XXXIIL. On some new Coleoptera from the Hawatian 
Islands. By D. Suarp. 
[Read October 5th, 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 official 
position, and thus prevented from leaving home. lam, 
however, able to offer to the Society descriptions of 
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 of this 
interesting insular fauna, the entomological portion of 
which, notwithstanding Mr. Blackburn’s successtul efforts, 
is still far from being completely known. 
NITIDULIDA. 
Mr. Blackburn has been very successful in adding to 
the remarkable series of Hawaiian species of this family, 
so that Iam 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 establish- 
ment of two new groups in the genus Brachypeplus, in 
addition to those briefly characterised in the ‘ Trans- 
actions ’ of the Society, 1878, p. 182. 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 1s 
abruptly curved upwards behind the coxe. The species 
approach, on the one hand, to the genus Gonioryctus; on 
the other, to the B. discedens group of Brachypeplus, so
