The extension of the range of this species to the tropics is inter- 

 esting. It has hitherto been recorded only from the eastern United 

 States. It was bred from large, dark, fat-tubed larvae, which were 

 found in enormous numbers, together with Jaiithinosoma posticata, 

 in a newly flooded meadow near Las Cascadas. 



The adult was also taken repeatedly at La Boca, Pedro Miguel, 

 and at Colon.

Bred from larvae occurring in countless numbers in the brackish 

 swamp at La Boca. Adults were collected by Mr. Jennings in the 

 barracks at Pedro Miguel. The species is a well-known inhabitant 

 of brackish marshes on both the Atlantic and Pacific coasts of the 

 United States. 



AEDES POSTICATA Wiedemann 



The large, fat-tubed larvae of this species were taken and bred in 

 numbers from a recently flooded meadow near Las Cascadas ; also 

 from still pools of a nearly dried-up mountain stream emptying into 

 the upper Chagres River and from a shallow pool formed by a 

 slow-running stream on Taboga Island. The adults were repeatedly 

 captured, when they came to bite, in the bush around Tabernilia and 

 Lion Hill. 



AEDES LUTZII Theobald 



Several adults were taken in the bamboo and palm swamps around 

 Tabernilia and Lion Hill, where they came to bite. The larvae were 

 not found, nor have thev been bred in the United States.
