NO. 151(1. MOSQUITOES FROM COAST OF CALIFORNIA —DYAR. 123 



CULISETA INORNATUS Williston. 



This species has been g'oino- under the name of con-sohrlnns^ \n\t I 

 am unable to agree with this identitication of Robineau-Desvoidy's 

 name, and use Williston's instead. The species was scarce, but was 

 ])red from larvae at Laguna, Eureka, and Sisson, California, and com- 

 monly at Klamath Falls, Oregon. At the latter place pairs were 

 ol)served in coifu, I'esting on the underside of some boards over water. 

 The}' were captured and did not separate even in the cyanide bottle. 



CULISETA MACCRACKENiE Dyar and Knab. 



This species has been taken at San Francisco (Miss McCracken) 

 and Eureka (H. S. Barl)er), but I was not so fortunate as to meet with 

 it. The larva is unknown to me. It is the species formerly identified 

 with the European annulatus Meigen. 



CULEX TARSALIS Coquillett. 



A common species, but not troublesome, as the adults never bite by 

 day and are sluggish in their attack even at night. Moreover, the 

 species does not breed in water receptacles near dwellings, such as 

 rain ])arrels. Larva; occurred in marshes and puddles, in river beds, 

 and even in grass in the edges of lakes. Brackish water, when stand- 

 ing permanently near the sea, was also a breeding place. The species 

 extends to the north through Oregon, Washington, and British 

 Columbia, as well as east to the Mississippi Valley. 



CULEX STIGMATOSOMA, new species. 



Head with black and golden scales })ehind, side of occiput pale gray; 

 eyes narrowly white behind; proboscis black with a white band a little 

 beyond the middle; palpi and antenna^ black. Thorax bronzy brown 

 with longitudinal striation, a round whitish spot on each side at the 

 middle, from which an ol)solete pale stripe runs backward; sides 

 sparsely pale yellowish scaled, the integument greenish at the bases of 

 the legs. Legs black, the femora whitish below, no white lines above; 

 tibiiv black with a small white apex and a long whitish line within; 

 tarsi black, a white ring at base and apex of each joint, including the 

 terminal joint. Abdomen black, with broad white bands on the bases 

 of the segments al)Ove, whitish scaled l>elow with a row of median 

 segmentar}' round diffuse black spots. Wing scales narrow, entirely 

 black, not forming spots. 



Three hundred and twenty-two specimens, Pasadena, California, 

 larva? in a pond in a lawn; Laguna, larviB in a well hole by the edge 

 of a lake; San Diego, in an old water vat on a wharf; Sweetwater 

 Junction, in pools in a stream l)ed; San Luis Obispo, in a pool in a 

 rocky canyon (A. N. Caudell); Avalon, Santa Catalina Island, in a rain-
