New Ant‐Lions From the Southwestern United States (Neuroptera: Myrmeleontidae)

Biological Laboratories, Harvard University In the course of identifying material from the Southwest, the writer has encountered several new species and a new genus of Myrmeleontidae. Descriptions of these are given below, with a list and key to the species of the genus Eremoleon Banks. Sources of specimens are designated by the following abbreviations" CAS, California Academy of Sciences; CI,S, California Insect Survey, University of California, Berkeley; UCD, University of California, Davis; UCR, University of California, Riverside; UCLA, University of California at Los Angeles; LAM, Los Angeles County Museum; MCZ, Museum of Comparative Zoology, Harvard. The kindness of the staffs of these institutions in lending material is gratefully acknowledged. The terminology .of the wing venation as used herein differs from the usual system (summarized by Markl) in several fundamental aspects. Markl’s study is an excellent and invaluable treatment of the comparative morphology of the wing of the ant-lions, but unfortunately his scope, a tribal revision, was so large as to have discouraged detailed investigation of venation in other families. The best clues to the homologies of the myrmeleontoid wing are to be fcuncl in the primitive myrmeleonoidsthe Osmylidae and the Myiodactylidae. A thorough account of the reasons for the adoption of the present system will be given in a forthcoming paper, dealing with the venation .of the order as a whole. In both wings, MA has become coalesced with Rs; the "basal piece" (Figure 8, "b") is to be seen at the base of the fore wing between R and MP. In the hind wing the basal Published with t.he aid of a grant from the Museum of Comparative Zoology, Harvard College. Markl, W., 1954, Verh. d. Nturforschenden Ges. Basel 65:178-263.
