Coleoptera from Africa and Madagascar. 199 
AntHonea, Baly. 
The anterior coxal cavities in this genus are closed ; 
this and the mucronate posterior tibiz would place 
Aethonea in the twentieth group of Chapuis’ arrange- 
ment, the Sermyline. The serrate antenne seem to be 
peculiar to the male sex only, at least in the species 
here described. Ootheca serricornis, Thoms., belongs 
doubtless to this genus. 
Aethonea variabilis, n.s. (Pl. VII., figs. 14, 15). 
Fulvous; the antenne (the three basal joints excepted), the 
femora, and tibie partly, black; thorax finely, elytra closely, 
punctured, the latter with four small black spots placed trans- 
versely. 
Var. a. The sides of the thorax and the lateral margin of the 
elytra below the middle black. 
Var. 6. Elytra black, the shoulders and the suture fulvous. 
Var.c. Elytra entirely black. 
Var. d.  Elytra without any black markings (A. Murray? ?, 
Baly). Length, 4—43 lines. 
Head with a few fine punctures, longitudinally grooved at the 
middle; antenne half the length of the body, the second and third 
joints very small, equal, the fourth longer than the three preceding 
joints together, the third and the five following joints serrate in 
the male, simple in the female; thorax at least three times 
broader than long, the sides rounded, the posterior margin some- 
what obliquely shaped at the angles, nearly straight at the middle, 
the surface with some fine rather scattered punctures; elytra 
convex, scarcely widened posteriorly, longitudinally depressed 
within the shoulders, more strongly punctured than the thorax, 
the punctuation close and here and there arranged in rows, the 
interstices slightly rugose, and forming occasionally narrow smooth 
longitudinal ridges; under side and legs variable in colour. 
Hab. Old Calabar, Maemba, West Africa (my col- 
lection). 
In a single female specimen, which agrees in most 
respects with the males, the antenne are simple, the 
third joint is slightly longer than the second, and the 
fourth as long as the three preceding joints; the apical 
joints are distinctly shorter. In this specimen the 
thorax has a black band at each side, and a similar 
band is placed from the middle of the lateral margin to
