— 248 -Second Addition to the Knowledge of the Dermaptera and Orthoptera of the Canary Islands by C. WILLEMSE (33rd Contribution to the knowledge of the Fauna of the Canary Islands, edited by Dr. D. L. Uyttenboogaart, and continued by Dr. C. O. van Regteren Altena l)). The list of species of Dermaptera and Orthoptera of the Canary Islands published by me in 1936 (Natuurh. Maandbl., vol. 25) was followed by a first addition in 1949 (Tijds. v. Entomol., vol. 91 (for 1948), pp. 7 — 11). At the time of publication of this addition some works were unknown to me and overlooked. The following additions have therefore to be made.
