New or L'ittle-lanoumEnotic Tipulidae (Diptera)By Prof. Cnenr,nsP. Ar,nxer.irnn, X'.E.S.
[ReaclOctoberl9th, 1921.]

DumNc the course of the writer's studies on the crdneflies of tropical America, a large number of unclescribedspecieswere d.iscovered,some of which are discussedia
the present paper. The material studied was receivedfrom severalsources,the more important of which are as
follows: British Museumof Natural Historv. throueh thekindness of Mr. Edwards; Hungarian Muieum, t['roughDr. Kert6sz; anclthe Yienaa Museum,through Dr. Zerny.
The latter collectionswere of especialimportance in that,they containedthe type specimensof many speciesdescribedby Wied.emann,Schiner and. Loew. Some of the speciesof the genusErioceradescribedby Wiedemannand Schiner
are re-describedfrom these types. The location of thetypes of the novelties discussedherein is mentioned inconnectionwith each species. The writer would. expresft
his thanks to Mr. Edwards, Dr. Kert6sz and Dr. Zerny
for the privilege of examining these important collectionsof Neotropical Tipulidae.
