Rehn and Hebard (1927) stated that in all probability _flagellata_ does not occur on the island of Puerto Rico. Wolcott (1950) stated that _Symploce ruficollis_ [= _bilabiata_] serves as food for the crested lizard. Cockroaches, Puerto Rico (Schmidt, 1920): Of 100 stomachs examined, 16 contained Orthoptera, including cockroaches.
