New Species.

In September, 1901, I began to look for individuals of the 

 mosquito genus Anopheles in the vicinity of Stanford Univer- 

 sity. The University is situated near the base of the San 

 Francisco peninsula, which is thirty-five miles long and 

 about twenty-five miles broad at its base, and extends north 

 and south between the Pacific Ocean and a long southern arm 

 of the Bay of San Francisco. Running its full length about 

 midway between ocean and bay is the Santa Cruz (or Sierra 

 Morena) Range of mountains, the altitude of the crest being 

 about 2,500 feet in the south, and onh- slowly decreasing in 

 altitude toward the north. My collecting ground, in the vicin- 

 ity of the villages of Menlo Park, Palo Alto, May field and of 

 the University, has been on the bay side of these mountains in 

 the southern or basal portion of the peninsula. 



The locality is not a pialarial region. Several cases of 

 malaria have been reported by resident physicians, but it 

 appears, upon inquiry, that each patient so reported had either 

 recently been away from the town or had recently come from 

 a distance. 



The various lakes, pools, streams and troughs in the neigh- 

 borhood were visited continuously from September 5 to Decem- 

 ber I, 1901, and again from March i to May 10, 1902, at inter- 

 vals of a week or two. 



Anopheles puyictipennis and Anopheles niaculipennis were 

 found at various times and in various places, A. maculipennis
