UNDESCRIBED SPECIES OF CRANE-FLIES FROM 

 NEW ZEALAND. 



(Tipulidae, Diptera). 



By Charles P. Alexander. 



The new species of New Zealand Tipulidae described in this 

 paper were included in extensive collections sent to the writer 

 by Dr. Campbell, collected by Messrs. Gourlay, Harris, Howes and 

 himself; collections from Dr. Tillyard and Mr. Philpott in the 

 Cawthron Institute; and a small but interesting lot from the 

 alpine zone of Mt. Ruapehu, sent by Mr. Watt. The writer is 

 very greatly indebted to all the above mentioned gentlemen for 

 this material. The holotypes are preserved in the writer's 

 collection except where stated to the contrary. 



Mr. F. W. Edwards, of the British Museum of Natural 

 History, has recently completed a monographic review of the 

 New Zealand Tipuloidea. The writer would express his most 

 sincere gratitude to Mr. Edwards for the privilege of studying 

 this manuscript in advance of publication. The appearance in 

 press of this great work will do much to stimulate the study of 

 the very interesting crane-fly fauna of New Zealand. In addi- 

 tion, the writer has availed himself of the opportunity to sub- 

 mit certain doubtful species of the very large genus Gynoplistia 

 to Mr. Edwards for his expert opinion and comparison with the 

 unrivalled series of types of New Zealand Tipuloidea in the 

 collection of the British Museum.
