PLUM. FRUIT. 
69. Saddled leaf-hopper, Bythoscopus clitellarius, Say. (Homoptera. Tet- 
tigoniidae.) 
A small cylindrical slightly tapering leaf-hopper, 0.20 long, 
black or dark brown, with a bright sulphur-yellow spot like a 
saddle upon the middle of its back, a band forward of this and 
also the head and under side pale yellow, the forehead with two 
black dots. This probably punctures and sucks the juices of the 
green succulent twigs as well as the leaves, but I have particu¬ 
larly noticed it standing upon the fruit stems with its beak inserted 
therein, extracting the tluids which should go to swell and perfect 
the fruit. And it would thus seem that these leaf-hoppers, like 
many other insects, are actuated by a spirit of pure malevolence 
in making their attack upon that part of the plant where they 
will do us the most injury, when they might nourish themselves 
equally as well in places where their harm would be slight. 
AFFECTING THE FRUIT. 
70. Plum weevil, or Curculio, Conotrachelus Nenuphar, Hcrbst. (Cole- 
optcra. Ourculionid®.) 
Making a small crescent-shaped incision upon the side of the 
young fruit and dropping an egg therein, from which comes a 
small white footless worm or grub which bores in the fruit, causing 
it to become diseased and gummy and to drop from the tree, the 
worm when full grown entering the ground and in three or four 
weeks coming out in its perfect state, when it is a short thick rough 
beetle, shaped somewhat like a pear, and with a long snout like 
an elephant’s trunk hanging down in front, its color dark brown 
with a bruad white or yellow band on the hind part of the wing 
covers, and small spots of black, white and yellow. Length 0.15 
to 0.28. For the winter residence of this weevil, see insects of 
] ear limbs, p. 349. See Harris’s Treatise, p. 66.
