The data for the mosquito catch under buildings during the 
daytime shows that 33.42% of the total catch is made from 
6:30. a. moto 8:00 'a.. mm. Several “tests were made tommonre 
whether the color of the ground had any effect on numbers. 
White and black ground were used, and the day’s catch of the 
two was taken as 100%. Of this white ground yielded 39.33% 
and black ground 60.67%. The question of color of barracks, 
color of interior, color under houses, location of doors, of 
windows, etc., have greater importance in the reduction of 
the numbers of mosquitos than is at first believable, and more 
definite studies along these lines are needed. 
3. Securing Food and Eating. 
To describe adequately the voracity of the female tarst- 
maculata or teniorhynchus is to attempt something bordering 
on the impossible. For indeed language falls short when one 
tries to narrate what he has witnessed. No matter the time 
of the day or night, just as soon as one left the boat and entered 
the jungle of the marsh, hundreds of hungry mosquitos flew 
forth to warmly welcome the intruder. And if the intruder 
had come just as dusk appeared, the welcome he received was 
simply tormenting. Despite all efforts to drive these mosquitos 
away, he would carry with him no few bites. Laboratory 
tests showed these two species ready to suck blood when but 
eighteen hours of age. 
There is preference shown to leather leggings and khaki 
cloth. Since these have a definite odor, probably odor as 
well as color are the attractive features. Never was there 
noted an indisposition to eat, and satiation bordered always on 
gluttony. The proboscis, aided by the palpi, probed assidu- 
ously khaki, leather, etc., very often succeeding through cloth. 
When the proboscis enters the flesh, very little pain is felt, 
i. e., not nearly so much as some Culex can produce. Fre- 
quently the beak is withdrawn and reinserted with increased 
vigor. Not infrequently females would so gorge themselves 
with blood that the hind feet could no longer sustain the weight. 
The normal position of the mosquito is with the body at forty- 
five degrees, but when feeding, this position of the mosquito on 
the person is not of such great importance. Mosquitos were 
seen hanging from the under side of the arm. When the
