prothorax with four “ petites élévations obtuses à la partie antérieure et une ligne longi- 
tudinale enfoncée à la partie supérieure.” From these characters it appears to me that 
. the species is very closely allied to, if not identical with, Scar. Melibeus, Fabr.; indeed, 
since the above remarks were written, M. Chevrolat of Paris has sent me a specimen 
labelled ** Lazarus, Fabr. d," which differs only from the typical specimens of Scar. Meli- 
bœus, Fabr., in being rather larger and apparently rather broader. I can, however, detect 
no specific distinctions between them.
