Proceedings of the United States National Museum SMITHSONIAN INSTITUTION . WASHINGTON, B.C. Volume 117 1965 Number 3508 MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS By J. F. Gates Clarke Chairman, Department of Entomology Introduction It has been my privilege and pleasure to study the Microlepidoptera collected in the Juan Fernandez Islands in 1951, 1952, and 1955 by Dr. Guillermo Kuschel, Centro de Investigationes Zoologicas, Uni-versity of Chile, Santiago, and to him my thanks are due for this opportunity. Through the coui-tesy of Dr. Kuschel I have been permitted to deposit the types of all the new species in the collection of the U.S. National Museum, Smithsonian Institution. Paratypes of some of the species, where series permitted, are also in the Museum, while others are distributed in the Natural History Museum and the University of Chile in Santiago. My sincere thanks are due Dr. Lars Brundin, Naturhistoriska Riksmuseum, Stockholm, for his generous permission to study Auri-villius' types deposited in that institution. To Mr. John D. Bradley, Department of Entomology, British Museum (Natural History), I am also grateful for his help received on many occasions. The drawings for this paper were made by Mr. Arthur D. Cushman, staff artist of the Entomology Research Division, U.S. Department of Agriculture; Mrs. Patricia Hogue; Mrs. Caroline Lutz, staff artist, Department of Zoology, Smithsonian Institution; and by myself. 1
