The subopacity of the mesonotum, abundance of bristles 

 along the alar margin, the more abundant and pale facial 

 pile, the more abundant pleural pile, the hypogygial tooth, 

 as well as the more robust habitus and its western distribu- 

 tion, are characters of seeming specific importance. 



Undescribed Crane-flies from Argentina 

 (Tipulidae, Diptera) 



BY CHARLES P. ALEXANDER, Urbana, Illinois. 



The species of crane-flies described below were sent to me 

 for naming by Senor Charles Bruch and Sefior Pedro Jorgen- 

 sen-Hansen. Some of the species were taken in the "Puna" 

 or highlands of the Province of Jujuy by Vladimir Weiser, a 

 civil engineer engaged in surveying this country, and kindly 

 included in the material sent me by Sefior Bruch. The types 

 of Tipula moniliferoides were taken at the Estancia of Mr. 

 B. M. Barrett, at Monte Veloz, about 150 kilometers south 

 of Buenos Aires, where most of them were found in the houses 

 in the morning, presumably having been attracted to lights 

 earlier in the evening. The types are preserved in the writer's 

 collection, para types 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 time 

 and elsewhere.
