base to beyond the middle, the subapical constriction shallow, 
the anterior margin slightly rounded dorsally; the whole 
upper surface with very coarse punctures, which are covered 
but not concealed by the scaling. .Scutellum subquadrate, 
very prominent, lytra narrow in the g, much broader in 
the 9, the basal margin jointly sinuate in the middle only, 
the humeral slope running straight to the basal angle, the 
apical area but little produced, the apices scarcely separated ; 
the sulci with large shallow distant punctures, which are 
mostly bare in the centre, with a single scale projecting from 
the front edge; intervals 1, 3, 5, and 7 distinctly more raised, 
interval 1 elevated right up to the base and higher than 
interval 3 at the top of the declivity ; the setz rather long, 
obliquely raised and forming a single row on each interval. 
Legs with dirty white or sandy scaling, usually with a dark 
subapical patch on the posterior femora; the front femora 
with a stout tooth. 
Length 74-10, breadth 23-43} mm.

Kustylus subguttatus, sp. n. 
Colour black, with dense chalky-white scaling ; the head, 
rostrum, and antenne light brown or fawn; the prothorax 
with three very faint and often indistinguishable brownish 
stripes; the elytra with the following small brown dots, 
some or all of which may be absent :—one before and another 
behind the middle on interval 38, and one at the middle on 
interval 5. 
3 2. Structurally very close to H. inclusus, but differing 
as follows:—Antenne with the sete on the scape much 
shorter and more slender. Rostrum with the scrobes less 
curved inwards, the space between them distinctly broader. 
Scutellum scarcely elevated. Hlytra with intervals 3, 5, and 
7 more strongly raised, but interval 1 not raised except on 
the declivity, and there not as high as interval 3; the sete 
much shorter, the rows on the higher intervals duplicated ; 
the punctures almost completely covered, but not hidden, by 
the scaling. 
Leneth 9-11, breadth 33-45 mm.

The Mexican &. sevguttatus, Chmp., which somewhat 
resembles the more strongly marked specimens of this 
species, differs, inter alia, in having entirely recumbent sete, 
the width of the forehead evidently less than the length of 
the eye, and a more slender funicle.
