constriction rather well marked ; the coarse punctation clearly 
visible through the scaling, and a distinct trace of a shallow 
central furrow. Scutellum longer than broad, narrowing 
towards the base. /ytra narrowly elongate, not sinuate 
behind the shoulders and scarcely dilated beyond the middle, 
the basal margin straight except for a median sinuation ex- 
tending to stria 2 on each side, the humeral slope running 
straight to the basal angle, the apical area scarcely produced, 
the posterior declivity consequently steeper than usual, the 
apices separately rounded ; the shallow sulci with numerous 
closely set punctures, which are covered but not hidden by 
the scaling, the alternate intervals distinctly raised, the others 
almost flat, interval 1 elevated almost as far as the base; the 
setee moderately long, stout, and erect, each interval bearing a 
single row, but on the raised ones the setze are doubled here 
and there. Legs with uniform brownish-grey scaling, the 
front femora obtusely angulated but without any tooth. 
Length 94, breadth 4 mm.

I have retained Chevrolat’s MS. name for this species. 
Eustylus sordidus, sp. n. 
Colour black, with uniform dirty white scaling. 
@. Very similar to £. s¢mulatus, but differing as follows :— 
Head with the transverse impression slightly more pre- 
nounced, the eyes rather larger, the width of the forehead 
but little greater than the length of the eye. Rostrum 
parallel-sided in the basal half, the apical dilatation rather 
more abrupt. Antenne with the scape proportionately 
shorter; joint 6 of the funicle not shorter than 7 ; the club 
only a little longer than the two preceding joints. Pro- 
thorax parallel-sided to beyond the middle, the subapical 
constriction somewhat more strongly marked, the disk less 
convex and with no trace of central furrow. Hlytra much 
shorter in proportion to the breadth, the humeral slope 
forming an angle with the base. 
Length 8, breadth 3? mm.

Eustylus simplex, sp. n. 
Colour reddish brown, with uniform dense grey scaling. 
?. Head with a marked transverse impression, the width 
of the forehead rather less than the length of the eye; the 
eyes very large and not very prominent, the facets absolutely 
flat. Lostrum parallel-sided in the basal half, the genx
