 sea. They are about 490 miles to the eastward of the south 

 extreme of New Zealand, in the lat. 47° -44' S., long. 17b° E. 

 All the islets are entirely destitute of fresh water or land 

 vegetation of any sort, but are frequented by myriads of 

 penguins and other sea-birds. Capt. F. W. Hutton, F.R.S., 

 has described (Trans. N. Z. Inst, xxvii. p. 174, 1894) a 

 large and conspicuous Stenopelraatid cricket, Ischyroplectron 

 isolatum, from the Bounty Islands, and suggests that it may 

 feed on the dead seaweed. — J. J. Walker.]
