BLAcKBURN AND SHarp—On some New Species and Genera of Coleoptera. 191 
under surface is strongly marked and deep. The eyes are rather large, nearly 
circular, coarsely facetted, little prominent, placed on the sides of the head in such 
a position that their hind margins are about intermediate between the back of the 
head and the front of the pseudo-rostrum, their diameter equalling about a quarter 
of the length of the head (including the pseudo-rostrum). The antenne are short, 
and not particularly thick; the scape is slightly bent, of uniform thickness, and 
about as long as the diameter of the eye; in the funiculus the first joint is only a 
little more slender than (and not much less than half as long as) the scape; the 
next is shorter and more slender, but (under a good microscope) well-defined; then 
follow several minute joints (I am not sure whether three or four) very closely 
applied to each other and gradually increasing in stoutness, beyond which is a 
rather large and flattened club considerably longer than wide; the scape, funiculus 
and club do not differ very much in length; the funiculus being, however, some- 
what shorter than the others. The thorax is a little longer than the head (inclusive 
of the pseudo-rostrum), and is quite twice as long as wide, and almost cylindric, the 
front margin being a little narrower than the base, and the sides nearly straight ; 
the margins are not reflexed. The elytra are about half the length of the whole 
insect, nearly the same width as the thorax, quite parallel, and abruptly rounded 
off at the apex. The prosternum and metasternum are very elongate, the meso- 
sternum narrow. The front coxe are nearly circular, rather prominent, and not 
widely separated, the intermediate not much different, and the hind nearly 
contiguous. The thighs are oblong, oval, compressed; the tibiz short, dilated 
from base to apex. Of the tarsi the apical joint is elongate, and the claws are 
larger and stout; the preceding joint is wide, bi-lobed, the first and second joints 
being short and rather broad. The hind body is very similar to that of Pentar- 
thrum.

Dolichotelus apicalis, n. sp.—Linearis ; pallide testaceus, capite infuscato, 
elytrorum basi apiceque (hoc late illo angustissime) et abdomine nigricantibus ; 
capite elongato ; prothorace fortiter elongato, antice vix angustato, lateribus sub- 
parallelis; elytris parallelis obscure nec crebre seriatim punctatis. Long 1} m.m. 
Lat. 1m. ; 
A single specimen was taken from a decaying trunk of a Pandanus, on the mountains near Honolulu. 
The species is probably rare, as frequent search failed to furnish a second example.
