﻿A synonymic list of the mosquitoes hith- 

 erto recorded from Sweden, with keys 

 for determining the genera and species.

In connection with a revision of the palaearctic Culicidae, 

 which the writer has in preparation, Prof. Yngve SjöSTEDT 

 was so kind as to send to the British Museum for re-deter- 

 mination the greater part of the collection of mosquitoes in 

 the Stockholm museum. The examination of this material 

 showed, as was expected, that in the case of some of the 

 more difficult groups there were a number of species con- 

 fused. At Prof. SjöSTEDT's request I have prepared a revised 

 list of the known Swedish species, together with tables for 

 their identification, which may be of use to Swedish collec- 

 tors. The species will be more fully dealt with in the forth- 

 coming revision of the palaearctic species referred to above; 

 good descriptions of most of the species (often however under 

 other names) together with their larvœ are given in Mar- 

 tini's recent work, »Über Stechmücken» (Archiv für SchifFs- 

 und Tropenhygiene. Bd. 24, Beiheft i, August 1920), where 

 a fairly full bibliography will also be found. All recent work 

 on mosquitoes has tended to show that the larvae ofier better 

 characters for generic classification than do the adults, and 

 the rather unsatisfactory table of genera given below is about 

 the best that can be made for adults only. For discrimina- 

 tion of species the best characters are to be found in the 

 male hypopygium; but if sufficient latitude is allowed the 

 tables given below based chiefly on colouration will probably 

 be found to work fairly well. Some species are only dis-
