This is the most plentiful region of insect-life, and has a very large 

 and uninterrupted extent of forest-land about the equator. 



Chorisoneura, Phoraspis, Ceratinoptera, Paratropes, Scapteriscus, 

 Rbipipteryx, Orocharis, Moncbeca, Valna, Diplophyllus, Titanacris, 

 Lophacris, Ommatolampis and Tomonotus inhabit Central America. 

 Orocharis, Microcentrum, Rhomalea and Chromacris inhabit Central 

 America and North America. Stenacris inhabits North America. All 

 the rest of the preceding genera exclusively inhabit the 14th region. 

 Hypercompa, Hypnorma, Stenoblatta and Phoraspis have more or less the 

 appearance of beetles. Tabaria and Planoploscelis are allied to the 

 Rhapidophoridse ; the latter genus has an enormous size. Pterochroza and 

 Cycloptera excel all other Saltatoria in the beauty of their wings. 

 Titanacris, Tropidacris and Lophacris exceed all the other species of the 

 locust-tribe in size and in the vivid colours of the bind wings ; and of these 

 three genera, Titanacris, by its largest size and by its purple hind wings, 

 has the pre-eminence. Bufonacris is a strange-looking wingless genus, 

 found near the Straits of Magellan, and corresponds to the South African 

 genus Batrachotettix or Trachypetra. 



Acridium sellatum, found by Darwin at Monte Video, has perhaps 

 too much resemblance to A. peregrinum to be separated from it, but can 

 hardly have been carried by the winds across the Atlantic. A. peregrinum 

 frequently comes to Teneriffe and to Madeira from the coast of Africa, and 

 has been taken 500 miles from land.
