The collecting points were all within four miles north or 

 south of the University, and within six and a half miles of 

 each other. Felt Lake, the farthest point in one direction, is 

 between 200 and 325 feet above sea level. It is a reservoir 

 that lowers during the summer months below its outlet, but 

 does not dry out entirely. Flood Lake, the farthest point in 

 the opposite direction, is within a half-mile or so of tidewater 

 and usually dries out during the summer months. A. maadi- 

 pennis was found in both. The troughs visited contain water 

 all the year round. The creeks frequently dry out during the 

 summer months. The tank overflow has been permanent. 

 Frenchman's Lake is a small reservoir that dries out. 



At no time or place were the larvae of either species very 

 abundant. No adults were seen flying except on the evening 

 of April 23, 1902, in the neighborhood of Francisquito Creek, 

 in the willows and alders, when they were quite abundant. 



The larvae were, with one exception, found in comparatively 

 Clearwater. On October 6, 1901, A. pundipeniiis v{2lS found 

 in the creek, in very foul water. 



On September 29th, 1901, a few full-sized larvae and several 

 pupae were brought to the laboratory from Felt Lake. A few 

 days later the adults issued, and proved to be an unidentified 

 species. 



This species was found continuously in small numbers at 

 Felt Lake from October 5th to November 8th, 1901, invaria- 

 bly in companj' with Dixa, occasionallj" in company' with A. 

 macuUpetinis , and, on November 8th, with Cidex eggs that 

 later development proved to be those of a new species, Culex 

 keUogii Th.., recently described by Theobald (^Canadian Ento- 

 mologist, vol. XXXV, p. 211, August, '03). 



In general appearance and habits, the larva of this new Ano- 

 pheles is not unlike that of maculipejinis, as described by How- 

 ard (" Mosquitoes," p. 103 et seg.), and in greater detail by 

 Nuttall ( ' ' Studies in Relation to Malaria, ' ' /our. of Hygiene, 

 vol. 1, 1900, p. 51 et seg.) 



In detail we find, in a fully-grown larva of this species, on 

 the ventral surface of the thorax, three sets of lobes, bearing 

 characteristic hairs : (a) a pair on the prothoracic part of the
