UNDESCRIBED CRANE FLIES FROM FORMOSA AND 



LUZON (TIPULID^E, DIPTERA) 



By Charles P. Alexander 



Of Amherst, Massachusetts 



All but one of the new species of crane flies described in the 

 present paper were collected in Formosa (Taiwan) by Dr. Teiso 

 Esaki during his recent collecting trip (August to October, 1921) 

 to that island. The majority of these species were collected 

 in the high mountains, which support a rich endemic tipulid 

 fauna. The interesting new Pselliophora was collected by Dean 

 C. F. Baker in northern Luzon. My thanks are extended to 

 Doctor Esaki and Dean Baker for the privilege of studying these 

 highly important collections. The Formosan types are pre- 

 served in my collection through the generosity of Doctor Esaki.
