On new Coleoptera from the. Auatrnlian Ilegiou. 283 



There are two species with wliich E. prodactn niij^ht be 

 confounded; from E. furentu awX E. latirostris the distinctly 

 separated segments which preclude the hist will at once distin- 

 guish it, as well as the character of the basal joint of the 

 antennules and the exact structure of the rostrum. 



R<"»dberg, on the precipices among Alcyonarians, in about 

 150 fathoms. 



Sars described the species from a single specimen, which 

 was scarcely more than half the length of those found by me ; 

 and as in that description there is no allusion made to the 

 structure of the antennules, I should have failed to recognize 

 the species had it not been that I had the advantage of 

 direct comparison with specimens kinUy given me by 

 Prof. G. O. Sars, and obtained by him in West Norway.
