Notes on Neotropical dragonflies, or Odonata

Abstract

These notes consist of four brief papers relating to agrionines of the genera Metaleptohasis, Palaemnema, Telagrion, and Protoneura. While these four papers are distinct and of different characters, it is believed that their publication under one general head will be found to be convenient. The Guatemala material was collected by myself; that from British Guiana and Trinidad by my father, L. A. Williamson, B. J. Rainey, and myself.
