Culex coronator apparently extends its range throughout Brazil, having been 

 recorded by Theobald and others under the name Culex cingiilatus Fabricius, 

 mixed with other similar species. Peryassii figures a larva apparently of this 

 species as that of Culex cingulatus (Os Culicideos do Brazil, fig. 43), and his 

 description (loc. cit., p. 200, 1908) agrees with adults of Culex coronator; but 

 adults sent us by Dr. Lutz from Sao Paulo, Brazil, as Culex cingulatus represent 

 a different although similar species. As to the correct identification of Culex 

 cingulatus Fabricius, the type is in the Zoological Museum at Copenhagen. 

 Wiedemann gives a careful redescription of it, stating it to be yellowish, with 

 white rings at the bases of the tarsal joints, and about 6 mm. long. Dr. Boving 

 has kindly examined the type at our request and informs us that the tarsal an- 

 nulations are basal only. From this it is obvious that Culex cingulatus can have 

 nothing to do with the species under consideration ; recently Dr. Arthur Xeiva 

 has examined the type and identified it as a species which we are treating under 

 the genus Psorophora. Theobald has recently expressed a belief that Culex 

 tibialis Robineau-Desvoidy is referable here, but without giving a reason (Mon. 

 Culic, V, 350, 1910). It is clear from the description that Culex tibialis is a 

 Psorophora, in the restricted sense, and it already has been made a synonym of 

 Psorophora ciliata.
