Note 738 — LETTER XXXII.
Reading edition
As Dynastes Actæon, Elephas, Typhon, &c. differ from D. Hercules, &c., not only in their general habits, horns, &c., but also in their maxillæ and labium,—the former in D. Actæon being simple, and in D. Hercules toothed, and the labium of the first bilobed at the apex, and in the last entire and acute,—according to the modern system they ought, therefore, to be considered as distinct genera. I would restrict the name Dynastes to D. Hercules and its affinities: D. Actæon, &c. I would call Megasoma.
