120 BLACKBURN AND SHARP—On some New Species and Genera of Coleoptera. 
Fam. DYTISCIDZ. 
CoPpELATUS. 
Copelatus mauiensis, n. sp.—Elongatus, subparallelus, subtilissime reticulatus, 
niger, capite prothorace antennis palpis, pedibusque rufescentibus; prothorace 
transverso, linea obscure punctata trans partem anteriorem et secus latera tracta 
et ad basin reflexa; elytris punctorum seriebus obscure notatis. Long. 54 m.m. 
Allied to C. parvulus, Boisd., but easily distinguished by its elongate, parallel, 
less convex form, and darker colour; by the more clearly-impressed line (con- 
taining some obscure punctures) surrounding the front and sides of the thorax a 
little within the margin; and the rather strong punctuation which forms a kind of 
reflexed continuation, within the basal angles, of the impressed line. 
A single specimen occurred in a ‘* water-hole ” at an elevation of about 4500 feet above the sea, on 
Haleakala, Maui.

Fam. STAPHYLINIDZ. 
BouirocHaRA. 
Bolitochara impacta, n. sp.—Testacea; antennis incrassatis, nigro-brunncis, 
basi testaceo; prothorace quadrato; elytris brunneis trans basin testaceis; 
abdomine ante apicem infuseato. Long. 24 m.m. 
Probably allied to B. insulana, Fairm, from which it appears to differ in being 
considerably smaller, with the antennz and elytra differently coloured. 
As far as I have been able to examine this minute species, it possesses the 
tarsal characters of Bolitochara. The thorax resembles that of Haploglossa, but 
the head is constricted at the point of insertion in the thorax, though not as much 
as in the European species of Bolitochara. The shape of the thorax gives the 
insect a facies very different from that of Aleochara. The antenne are scarcely 
so long as the head and thorax together, and are very strongly incrassate, 
resembling those of Aleochara mycetophaga, but are even still more thickened. 
The dissection of a specimen of B. impacta might probably lead to the establish- 
ment of a new genus to include its Tahitian ally with it; but as the species is 
unique in my collection, I am unwilling to dissect it, and it must stand for the 
present as a Bolitochara. 
A single specimen occurred in marine rejectamenta on the beach near Honolulu. Repeated search 
in the same and similar localities failed to furnish a second specimen.
