then rather strongly narrowed, the subapical constriction 
shallow; the upper surface apparently quite smooth, the 
sculpture being entirely hidden by the sealing. Scutellum 
subquadrate, elevated. lytra with the sides shallowly 
sinuate behind the shoulders and somewhat rounded beyond 
the middle, the basal margin jointly trisinuate, the apical 
area not much produced, the apices not pointed and scarcely 
separated, the humeral slope forming a distinct angle with 
the base ; upper surface with a shallow transverse impression 
close to the base, the shallow sulci with large remote punc- 
tures which are not entirely covered by the scaling, the 
alternate intervals strongly raised, the others only slightly 
convex, interval 1 as high as 3 at the top of the declivity ; 
the setz inconspicuous,,;very short and broad, and quite 
recumbent. Legs with dirty white scaling, the front tibi 
brownish ; the front femora without a tooth.

This is the largest species of Hustylus as yet described, 
and is allied to the variable West-Indian /. hybridus, Rosen., 
in which the brown pattern, when present, is very similar. 
The latter species differs, however, in having the two basal 
joints of the funicle equal, while joints 3 to 6 are cylindrical ; 
the rostrum is less dilated in front and the apical slope 
is less abrupt; the rugose sculpturing of the prothorax is 
distinetly appreciable through the scaling, and the alternate 
intervals of the elytra are much less strongly raised. 
Eustylus simulatus, sp. n. 
Colour black, with dense uniform brownish-grey scaling. 
9. Head witha shallow transverse impression behind the 
eyes, which are rather small and not very prominent, the 
width of the forehead evidently greater than the length of 
the eye. ostrum gradually widening from the base to the 
middle, the apical dilatation consequently less abrupt, the 
median dorsal area flat and parallel-sided, the apical slope 
gradual, the scrobe longer than the space between it and the 
eye. Antenne with the scape but slightly compressed, 
gently curved and with erect setee; the funicle with the two 
basal joints subequal, 3, 4, and 7 equal and each a little 
Jonger than 5 or 6, which are themselves equal ; the club 
nearly as long as the three preceding joints. Prothorax 
a trifle longer than broad, the sides subparallel from the 
base to the middle, then narrowed to the apex, the subapicat
