NEW OR LITTLE-KNOWN CRANE-FLIES FROM 



FORMOSA (TIPULID^, DIPTERA). /. 



Charles P. Alexander. V 



During the past eight years, numerous important collections 

 of crane-flies have been made in various parts of the island of 

 Formosa so that now we have an excellent foundation for 

 future work on this fauna. A large and valuable collection of 

 Tipulidae and Ptychopteridas has recently been received from 

 Dr. T. Shiraki, Chief of the Division of Entomology of the 

 Agricultural Experiment Station of Formosa. Several species 

 that are undescribed and a number of others that are still 

 insufficiently known were contained in this material so that 

 the collection amply merits a special report. The writer 

 wishes to express his sincere thanks to Dr. Shiraki and his 

 assistant entomologists for the privilege of studying this 

 material. The types are preserved in the writer's collection. 



The following altitudes of stations included in this paper 

 were supplied by Dr. Shiraki: Arisan, about 8,000 feet; 

 Funkiko, about 6,000 feet; Kanshiree, about 1,000 feet; Koshun, 

 about 300 to 500 feet; Musha, about 3,700 feet; Noko, about 

 10,000 feet; Shinchiku (a prefecture; collecting done at 500 to 

 1,000 feet); Shishito, about 1,000 feet;* Taito (a prefecture; 

 collecting done at about 500 feet) ; Tappan, about 3,000 feet. 



The high mountains of Formosa support a rich endemic 

 crane-fly fauna, this including a curious union of Oriental and 

 Holarctic genera. Besides the numerous endemic forms, a 

 considerable number of additional species described from 

 adjoining countries have been taken in Formosa. These 

 include species described from Japan (Alexander), the Philippine
