These newfood plants being always at hand during the season when thebug lays its eggs and the young are growing and occurring invastly greater quantity, of course gave the insect advantages forrapid increase. The loose soil about the roots of these culti-vated plants, too, more nearly met the requirements necessaryfor the work of the young than was to be found upon unculti-vated grounds. The Chinch-bug was first scientifically described by Say, in the year 1831, from a single specimen capturedin eastern Virginia. He called it Lygceus leiicopferiis. Soonafter this, and within a few years, its range in injurious numbersbegan to Aviden, it having made its appearance in grain fields indifferent localities west of the Alleghany mountains.
