GENERAL REMARKS ON THE NEW ZEALAND CRANE-FLY FAUNA. 
The material on which this paper is based consists of (1) a collection 
presented by G. V. Hudson to the British Museum in 1920- 
consisting of duplicates of nearly all the species in his own ыйы 
collection ; (2) a further lot presented by Mr. Hudson to the Cambridge 
Xm. several cotypes, presented to the British Museum by the late 
Captain F. W. Hutton; (4) other material in the old collection of the 
British Museum, including Walker’s types, chiefly collected by Dr. A. 
Sinclair, R.N., about 1850; (5) a small collection made in the neighbour- 
hood of Auckland by Mr. Albert E. Brookes, and presented by him to the 
British Museum in 1919; (6) the Osten- Sacken collection in the Berlin- 
Dahlem Entomological Museum, lent by Dr. orn, containing Osten- 
Sacken’s and Alexander’s types; (7) a considerable collection received on 
loan through Dr. C. P. Alexander, sent to him by Messrs. D. Miller, 
A. Philpott, and x Speight: (8) the types (in the erg Museum) of 
e ed by Mr. C. G. Lamb from Mr. Hudson's Auckland 
Islands iussa i (9) a small collection made by Э М. Wakefield about 
collection in the Berlin Zoological Musei. lent by Dr. G. Enderlein. 
I wish to tender my best thanks to all those who have assisted me in 
the ways indicated, particularly to Mr. G. V. Hudson, to whose generosity 
the British Museum is indebted for by far the greater part of its collection 
of New Zealand crane-flies. The total amount of material examined was 
so considerable, and included such a large proportion of the previously 
known forms, some of which, however, were very imperfectly known, that 
- it seemed desirable to make this paper a preliminary revision of the crane- 
fly fauna of New Zealand. 
Up to the end of 1920 there were sixty-seven A gin of these families 
known from New Zealand (I have sunk three names as synonyms and 
revived three others). Of these species I have ts able to recognize all 
but twelve in the collections examined, and have added no fewer than 
large accessions of new species have still to be made known. Meanwhile 
it may be remarked that the number of known species is even now nearly 
as great as in the British Islands, and very nearly half as great as the 
whole number of New е9 Diptera recorded by Hutton in his 7» 
Faunae Novae Zealandia 1904 
h crane-fly bane à as a whole shows some very interesting features. 
Not the iat striking are some negative points—namely, the absence of
