Abstract

The third instar larvae of Megasoma pachecoi Cartwright, M. punctulatus Hardy, M. thersites LeConte, M. vogti Cartwright, M. cedrosa Hardy, M. elephas (F.), M. actaeon (L.), and M. occidentalis Bolívar y Pieltain, Jiménez-Asúa, and Martínez are described. Preliminary diagnosis for the larvae of Megasoma species from North and Central America and a key to eight species are presented. Comparative, brief descriptions of first and second instar larvae of M. elephas, M. thersites, M. pachecoi, and M. cedrosa, and a detailed description of the male pupa of M. elephas, are also included. Diagnostic structures of immatures are illustrated. Notes on the habits, biology, and distribution of the eight species are reviewed.
