they come back in the autumn for the

Their eyes bulge out, their skin drops

from other parts of the world have been
induced to occ1py the highest part of the

It has been discovered that there are

Of them do not convey malaria. DR.. Rom

has been associated with DR.. Manson in
studying the pests. devoted himself par
ticularly 10 the species Culex and Ano-
pheles After little study he found that
they could be distinguished by their
heads and their limbs. He could even
tell the male Culex from the female find
ing that the female alone lives on blood
while the male eats nothing but vege-
table food. The female is the real enemy
OF the human race The small head OF
the female has a sharp. long sting.
What is visible 10 the naked eye and is
generally called the sting is really the
sheath Of the instrument. This opens.
and lets the sting protrude between the
two lips NJ the proper time. Around
this sting are from four to six little avis
which are used for extending the wound
after the puncture is made. In the male
Culex the feelers. or palpi. are longer
than the proboscis, and are overed with
thick. long hairs.
In the Anopheles mosquito the feelers
Of both male and female are OF the same
length. and neither shorter nor longer
than the pro5osCis. In the female, how
ever, the feeiers are 50 close 10 the pro
boscis that it looks as Il the latter were
