nein or little-knoivn Tipulidae. 151 



Faratopoiype, 1 i; paratypes, 2^6, Nelson ; 2 S 6 , 

 1 ? , Takaka, Nelson, Fcbinary G, 19.20 {R. J. Tilbjard). 



The allotype and certain paratypes in the collection of the 

 Cawthron Instilnte. 



G. fiucopin/hiiis is allied to G. neozelundica, Edwards. 

 In his splendid revision of the Tipuloidea of New Zealand, 

 Mr. Edwards has proposed a new subgencric term for this 

 latter species. Since this was written, the remarkable 

 aquatic larvfe and pupa of the Hies 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.
