Africa — Refer to King's Bericht on the Coleoptera of Ma-dagascar ; Insectorum Enumeratio Eleutheratorum, by Gold-fuss. The work of Palisot Beauvois also contains the figures of some species from the kingdom of Ovvare. Asia — Consult Brulle's Voyage in the Morea ; Hope's New Species in Gray's Zoological Miscellany ; Wiedemann's Zoo-logisches Magazin^l8l7 — 1823 ; Perty's Synopsis Coleoptero-rum. Falderman records only a single species^ namely, Cas-sida bella, in his Fauna Entomologica Trans-Caucasica. It seems probable that Cassida may be greatly swayed by the vegetation on which the different species feed. New Holland — Bois Duval's Voyage de L' Astrolabe. REFERENCE TO PLATE IV. 1.
