( 507 ) XXXIII. 0)1 some new Coleoptera /ro?/i the Hawaiian Islands, By D. Sharp. [Read October 5tli, 1881.] Since my last paper on the Sandwich Islands Coleoptera was published by the Society, Mr. Blackburn has been able to give but little attention to Entomology, owing to his being much occupied with the duties of his ofticial position, and thus prevented from leaving home. I am, however, able to offer to the Society descriptions ot thirty-four new species, a large portion of which are due to a visit Mr. Blackburn was able to make to the large island of Hawaii a year or two ago. I hope before long to make another contribution to a knowledge ot this interesting insular fauna, the entomological portion ot which, notwithstanding Mr. Blackburn's successful efforts, is still far from being completely known. NITIDULIDiB. Mr Blackburn has been very successful in adding to the remarkable series of Hawaiian species of this family, so that I am able to describe here eleven new species and yet have been obliged to leave untouched several obscure forms, which, in the absence of sufficient material, could not with certainty be treated as distinct species These new discoveries necessitate the estabUsli-mentof two new groups in the genus Brachypeplus, m addition to those briefly characterised m the Trans-actions ' of the Society, 1878, p. 132. _ The first of these groups consists of species of small size, and but little depressed form, the elytra especially being convex or subinflated, the eyes are moderately large, and do not extend quite to the hind margin of the head, although they may nearly attain it ; but the group is especially characterised by the fact that the prosternal process is abruptly curved upwards behind the coxae, ihe species approach, on the one hand, to the genus Gonioryctm; on the other, to the B. discedens group of Brachypeplus, so TRANS.
