REPORT OF THE ENTOMOLOGIST. 89 
the eggs in May and June, by washing the trunks and branches of 
infested trees with two parts of soft soap to eight parts 
of water, adding lime enough to give it the consist- 
ence of whitewash; or thoroughly syringing with 
strong tobacco-water and soap-suds. 
The eggs of the chinch-bug, Rhyparochromus (Mi- 
eropus) leucopterus, (Say,) an insect which has done 
great damage to grain in certain localities, are de- 
posited in the ground to the number of about five hundred by one 
female. The young larve are hatched under the earth, having been 
found in great numbers at a depth of an inch or more, Fig. 59. 
and are at first wingless, and of a bright red color. .\~ 4 
They puncture, and apparently poison, in both larva VEY 
and pupa as well as perfect states, the terminal shoots, /= 
buds, and the most succulent parts of growing plants 
of grain, grass, maize, potatoes, and other vegetables, 
but do not attack woody plants. There are two broods 
aunuually and perhaps three in the south, the last brood IR 
hybernating in the perfect state under leaves, or sheltered under stones, 
earth, &c. The insects are most destructive in hot, dry summers, and 
heavy rains are said to destroy them. Early grain is most likely to es- 
cape their ravages. The remedies recommended are rolling the ground 
where the young insects are, if practicable; burning up all the dead 
vegetation and dry rubbish along fences will materially lessen their 
numbers the next season; when congregated on certain spots, dry straw, 
spread over the place and burned, will destroy numbers; gas lime sown 
broadcast over intested fields, at the rate of six or seven bushels to the 
acre, is also recommended; or dropping a handful of gas lime on each 
hill of corn, when infested. According to Dr. Shimer, coal-tar is of no 
use as aremedy. Quails are said to feed greedily upon the insects, and 
should therefore be protected. 
The common squash bug, Coreus (Gonocerus) tristis, (Degeer,) has been 
extremely injurious to«the squash family in many 
parts of the Middle States, injuring the plants in 
larva, pupa, and perfect states, by congregating 
in great numbers around the stem near the 
ground, or on the leaves, and sucking out the 
sap by means of their strong béaks. The eggs 
of this insect are deposited in little patches fast- 
ened to the under-side of the leaves in June and 
July. It is stated, however, that all the eggs 
are not deposited at the same time. The young 
insects live in families, puncturing the leaves and stem, and draining 
the sap trom the plant. The perfect insects hybernate in crevices of 
walls and fences, and have been found in Maryland in midwinter under 
the bark of rotting trees, from whence they come out in summer to de- 
posit their eggs for the first generation. One of the remedies recom- 
mended is to remove all the earth from the roots as far as they will bear, 
and fill up with a mixture of dry ashes and salt, which will prevent the 
insects from burrowing near the root. Another remedy is to trim off 
the under leaves early in the season, laying them in the evening under 
and close to the plant; the insects hiding under them can be found and 
destroyed in the morning. It has been suggested to lay pieces of boards 
along the rows, a little raised from the ground by small stones. During 
the night the insects will congregate under the trap; the boards and 
leaves, however, should be examined very early in the morning, 
Fig. 60.
