It hAs now been prS11g weH estab-

which are found in the bd Of human
victims Of so-calied ~ Hal" diseases
are also found in go mosquitoes.
And 1t appears to nag been Semon-
strated that certain s&1ges Of the de-
velopment OF these microbes occur out
side the human body. It il yet to be
proved that the mosquito Affords the
only other domicile required for this
part Of the parasites career. But just
now that insect il the culy living crea-
ture against which comphcity in the

In . recent address In this city DIR.
L. O. Howard, chief entomologist ofthe
agricultural department in Washing-
ton, pointed out several differences be-
tween the two. First. as to their wings.
Those Of the culex are practically with
out any color markings. Those Of the
anoIheles bear dark, irregular patches,
which are not so well defined AZ those
Of butterfly, but which are easily
recognized II the two insects are
placed side by side. Then there are
their feelers, or "palpi." These are two
In number and stick out forward from
the head, one on, each side Of the pro-
boscis. Those Of the culex are short
and insignifcaht, while the palpi Of the
anopheles are nearly as long as the
proboscis. Thirdly, the two mosquitoes
have different way Of resting on the
wall Of room when quiet. The body
Of the culex is parallel with the wall,
whereas that Of the. anopheles sticks
out at an angle. If he is on the ceiling
his body will seem to stick out at
right angle. The hum OF the culex is
little shriller than the note of the
anopheies. The difference in pitch IL
about equal to four tones Of the musi-
cal scale. Finally. It appears that the
anopheles Is chiefly active at night and
10 given to repose by day. Other points
of d4ssimilarity have been observed in
the eggs, larvae and pupae. But these
need not be dwelt on here. It would
require an expert to detect them. The
means already described, and especial.
ly the first three, will be found the
readiest and most convenient for dis
tinguishing the two insects. And a
study Of mosquitoes from this point Of
view is likely to prove fascinating
and profitable pursuit to good many
young people this summer.
