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, " Ihveni banc speciem in Sierra Leona mensibus Aprilis et 

 prajcipue Majo copiose in Cassia rugosa, mibi, et in foliis Ficus oblongsB, mihi. Earn in 

 Jatropha Curcas (non autem Gorcas, ut ait Fabricius) nunquam observare licuit. Mas 

 abdomine subtus medio sulcato, femina medio convexo." (Schonh. Syn. Ins. iii. p. 128.)
