I. Genus AEDES, Meigen 



Aedes. Meigen, Syst. Beschr. Dip. Vol. I. p. i3 (1818). 



Characters. — Head clothed with narrow-curved scales on the middle, flat ones laterally, 

 rather more spread out than in Culex, the narrow-curved scales forming a broad median area. Thorax 

 with narrow-curved or almost hair-like scales; scutellum with narrow-curved scales; metanotum nude. 

 Wing scales much as in typical Culex, the lateral ones long and thin, the median small and flat; fork- 

 cells moderately long. Palpi small in both sexes; of 2 segments in the (f , of 4 in the 5, apical joint 

 minut.-, mammilliform (traces of 5th segment?) Antennae verticillate in 9 ! densely plumose in the rf . 



Geographical distribution of species. — Four species only known to belong definitely to 

 this genus.

2. Genus AEDEOMYIA, Theobald 



Aedeomyia. Theobald, Mon. Culic. Vol. 2, p. 218 (1901). 



Characters. — Head clothed with narrow fan shaped upright forked scales. Thorax with broad 

 flat spindle-shaped scales; scutellum with broad scales. Abdomen denseby scaled with flat scales often 

 rather irregular. Palpi short in both sexes, scaly. Antennae plumose in (f ; verticillate in the 9 • Legs 

 densely scaled, with dense scab' outstanding tufts. Wings densely scaled, mottled or spotted; wing scales 

 broad and asymmetrical, ver5 - similar to those of Mansonia and also with elongate lateral ones. Forked 

 cells moderately long. 



This genus is easily told by the peculiar wing scales, no other Aedine genus having them at all 

 the same. 



Geographical distribution of species. — Two species only known to occur definitely, but a 

 third described by Skuse as an Aedes probably belongs here.
