124 BLacksurn and Suarp—On some New Species and Genera of Coleoptera. 
Oligota variegata, n. sp.—Linearis; parum nitida testacea; capite prothorace- 
que rufis, abdominis segmentis 1—4 et antennarum apice infuscatis; elytris pro- 
thorace parum longioribus, obscure subtiliter punctatis. Long. 11 m.m. 
Antenne short; joints one and two elongate; three to five about as long as 
broad, and nearly equal infer se; six to nine pretty strongly transverse, and 
increasing in size; ten twice as long as, but scarcely wider than, nine. 
This minute species is allied, I think, to the European O. pusillima, Gr., but is 
even more linear than that insect. Its build, size, colour, and very fine punctua- 
tion of elytra (which under a microscope appear to be minutely wrinkled rather 
than punctate), combine to separate it from all other species of the genus that 
I can ascertain to have been described. 
A single specimen occurred under the bark of a living tree, at an elevation of about 3000 feet, on 
Konahuanui, Oahu.

Oligota prolixa, n. sp.—Elongata, parce punctata, nigra, antennis palpis, pedi- 
busque fusco-testaceis, palpis elongatis ; elytris prothoracis longitudine ; abdomine 
parallelo, elongato. Long. 2 m.m. 
Antenne rather short, almost without club, a little thickened externally ; 
second joint elongate; third, small; fourth, fifth, and sixth, each small; seventh, 
eighth, and ninth, each about as long as broad; tenth, rather large, a good deal 
longer than the ninth. Palpi very elongate, about half as long as the antenne. 
Head narrow and elongate. Prothorax transverse, rather convex, sparingly punc- 
tate. Elytra about as long as, and rather narrower than, the thorax, rather 
coarsely and sparingly punctate. Hind body with the first four segments of 
one width, thence narrowed to the extremity, the two basal segments not closely 
punctate, but less sparingly than those following; the pubescence scanty, but 
rather elongate. 
This insect, I should think, will form a distinct genus; but as I have before me only one individual, 
in a rather dirty state, I cannot investigate it thoroughly. Mr. Blackburn sent it as No. 245, and 
states that the species was beaten from dead branches of trees on Haleakala, in Maui, and Mauna Loa, 
in Hawaii, at elevations of about 4000 feet,

Lithocharis incompta, n. sp.—Depressa, ferruginea, abdomine fusco, antennis 
pedibusque testaceis, elytris in medio transversim obscuratis; crebrius punctata, 
subopaca. Long. 3} m.m. 
Antenne rather short, the terminal joints evidently a little thicker than the 
others; ninth and tenth joints each- rather shorter than broad. Head large, 
slightly broader than the thorax or elytra, densely punctate, vertex a little emargi- 
nate in the middle, the neck rather slender. Thorax rather broader than long, a
