of the cucumber. One with experience 
can readily distinguish by the use of an 
ordinary hand glass. He will then see on 
the underside of the leaf the violet spores 
and spore-bearing threads of the mildew 
fungus. The melons which are unripened 
upon the vines when attacked by mildew 
are practically worthless and for this rea- 
son large losses are usually incurred. The 
treatment is by Bordeaux mixture. 
Muskmelon Leaf Blight 
Alternaria sp. 
Is a disease more or less peculiar to 
the muskmelon, although the fungus 
which causes it has also been found upon 
cucumber leaves. The leaf blight causes 
rather large dead areas in the leaves 
which are usually distinguished from 
those of downy mildew by their larger 
size and the tendency of the central por- 
tion to break out. The prevention of 
muskmelon leaf blight is by no means 
an easy matter, requiring of itself great 
thoroughness and carefulness in the ap- 
plication of the Bordeaux mixture and 
also requiring that the downy mildew 
shall be watched during the same period. 
For this reason earlier sprayings, if made 
before August ist, should be repeated at 
fortnightly intervals, while those after 
August 1st should be at weekly or 10-day 
intervals. Melon growers have succeeded 
by following these lines, while others 
who were less thorough were less success- 
ful, or failed entirely. The treatment is 
recommended with confidence. 
Wilt 
Muskmelon wilts are the same in gen- 
eral character as those described for the 
cucumber. Not only the bacterial wilt 
disease but the wilt due to fusarium has 
developed upon muskmelons in some 
parts. The symptoms are the same as 
for cucumbers, namely: sudden wilting as 
from lack of water, followed by dying. 
Gather and burn infected vines and 
practice rotation. 
Root Rot 
Rhizoctonia 
The root diseases accompanied by rot- 
ting of the rootlets and induced by the 
sterile fungus of lettuce rosette is also 
found on greenhouse muskmelons. This 
755 
is liable to be the case wheré these fol- 
low diseased crops of lettuce. The pre- 
vention is thorough soil treatment.

CANTALOUP PESTS 
Cantaloup Fly 
EHuxesta notata Wield., Family Ortalidae 
General Appearance 
The adult flies are slightly over one- 
eighth of an inch long, beautiful metallic 
green in color with eyes dark brown. The 
wings are transparent with a distinct 
black spot near the middle of the front 
margin and a similar spot near the tip 
of each. The maggots vary from white 
to dusky brown, the blunt end being 
often darker than the rest of the body. 
They are about one-fourth of an inch 
long when fully matured. 
Life History 
The eggs are laid in the tissues of in- 
jured or damaged fruits and vegetables 
and while the maggots work principally 
upon such tissue they are often found 
in sound and living portions and occa- 
sionally in apparently uninjured fruits. 
The pupae are found in the decayed hosts 
or in the soil, the adults emerging in a 
very short time. Due to the peculiar 
habits of the larvae, they have often been 
mistaken for the maggots of the true 
fruit flies of the family Yrypetidae and 
have been the occasion of great alarm.

White-Lined Sphinx 
Celerio lineata Fab., Family Sphingidae 
Deilephila lineata Fab. 
General Appearance 
This is a very common insect. The 
adult moths are quite large, having a 
wing expanse of nearly three and one- 
half inches. The fore wings are green 
with broad brown bands on the front and 
apical margins and in the middle of each. 
The veins are white. The hind wings 
are very small, dark brown with a wide 
lighter band across the middie of each. 
The thorax is grayish with distinct white
