I am unable to find any close ally to this species 

 among the European forms; the pilosity of the male anten- 

 nae is very like that of L. prolixicornis Lundstr. 



Had the male and female specimens been from 

 different localities it would hardly have occurred to me that 

 they are conspecific, but as they were found together in 

 the same locality the same day there can be no doubt that 

 they appertain to the same species. 



In his List of Dipterous Insects in the British Museum, 

 Vol.1, Walker has described five new species of Tipulidae 

 from the province Finmarken in Northern Norway. They 

 were all referred to the genus Limnobia, but to different 

 divisions characterized by the wing-venation. This work- 

 was unknown to Zetterstedt, and Walker's species 

 are not mentioned by him. Mr. F. W. Edwards of the 

 British Museum has at my request kindly examined the 

 types of these species and informed me that their syno- 

 nymy is as follows. L. excisa Walk, is identical with Dicra- 

 nomyia mitis Meig. Of the two specimens of L. reperta 

 Walk, the one from Alten is Dicranomyia stigmatica Meig., 

 the other, from Hammerfest, is D. morio Fabr. L. separata 

 Walk, is Limnophila nemoralis Meig. The two following 

 species have been described later under other names.
