Coleoptera from Africa and Madagascar. 208 
Hallirhotius africanus, n. 8. 
Testaceous or fulvous; the terminal joints of the antenne and 
the tarsi more or less fuscous or black; thorax very finely punc- 
tured; elytra metallic-bluish green, finely punctured, their apices 
fulvous. Length, 3} lines. 
Head broad at the base, the vertex convex, fulvous, very finely 
punctured, with an obsolete longitudinal central groove; eyes 
moderate ; apex of jaws black; palpi long and slender, fulvous, 
the terminal joint long and acutely pointed; antenne about two- 
thirds the length of the body, black, the three basal joints fulvous ; 
the third and following joints long and slender in the male, shorter 
in the female; thorax nearly three times broader than long, all the 
margins nearly straight, the angles obtusely thickened, the surface 
somewhat convex, without depressions, and finely punctured ; 
scutellum fulvous; elytra nearly parallel, the base rather elevated, 
depressed below and within the shoulders, the surface very closely 
and distinctly punctured, metallic dark blue, the apex with a 
triangular-shaped flayous spot; under side and legs fulvous or 
flavous. 
Hab. Zanzibar and Central Africa (my collection). 
SCHEMATIZELLA, n. g. (Galerucine). 
Body oblong; antenne dilated at the terminal joints; thorax 
transverse, the sides subangulate, the angles acute, produced ; 
elytra rugosely punctured, their epipleure extremely narrow ; 
tibie simple, unarmed; the first joint of the posterior tarsi as long 
as the three following joints together; claws bifid; the anterior 
coxal cavities open. 
The widened terminal joints of the antenna, the 
shape of the thorax, scarcely visible elytral epipleure, 
and the bifid claws form a number of characters which 
allow of a comparatively easy recognition of the present 
genus amongst the numerous Galerucide. 
Schematizella viridis, n.s. (Pl. VIL, fig. 11). 
Flavous ; the six or seven terminal joints of the antenne black ; 
the base of the head and the thorax green, rugosely punctured ; 
elytra opaque, green, finely rugose, the lateral margin narrowly 
flavous. Length, 3—38} lines. 
Head strongly rugose at the vertex, the latter metallic-green ; 
lower part of the face flavous; the clypeus forming a narrow
