HABITAT: Sierra Leone.
Head small, squarish, and margined in front and the sides; shining black.
Thorax and elytra soot-coloured and velvety, being surrounded along the
sides with an orange border. Scutellum triangular, and rather large.
Abdomen and breast black. Sternum small. Abdominal scales small, but
distinct. Anterior tibiæ with three spurs, the others with two. Tarsal
joints spined within, excepting those belonging to the fore legs, which
are unarmed.
According to Mr. Smeathman, this beetle frequently settles on the thatch of
houses, whence he is of opinion, that it is fond of dried palm leaves,
"where it deposits its eggs." Afzelius however, who subsequently studied
the Entomology and Botany of Sierra Leone with great attention, says,
"Inveni hanc speciem in Sierra Leona mensibus Aprilis et præcipue Majo
copiose in Cassia rugosa, mihi, et in foliis Ficus oblongæ, mihi. Eam in
Jatropha Curcas (non autem Gorcas, ut ait Fabricius) nunquam observare
licuit. Mas abdomine subtus medio sulcato, femina medio convexo." (Schonh.
