(Sandy Point, Lat. 53°, 10' S., Long. 70°, 54' W., on the 

 Straits of Magellan, capital of the Chilian territory of Magal- 

 lanes) during late November and early December, 1895 by 

 Dr. Ohlin and Dr. O. Nordenskjöld. The specimens from 

 Tierra del Fuego are almost all from the eastern pampas 

 region along the Rio Grande and were collected in February 

 1896 by Ohlin. Only one species, Limnophila eutaeniata 

 BiGOT, is identical with any of the seven species described 

 by BiGOT from the southern Archipelago of Tierra del Fuego. 

 This specimen was secured near the Rio Azopardo in the 

 mountainous region near Admiralty Sound in the south-wes- 

 tern part of the island during the unsuccessful trip to reach 

 Lago Fagnano (Ohlin, 1. c, pp. 178, 179). The Chilian spe- 

 cimens, so labelled, were almost all collected by Dr. Per 

 Dusen in the vipinity of the Rio Aysén. This river reaches 

 the Pacific ocean at about Latitude 45°, 23', 30" S., af ter ha- 

 ving cut its way through the whole of the West Patagionian 

 Cordillera.^ In addition to the Tipulidse herein described as 

 new, Dr. Dusen secured here the type of the handsome 

 Tanyderid crane-fly, Tanydervs gloriosus Alex.
