NO. 1516. MOSQUITOES FROM COAST OF CALIFORNIA— DYAR. 125 



Avalon, Santa Catalina Island, in a rain-water barrel; Los Angeles, 

 in water in a cellar; San Luis Obispo, in an old tin can. No speci- 

 mens were taken any farther north. 



CULEX TERRITANS Walker. 



The larvte occurred sparinuly in permanent water, when clear and 

 cold; no adults were taken except those bred; Pasadena, in a wooden 

 water box in the arroyo, at Devil's Gate; in a large clear pool behind 

 a clay dam in the arroyo at the Ostrich Farm; Sisson, in a springy, 

 grassy meadow and in roadside puddles. 



AEDES VARIPALPUS Coquillett. 



The larvte occurred in holes in live-oak trees in the arroyo at Pasa- 

 dena. Farther north, where the oak does not grow, the species seems 

 addicted to the alder; the conifers do not form holes suitable for the 

 larva? to ))reed in. Adults were taken at Dunsnmir, California; Ash- 

 ford, Oregon; Seattle, Washington; Vancouver, Victoria, Nanaimo, 

 and Wellington, British Columbia. Unlike any other North Ameri- 

 can species (except Stegomyia calopus Meigen), the males are attracted 

 to the person as well as the females. While they can not bite, they 

 occasionall}' alight, and several were so taken, supposed at tirst to be 

 females about to bite. While sitting in the woods near Victoria, 

 British Columbia, the writer observed a small swarm of males which 

 gathered before him and continued to dance, one occasionally alight- 

 ing for an instant, as long as he remained there. During this time 

 two females came to bite and each was immediately seized by a male, 

 the pair flying ott' in a downward direction in copulation, which lasted 

 apparently but a few seconds. 



AEDES SPENCERI Theobald. 



Recorded from California by Miss Ludlow." The species ranges 

 with curriei in the North and should occur in California. I have not 

 taken any specimens. The larva has never l)een found. 



AEDES SYLVESTRIS Theobald. 



Quayle gives this as occurring in California,^ and no doubt with cor- 

 rectness, as it is known to me from Arizona. It is probably the species 

 that forms the pre}' of Psorophora ciliata as larvae.
