middle, thence rounded ; surface slightly dilated at posterior third, 
then strongly convex to apex, closely squamose, the scales cinnamon- 
brown on the 2nd, 4thand Gth interstices, yellow on the rest of the 
elytra ; striate, the stric rather wide, with distinct punctures, inter- 
stices flat, eranalate at base, 2nd widened at base and on summit 
of declivity, 1st, 3rd and outer interstices inconspicuously 
tuberculate towards apex. Underside ferruginous, scantily pube- 
scent, strongly punctuate on metathorax and two first abdominal 
segments, Legs ferruginous, anterior tibize with strong out- 
wardly directed spines at outer apical angle. 
Phleosinus dubius, sp. n. 
Ovalis, niger, subopacus, antennis tarsisque ferrugineis ; capite 
punctato-granulato, brevissime piloso, haud rostrato, fronte supra 
os deplanata, in medio carinata; prothorace transverso, antice 
gradatim contracto, supra convexo, linea media passim ele- 
vata, rugose punctato, parce squamoso; elytris subcylindricis, 
lateribus post medium subrectis, striatis, striis obsolete punctatis, 
interstitiis squamosis, squamis fuscis, in interstitiis lo, 30, 50 non- 
nihil dilutioribus, his versus apicem tuberculatis. Long. 2°2 mm. 
One specimen, Kurigahara. 
Very similar to P. pulchellus, with the appearance of being a 
colour variety, but differing in certain other points. Entirely 
black with only the antennee and tarsi reddish ; head less strongly 
impressed over mouth, and frontal carina less acute. Prothorax 
narrower, flatter throughout with the sides more gradually sloped 
towards the apex, and not strongly rounded in the middle, so 
that the apical constriction is less marked; punctuation less 
strong and interstices covered with fine reticulation, not evident 
in P. pulchellus. Wlytra more oblique at base, with borders 
straighter, not evidently dilated behind the middle, the sides 
consequently not subsinuate, but straight to near the apex ; 
humeral elevations small, distinct, black, covered behind the 
middle (the base is probably rubbed in the single specimen), 
with fuscous scales, which are obscurely lighter on the alternate 
interstices, as in 2. pulchellus. Stris finer, not evidently punctured, 
the 2nd interstice narrower and straighter throughout. Apical spines 
of the anterior tibiz longer, curved backwards, and connate for 
the greater part of their length, 
The two preceding species resemble small species of 
Hylesinus rather than see osinus, owing to the thickness 
of their scaly covering; but they present no characters 
to separate them from the latter genus.
