Scientific Description of the cuIex, The
Stesomyia and the Anopheles.

Dr. G. w Drake, resident physician
at the Monteagle Assembly at Mout
eagle, Tenn, writing to the Nashville
Banner. has the following interesting
article on this timely subject.
"Culex is the ordinary house mos
quito. They are the most numerous
and widely distributed They have NJ
stripes on their legs, w.ngs or body
Their bodies are clumsy, and when Al
rest on the wall their feet cleave to-
It, their bodies being parallel to the
surface Of the wall They sleep in
the daytime and bite at night
Stegomyia presents some resem-
blance to culex Its form and posi-
ton when resting en- tle wall are like
those of cnlex, but ii is striped and
Il wen known as the brindled or tiger
mosquito Stegomyia often bites dur

bite Of stegomyia conveys the infec-
ton OF yellow fever. Stegomyia will
not live longer than five days ii de

Culex and stegomyia are the kinds

bite Of stegomyia and you prevent this

bite of anopheles and you prevent the
infection Of malaria To prevent the
bite of mosquitoes use nets and wire
