Insects of the Galapagos (Supplement) By E. Gorton Linsley^ Division of Entomology and Parasitology University of California, Berkeley, California 94720 Abstract: This publication is intended as a supplement to "Insects of the Galapagos Islands" by Linsley and Usinger (1966). Included are all references to Galapagos insects published be-tween 1964 and 1974 which are known to the writer, together with some which have appeared subsequently. A few earlier references which were overlooked originally have also been incor-porated. The format follows the 1966 treatment, except that when families, tribes, or genera have been extensively revised for the Galapagos fauna the new arrangement has been presented in full. Also, authors who have pubhshed significant subsequent information regarding Galapagos insects have been cited in either the generic or species treatments. INTRODUCTION In 1964, the writer and the late Robert L. Usinger were among the entomologists priv-ileged to visit the Galapagos Islands as mem-bers of the Galapagos International Scientific Project. Prior to participation in the Expedition we attempted to assemble as much of the lit-erature pertinent to the Galapagos fauna as possible, and from this literature we compiled a list of the insects known from the archipelago at that time. We were subsequently encouraged to publish this list as a base for reporting dis-coveries made by members of the Expedition as well as specialists who studied their material. This was done (Linsley and Usinger 1966). In the intervening years a substantial number of papers on galapagoan insects have been pub-lished, incorporating not only results from the Galapagos International Project but from other expeditions as well, including, for example, the Mission zoologique beige aux iles Galapagos et en Ecuador (Narcisse et Jeanore Leleup, 1964-1965), the Edinburgh University Galapa-gos Expedition (1968), and collections by vari-ous individuals (Robert Silberglied, 1970; Roger Perry and T. de Vries, 1967-71) and others. The present supplement conforms to the policy utilized in the original list, in that no unpublished records are included and no inde-^ Research Associate, Department of Entomology, California Academy of Sciences. pendent judgement has been passed upon the taxonomic treatment of Galapagos species. However, in cases where families, tribes, or genera have been extensively revised for the island fauna, the new arrangement has been presented, thus replacing the comparable sec-tion in the original list. References to revisions have also been listed under the appropriate tax-onomic category and new records for individual islands have been included and added to pre-viously recorded ranges. The abbreviations of scientific publications generally follow the "BIOSIS list of serials with coden, title abbreviations, new, changed and ceased titles" (BioSciences Information Service of Biological Abstracts), and complete citations to most of the pertinent older references not here given may be found in the 1966 paper. It is too much to hope that the supplement will be fully complete for the period 1964-1974, because of the long delay in the appear-ance of traditional bibliographic reference works. However, if it is reasonably complete and useful to those who are concerned with island faunas and the Galapagos in particular, its purpose will have been served. I have utilized the official Ecuadorian names in the species lists with one exception. Local residents, Ecuadorian scientists and scientific and popular publications using non-English names almost universally refer to "Santa Maria" as "Floreana," and I have followed this usage here as we did in the original 1966 list.
