The genitalia of Aedes sylvestris are unique among the species of our fauna. 

 Dr. Felt has founded a genus upon them, but it is not supported by other char- 

 acters. The European A edes vexans Meigen (Culex vexans, Syst. Beschr. europ. 

 zweifl. Ins., vi, 341, 1830; Blanchard, Les Moustiques, p. 309, gives the syn- 

 onjmy =articulatus Rondani = makri«E Grassi), as we have long suspected, 

 proves to be identical with our form and both will have to be included under the 

 earlier name, vexans. Mr. P. W. Edwards of the British Museum has recently 

 compared male genitalia of American and European specimens and finds them 

 the same ; the coloration characters likewise agree. Unfortunately it is too late 

 to maJse' the necessary changes and additions in this work, in conformity with 

 its scope. There is also an African representative in Aedes cumminsii {Culex 

 cumminsii Theobald, Mon. Culic, iii, 314, 1903 ; Culicada mediopunctata Theo- 

 bald, Mon. Culic, V, 304, 1910; Culicada fuscopalpalis Theobald, Mon. Culic, 

 V, 307, 1910; Ochlerotatus cumminsi Edwards, Bull. Ent. Res., ii, 348, .1911), 

 as evidenced by the male genitalia of fuscopalpalis (Theobald, Mon. Culic, v, 

 309, fig. 143). As already indicated in our description, the structure of the 

 claws on the hind feet of the female is subject to variation ; it therefore does 

 not serve for specific diagnosis, as employed by Coquillett (U. S. Dept. Agr., 

 Bur. Ent., Tech. Ser. 11, p. 30, 1906).
