NEW SPECIES OF CRANE FLIES FROM SOUTIIAMERICA. PART IV.+T(Faldly Tiputde, Order Diptera,)
Cs!tuEs P. AGxaNDEr,
A@heret, Massach$etts.

The majority of the speciesdiscrssed at this time werecollected.in Boltu;a by Mr. Schade, and in Colotzblaby Messrs.
George Salt and Fred W. Walker. Fewer specimensare from
Brazil., collected, by Messrs. Davis and Shannon and {romBritish Guiah@,collected by Miss Alice lVlackie, kitrdly sent tome by Professor Cockerell, and by Dr. John G. Myers. A
beautiftd new speciesoI Eriocera Irom Brazil was contained in
the collections of the Deutsches EntomologischesN{useum
and sent to me for [aming by Dr. Walther Horn. I wish to
expressmy sincerethanks to all the above entomologistsfor
this kindly co-operation. Where not stated to the contrary,
the types of the novelties are preserved in my collection.
Only a small part of the collectionsmade by Mr. Walker o11
Mt. Santa Mada are aliscussedat this time, the remaindel
being reserved for consideiation in a later article. This
important collectionis the property of the Museum of Zoologyof the University of Michigan :L!d was loaned to me for study
through the kindnessof ProfessorJ. Spccd Rogers.
