The discovery of a species of the tribe Pediciini in 

 New Zealand is of nnnsual interest. I'ricyphona nui'(v- 

 zealniidhe is in all its characters a typical member of the 

 genus. The venation is interpreted as showing a distal 

 fusion of it*] and /?2» the type of venation found in the 

 Pediciini (for a discussion, see * Entomological News/ vol. 29, 

 })p. 201-205, 1918) and very ])ossil)ly in other gronps of 

 Limnolainie, the apparent radinl cross-vein in these cases 

 being the free portion ot vein R.^.

Characters as in Huloru.'<ia, differing as follows : vein M 

 with a strong spur on the caudal side, jutting disto-caudad 

 into cell M. Male hypopygium with the outer pleural 

 appendage narrowed apically into a point, (ionapophyscs 

 appearing as deeply bifid plates, each lobe broadly rounded 

 at ape.x. 



Type of the subgenus : — Holurvsia novarce (Schiner). 



The writer is quite prepared to follow Mr. Edwards in 

 placing the Tipula ?iovarce, Schiner, in the essentially Neo- 

 tropical genus Hulorusia. I'he 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 tern), 

 Zehmdotipula, is proposed for these three New Zealand 

 species. 1'he writer is strongly inclined to believe that the 

 conspicuous spur or stump of a vein in cell M is a character 

 of some phyhjgenetic 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 foi-k, leads one to the conclusion that 

 the character is atavie. 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 and not in 

 alignment with the base of the spur. AVhat this sj)ur on 

 M can represent in the phylogcny of the Diptera is a
