Undescribed Crane-flies from Argentina(Tipulidae, Dipteral
By CnanrBs p. ArBxrrtonn,

Urbana, Illinois.

The speciesof crane-flies described below were sent to me
for naming by Seflor Charles Bruch and Seflor pedro
Jorgen_sen-Hansen. Some of the specieswere taken in the ,ipuia,,
or highlands of the Province of Jujuy by \zladimir W.eiser,acivil engineer engaged in surveying this country, and kindly
included in the material sent me by Seflor Bruch. The typesof Tipula moni,l'iferoideswere taken at the Estancia of -Mr.
B. M. Barrett, at Monte yeloz, about r5o kilometers
southof Buenos Aires, where most of them were found in the housesin the morning, presumably having been attracted to lights
earlier in the evening. The types are preserved in the wriLr's
collection, paratypes of some of the species in the La plata
Museum. I am greatly indebted to the gentlemen above
mentioned for the interesting material described at this timeand elsewhere.
