Holotype, &, Dunedin, Otago, November 5, 1921 
(G. Howes). 
The discovery of a species of the tribe Pediciini in 
New Zealand is of unusual interest. Tricyphona nove- 
zealandie is in all its characters a typical member of the 
genus. The venation is interpreted as showing a distal 
fusion of A, and R,, the type of venation found in the 
Pediciini (for a discussion, see ‘ Entomological News,’ vol. 29, 
pp. 201-205, 1918) and very possibly in other groups of 
Limnobiinze, the apparent radial cross-vein in these cases 
being the free portion of vein Ry. 
Genus Hotorusia, Loew. 
ZELANDOTIPULA, subgen. nov. 
Characters as in Holorusia, differing as follows: vein M 
with a strong spur on the audal side, Jutting disto-caudad 
into cell M. Male hypopygium with the outer pleural 
appendage narrowed apically into a point. Gonapophiyses 
appearing as deeply bifid plates, each lobe broadly rounded 
at apex. 
Type of the subgenus :— Holorusia novare (Schiner). 
The writer is quite prepared to follow Mr. Edwards in 
placing the Tipula novare, Schiner, in the essentially Neo- 
tropical genus Holorusia. The three species of the group 
from New Zealand known to the writer exhibit certain 
characters that seem to warrant their removal from typical 
Holorusia in some degree, and so the new subgeneric term, 
Zelundotipula, is proposed for these three New Zealand 
species. The writer is strongly inclined to believe that the 
conspicuous spur or stump of a vein in cell J/ is a character 
of some phylogenetic significance. Although it is lacking 
in some individuals, it is usually present as a strong spur, 
or, In some cases, as a more or less complete cross-vein in 
cell M. The course of the spur, and especially the slight 
cephalic deflection of the main vein immediately beyond it 
to form a symmetrical fork, leads one to the conclusion that 
the character is atavic. In the specimens seen by the writer 
where the cross-vein is most nearly complete, the caudal 
portion of the vein, nearest vein Cu, is weak aud not in 
alignment with the base of the spur. What this spur on 
M can represent in the phylogeny of the Diptera is a
