LIMNOPHILA~ Macquart.
The gonus Limnophila, s. 1., includes a conshlerable
number of species found in all regions of thc world. The
structure of the adult flies seems to afford relatively few
characters upon which to subdivide this heterogeneous
aggregation. The genotype, L. pictipennis (Meigen), wasdesignated by W(:stwood in 1840 and so restricts the nameto the small Pal~earetic group that was formerly called
Poecilostola, Schiner, and strictly congeneric groups. Following this strict usage of the name, it seems probable thatfew, or possibly none, of the New Zcaland species so far
described as spccies of Limnophila really belong here. As
indicated by Edwards, L. delicatula, H u t t o n (and serotina,
Alexamter), may be referred to Limnoyhilella, Alexander,
without seriously modifyiag the characters of the latternewor llttle-known Tipulid~e.

group. The remainder of the large and showy species withthe broken areulus described by H u t t o n and Edwards(including all the species in the genus given by Edwards in
his monographic revision, with the exception of bryobia,
Mik, delieatula, Hutton, and skusei, Hutton) would seem tobe referable to Polymoria, Philippi, a group that has, until
now, been represented by a small number of Chilian species.
This genus, Rhamphophila, Edwards, Tinemyia, Hutton, anda few other groups should be referred to the division
Epiphragmaria, as defined by the writer (Cornell Univ.
Agr. Expt. Sta., Mere. 38~ p. 843, 1920). W h e t h e r or not
Polymoria and Epiphragma can be maintained as distinct
is questionable. The basic character of Epiphragma is thepresence of a supernumerary cross-vein in cell C. Several
species, described from the Oriental a~ld Australasianregions, are now known in which there appears a series ofmore or less complete cross-veins in this cell, indicating
the plasticity of the character. I f the eross-veiu in Epiphragraa was lost we would have what to all appearances
would be a species of _Polymoria, or, conversely, if thesenumerous Australasian and Chiliau species of Pol~moria
were provided with this cross-vein, there would be no question of their refereuce to Epiphragma. The structure of theimmature stages, as known, all tends to show the very close
relationships between the various groups of the Epiphragmaria. The author fully realizes the difficulties to be foundiu defining still further generic groups withiu this complex~
yet it is obviously still more unsatisf~tctory to continuallyrefer species of Hexato,nine flies to Limnophila, a genus towhich they are not closely allied. In order to remove threewell-defined groups of the New Zealand fauna from thisartificial situation, new generic terms are proposed herewith
for these groups. Moreover, it seems advisable to treat
Metalimnophila, Alexander, as a genus rather tha~l as a subgeneric concept. Of the New ZealaHd genera, Tinemyia,
Rhamphophila, Polymoria, Nolhophila, Heterolimnphi[a, andAcantholimnophila may be referred to the division Epiphragmaria, based upon the condition of the arculus, while
Zelandoml/ia, l]lelalimnophila, Notholimnophila, and Harrisomyia may be retained in the Limnophilaria. The position,in subtribes, of Elephanlomyia, Ischnolhrix ( Orolimnophila),and Atarba is still questionable, but all three are certainly
members of the tribe Hexatomini. The above distributiou
still leaves a few scattered species in the old genus Limnophila(as skusei, Hutton, nebulifera, Alexander, latistyla, Alexander~
qucesita, Alexander, and oliveri~ Alexat,der), from which they368

This species was based on a single female, and was placed
rather tentatively in Cerozodia with the indication that thediscovery ot~ the male sex might necessitate its removal to
Gynoplistia. During tl,e past season, Harris found the malesex of this insect. Although it rivals in size the known
species of Cerozodia and has nearly apterous females, as is
the case in most species of the latter genus, the structure o{
the antenna proves that it should be placed in Gy,~oplislia,
in which genus it ranks as the largest and most beautiful
species so far discovered. It is most nearly related to thesmaller G. ocellifera, Alexander, which is likewise a winterspecies, and will u.doubtedly be found to have a subapterous
female. The male of G. hiemalis was found by Harris on
June 14, 1923, at Ohakune. On June 22, 1923, a second
male was discovered.
