Coleoptera from Africa and Madagascar. 201 
below the middle; legs elongate; all the tibiz with a small spine ; 
the first joint of the posterior tarsi as long as the two following 
joints together; claws bifid; anterior coxal cavities closed. 
Amongst the genera with closed coxal cavities Otacilus 
would perhaps best be placed amongst the Sermyline, 
on account of the mucronate tibix ; from Merista, which 
has also bifid claws, the genus differs in the longer third 
joint of the antenne, in the more transversely and 
different shape of the thorax, and in the parallel, not 
posteriorly dilated elytra. I would have considered the 
present genus identical with Malaconida, Fairm., had 
not the author described the tibizw as unarmed, and the 
second and third joint of the antenne as equal. 
Otacilus fulvus, n. 8. 
Fulvous; the antenne, the apices of the femora, and the tibie 
and tarsi, black; thorax and elytra closely punctured. Length, 
4—4} lines. 
Head with a few fine punctures between the eyes and deeply 
transversely grooved; the frontal tubercles transverse, strongly 
raised ; the clypeus narrow, triangular; palpi piceous; antenne 
about half the length of the body, black, the third joint one-half 
longer than the second, the following joints elongate (the terminal 
ones broken off). Thorax transverse, the sides rounded before the 
middle, the anterior angles tuberculiform, the anterior and posterior 
margins parallel, the latter rounded, the surface impressed with 
small and smaller punctures, closely arranged, a narrow space at 
the middle more or less smooth; elytra elongate, the sides rather 
strongly deflexed, the surface very closely, finely, and evenly 
punctured ; under side and legs fulvous, the apices of the femora 
and the tibiz and tarsi black. 
Hab. Madagascar. 
The three specimens which are contained in my col- 
lection are probably all females. 
SPILOCEPHALUS, n. g. (Galerucine). 
Body elongate; antenne robust, the second joint short, the third 
slightly shorter than the fourth joint; thorax transverse, with two 
transverse depressions; elytra closely punctured and transversely 
rugose, their epipleurz continued below the middle ; legs unarmed; 
the first joint of the posterior tarsi as long as the three following 
joints together; claws appendiculate; anterior coxal cavities closed. 
Type. Spilocephalus viridipennis.
