BLACKBURN AND SHARP—Onx some New Species and Genera of Coleoptera. 147 
The black patch of the elytra sometimes extends to the sides, and covers all 
the basal portion. The species is allied to a Californian one returned to me from 
Dr. Leconte a few years ago without name, but is apparently distinct.

Scymnus ocellatus, n. sp.—Parvus, rotundulus, obsolete punctatus, conspicue 
pubescens, testaceus, prothorace in medio elytrisque signaturis nigro-fuscis, cor- 
pore subtus exparte majore nigricante. Long. 13 m.m. 
This small insect has peculiar markings: there is a large triangular black mark 
round the scutellum, which is prolonged backwards along the suture, and just 
behind the middle is turned outwards on each side, so as to form a curved transverse 
prolongation, and just in front of the termination of this is a circular spot; the 
outer margin is also dark, the dark colour being, however, nearly divided on a 
line with the termination of the curved mark. The punctuation of the surface is 
very obsolete, though the pubescence is conspicuous. A second specimen has the 
under surface pale, and the dark thoracic mark nearly absent, perhaps indicating 
immaturity. 
D.S. 
Scymnus discedens, n. sp.—Minutus, valde convexus, testaceus, nitidus, obso- 
lete punctatus, parum perspicue pubescens ; metasterno anterius inter coxas inter- 
medias linea abrupte curvata, longius producta. Long. 1} m.m, 
Thorax impunctate, with an extremely delicate pubescence easily removed, 
then appearing shining. Elytra more distinctly punctured than the thorax, but 
still only finely and obsolete; upper surface entirely yellow ; the thorax scarcely 
darker ; under surface more ferruginous. 
This little insect, of which I have seen but a single specimen, will probably 
prove to be the type of a new genus, owing to the fact that the metasternum is 
distinguished from the mesosternum by a remarkably distinct raised line, which is 
greatly produced in front, so that the mesosternum is much reduced. 
The species is rare; Mr. Blackburn has twice found it by sweeping, in Oahu. No. 337.

ATTAGENUS. 
Attagenus plebeius, n. sp.—Sat elongatus, opacus, dense pubescens, niger, 
antennis pedibusque rufis, capite, thorace, elytrorumque fascia angusta, angulata, 
subbasali pubescentiz pallide. Long. 4—44 m.m., 
Similar in size, form, and appearance to the European A. verbasci, but with 
only one pale band on the elytra. The specimens described are probably of the
