which A. quadrimaxmlatus is breeding pretty generally this ques¬ 
tion can be determined. If after the pond is filled—say, the second 
year—the differential breeding habits of these two species as to 
locality are the same as observed at this place and at the Coosa pool, 
it will be decided in the affirmative. Examination of the surrounding 
country bejmnd the possible influence of the pond, to determine 
the production of A. quadrimaculatus therein, should also throw 
light on the subject. The observations at Eau Clair, not made for 
this purpose, and at Shelby are on this line. Possibly the presence 
of the small number (only two) of A. quadrinwculatus in the drift in 
Cedar Creek on the Coosa River may mean that they were from side 
pools or small marshes very far from the pond and were washed down 
on floatage. This creek was very large and long and with bold banks, 
and this could happen. 
It is well known how Aedes calopus accommodates herself to avail¬ 
able breeding places. Remove artificial containers, gutters, etc., and 
she takes the axils of leaves and other out-of-the-way places. Put 
out a few buckets of water—“trap breeding places”—and the eggs 
will be deposited in them to the exclusion of the out-of-the-way and 
presumably less eligible places. It is then in accordance with 
analogy that A. quadrimuculatus might also show a similar adapti- 
bility. 1 
ANOPHELES IN HOUSES. 
The same facts were observed as to the greater frequency of A. 
quadrimaculatus in residences as compared with A. punctipennis , as 
have been given for the Alabama survey, but no attempt was made, 
as was done there, to get quantitative data. 2 
DISTANCE OF FLIGHT OF A. QUADRIMACULATUS. 
Some observations on the distance of flight 3 of A. quadrimaculatus 
were made during this survey. They are not sufficient as vet to pub¬ 
lish, but will be used subsequently. Obviously, the breeding condi¬ 
tions which we believe we found existing in the neighborhood of these 
ponds are ideal for the determination of the distance of flight of this 
species of Anopheles. If this species breeds only in the pond and

Indies,” Howard, Dyar, and Knab, p. 221. 
2 We note that at Mr. Cheatham’s—about one-half of a mile from the Stevens Creek 
pond and 100 yards from a stream breeding A. punctipennis —68 A. quadrimaculatus were 
counted in one bedroom, and “ thorough search not made.” No A. punctipennis noted. In 
the same room later “ 30 A. quadrimaculatus taken from wall, larger number on ceiling.” 
No A. punctipennis noted. At Mr. Mayers’s—about one-fourth mile from the Parr Shoals 
pond, a bight breeding profusely at the time—“ many A. quadrimaculatus taken under the 
house.” The house is screened, “No A. punctipennis seen at the house,” yet there was 
a place producing the latter species profusely closer than the pond. This comparative 
scarcity of A. punctipennis in residences was, during the summer, observed whenever 
examination was made.
