new or little-known Tipulide. 151 
Paratopotype, 13; paratypes, 2 3 8, Nelson; 224, 
19, Takaka, Nelson, February 6, 1920 (R. J. Tillyard). 
The allotype and certain paratypes in the collection of the 
Cawthron Institute. 
G. flavopygialis is allied to G. neozelandica, Kdwards. 
In his splendid revision of the Tipuloidea of New Zealand, 
Mr. Edwards has proposed a new subgeneric term for this 
latter species. Since this was written, the remarkable 
aquatic larvee and pupe of the flies of this genus have been 
discovered by Dr. Campbell and Dr. Tillyard, and there can 
be no doubt but that Edwards’s group deserves full generic 
ranking.
