Epwarps.—Preliminary Revision of the Crane-flies of New Zealand. 299 
Genus Triuicra О.-8. 
Osten-Sacken mentions that he has seen a species of this genus from 
New Zealand. There is a single specimen in the British Museu 
Titirangi, Auckland, 30th December, 1915 (A. E. Brookes), which is too 
. damaged to determine specifically ; it may or may not be the cosmopolitan 
T. pilipes. If it is, it is the only species of crane-fly so far discovered in 
New Zealand which is not endemic to the aberat (See text-fig. B.) 
The terminal joints of the antennae do not seem to be quite as small 
as in T. pilipes, and are scarcely differentiated trom € the others. 
Tribe Limnophilini. 
Leaving out of account for the moment the genera of the Gynoplistia 
group, the members of this tribe are exceedingly difficult to classify, because, 
although the numerous species exhibit an extensive range of structure, 
o 
and the length of the male antennae. It is very probable that the early 
stages will afford a much more satisfactory basis of classification than the 
adults, but until this has been discovered* it seems inadvisable to go much 
further in the subdivision ide the old genus Limnophi 
In endeavouring to over characters which may be useful in defining 
the genera of this сва in a natural manner І have found one which І 
believe may be of аы value: this is the condition of the base 
of the median vein. In Gynoplistia, Cerazodia, Orolimnophila, and Limno- 
phila skusei (text-fig. C) the media is connected with both R and Cu at 
the base ; the connections with R I have spoken of in this paper as the 
“ arcular cross-vein," although it is quite possible that is really not a true 
cross-vein, but the base of the media itself. This, at any rate, appears to 
to regard as the actual base of the media the short vein which arises from 
R still nearer the base of the wing, and fuses with Cu for some distance 
iind separating as the main stem of the media. This condition is found 
also in the great majority of Palaearctic and Nearctic Aer cR er 
I рр, Dicranophragma, Lasiomastiz, Limnophila sensu O.-S., nolabis, 
Eutonia, Poecilostola, Pseudolimnophila, Neolimnophila, Pilaria, нану 
On the other hand, in all the remaining Limnophilini found in New Zealand 
the media arises from Cu a good dea! farther from the base of the wing (the 
above-mentioned fusion with Cu being longer) and has no connection with 
in Epiphragma and also in Linnophile ochracea Mg. „ and in en eris 
It is worth чин that Epiphragma and L. ochracea are wood-feeders, like 
the New Zealand Rhamphophila. 
Another character which may be found to be of generic value when 
fully understood is the presence or absence, before the middle of most of
