Und,escribedSpeciesof Crane-Fliesfrom Chile(Dipt.: Tipulidae).
Amherst, Massachusetts.
By CnaRLEs P. AT,BxANDER,
The speciesherein describedas new were included in extensiveseriesof theseflies taken in the vicinity of Concepcion
and in the Valley of llarga-marga by Fathers Jaffuel andPirion, who have added greatly to our knovvledgeof the faunaand flora of Chile. The types of the novelties are preservedin my collectionthrough the generosityof the collectors. Theirdetailed study of the Valley of Marga-marga (See Jaffuel andPirion, Plantas fanerogamas del Valle de Marga-marga,
Rntista Ch,ilena de Historia Natural, 25:350-4O5; t92L) has
shown that the South Chilean or Antarctic element of thefauna and flora extends much further to the north than has
been generalll/ appreciated,presumably occurring in favoredlocalitiesor "islands." in a manner quite similar to that of theCanadian "islands" in New York and New England.
