NKW OR LITTLE- KNOWN NKOTROPK'AL IlEXATOMINI 

 {TIPULIV.E, DIPTERA.) 



By Chas. p. Alex^^nder, 

 Itliaca, N. Y.i 

 The following species were included in collections received for 

 study from the American Museum of Natural History (Mr. Gross- 

 beck); United States National Museum (Mr. Knab); Cornell 

 TTniversity (Dr. Bradley); and the Muzeu Roeha (Senor Rocha). 

 I express my sincere thanks to the above-named gentlemen for 

 this and other favors received from them. The present pajier 

 deals with tlie Hexatomini, an extensive tribe of crane-flies, which 

 reaches its maximum of specific development in the troi)ics. The 

 study of these forms was conducted as research in Sj-slemalic 

 Entomology' at Cornell University under Dr. J. Chester Bradley, 

 to whom I am indebted now, as before, for advice ami many val- 

 uable suggestions.
