Genus AEDES Meigen 



Aedes terrens Walker. 



Cidex terrens Walker, Ins. Saund., 429, 1856. 

 Stegomyia terrens Theobald, Mon. Culic, i, 305, 1901. 

 Culex terrens Theobald, Mon. Culic, i, 423, 1901. 

 Stegomyia terrens Theobald, Mon. Culic, v, 174, 1910. 



The mount of the male genitalia of the male type shows it 

 to be an Aedes, falling in the oswaldi group. It differs from 

 oswaldi in missing the long subapical seta on the harpago. The 

 single type in the British Museum is much damaged but shows 

 traces of white thoracic ornamentation as in oswaldi. The 

 only mid leg left has a broad white band apically and basally 

 on the first tarsal joint separated by a brown band ; second 

 tarsal joint with narrow basal band ; femur with white streak 

 beneath. Other legs missing or broken. Reported from South 

 America. 



Aedes fluviatilis Lutz. 



Danielsia mediomaculata Theobald is identical, and also Dan- 

 ielsia tripunctata Theobald. Tripunctata is described with 

 white bands on both ends of the joints, but only on some of 

 the joints there are a few pale scales at the apex, the bands are 

 almost purely basal. Fluviatilis and also the male of niedio- 

 macidata sometimes have a few of these apical pale scales. 

 The abdominal markings vary considerably in fluviatilis, the 

 golden scales of the mesonotum of tripunctata could with 

 equal right be called silvery. 



Aedes oswaldi Lutz. 



There are four specimens of Aedes osrvaldi Lutz in the 

 British Museum, from which Theobald made his description
