 multiple head hairs, while they are simple in (juaylei^ and there are 

 some other differences in detail. 



AEDES DAMNOSUS Say. 



Larva^ w^ere taken on the salt marsh at San Diego at the time sqiimniger 

 was flying. Again, when squamiger was in larva, the daiiinoms were 

 on the wing, their hatching and development following more imme- 

 diatelv the inundation of the upper reaches of the marsh by the 

 monthly tides than in the case of Hquarn'ujcr. 1 found the larvie again 

 at Carpinteria, near Santa Barbara, having just hatched in a high 

 tide that iilled the marsh. The species Avas not seen farther north, 

 being replaced by quaylel. The habits of the larvtis differ somewhat 

 from the damnosu-s of the Atlantic coast. There the^^ inhabit pools 

 removed from the immediate action of the tides, often largely or 

 wholl}" fresh, though near the sea. In California they frequented the 

 immediate tide water and developed faster than the other associated 

 species. The difference ma}^ be due to climatic causes, as there are 

 no partly or wholl}^ fresh pools in California, all the water on the 

 marsh coming from the sea, except the river channels, which are unfit 

 for breeding-. 



AEDES QUAYLEI Dyar and Knab {lativittatMs Coquiirett). 



The salt marsh species of the Pacific coast was not encountered 

 south of San Francisco Bay. It was common in all suitable places 

 farther north. These places are rather widely separated, as most of 

 the coast is steep or rocky and forms no tide-water marshes. Larvae 

 were found in tide-water pools at Eureka, California, and Tacoma, 

 Washington. The adults were taken also at West Seattle, Washing-- 

 ton; Stanley Park, Vancouver, and Duncans, British Columbia. The 

 dorsal thoracic ])and of dark brown is usually broad, but varies, in 

 one specimen from the salt marsh being very narrow. This species is 

 far less troublesome than its Atlantic representative, ^ledcs .soil ici fans 

 Walker, although perhaps the most annoying of the California mos- 

 quitoes in the da3'time. In Stanley Park, Vancouver, British Colum- 

 bia, the species was really a naisance in a limited area, though the 

 adults had probably not flown over a mile from their breeding place 

 at most. Miss Ludlow's record of the European dot'salis from Cali- 

 fornia '' probably refers to this species or to currieL It is not prob- 

 able that any European mosquito occurs in North America, except the 

 domesticated Culex pipiens and perhaps the malarial Anoplieles.

 sent to Professor Smith and to me were invariably determined as curriei {quaylel), 

 as we all supposed squamiger should have a very distinct larva. See Grossbeck, Can.
