BLACKBURN AND SHarp—On some New Species and Genera of Coleoptera. 129 
This obscure little insect is very similar to Acritus insularis, but is readily 
distinguished by the broader tibize and invisible scutellum. 
No. 844; found near Honolulu. 
DIS: 
Bacanius confusus, n. sp.—Breviter ovalis, convexus, ferrugineus, confuse nec 
fortiter punctato-rugatus. Long. 2 m. 
Considerably smaller than B. atomarius, Sh., and having much less distinct 
punctuation. The punctures on the elytra, though not very fine, are obscure and 
confusedly mixed with indistinct wrinkles. On the under surface, the basal seg- 
ment of the hind body is strongly, and the sides of the metasternum (also, so far 
as I can see, the mesosternum) are obscurely, punctured. 
A single specimen occurred on Oahu, but the particulars of the capture have been lost.

ACRITUS. 
Acritus insularis, n. sp.—Breviter ovalis, sat convexus, nitidus, piceus, antennis 
pedibusque fuscis ; crebre, zequaliter, sat fortiter punctatus. Long. 1 m.m. 
Very similar to the European A. minutus, and about the same size but of 
broader form, darker colour, and with more punctate surface. The punctuation of 
the thorax is rather fine, and the transverse series of punctures in front of the base 
is very distinct; the elytra are more coarsely punctate, and the punctuation is 
evenly distributed over their surface, each puncture being round; there is a very 
obscure trace of a curved stria on the basal portion. Beneath, the body is impunc- 
tate in the middle, but rather coarsely punctate at the sides ; the oblique stria on 
the front of the metasternum is obliquely directed outwards and is rather deep, 
but it is not looped upwards behind the coxa, and terminates some considerable 
distance inside of the epimeron. F 
Found near Honolulu. No, 425. 
ZELETES, 
ZEletes longipes, n. sp.—Oblongo-ovalis, minus convexus, piceo-ferrugineus, 
nitidus, levigatus; metasterno anterius vage lateque impresso, Long. 14 m.m. 
(Plate 1v., f. 13.) 
This insect is less convex than J. facilis, and is readily distinguished by its 
impunctate surface ; it is probably allied to Acritus politus, Lec., but that species 
is described by Horn as possessing a longitudinal groove on the mesosternum, and 
is smaller; in AX. longipes there is only to be seen a vague nearly round depression 
at the junction of the meso- and metasterna. 
No. 252. Found at an elevation of 4000 feet, in Hawaii,
