Acad. Sci., August, 190a. 411 that it occurs also on the island of Puna near Guayaquil, Ecuador. Likewise, only one species of Halmenus, H. robustus Scudder, has heretofore been recorded. The material here reported on, however, shows that there are on the Galapagos at least two species including seven races of Sfhingonotus, and three if not four species of Halmenus. Genus Schistocerca. GENERAL REMARKS. Two Galapagos species of Schistocerca have been described, viz. 5." melanocera (Stil) and 5. literosa (Walker).
