Scientific Results of the Katmai Expedition 

 OF THE National Geographic Society. 



THE CRANE-FLIES (TIPULID^, DIPTERA). 



Charles P. Alexander. 



The crane-flies collected by Prof. James S. Hine and A. J. 

 Basinger, members of the Katmai Expedition, have been sub- 

 mitted to me for examination. The material is of exceptional 

 interest in the high percentage of undescribed species that it 

 includes. The types of the new species are deposited in the 

 collection of Ohio State University.
