182 AMERICAN MIDLAND NATURALIST. 
appeared in Virginia. It was found, however, that it had 
been introduced into Virginia from New Jersey in 1891. (Bull. 
No. 3, U. S. Bureau of Entomology, U. S. Dept. of Agricul- 
ture.) The same year it was introduced into Washington 
County, Indiana, on apple trees shipped from New Jersey, 
but it was not discovered until 1894. It has since appeared in 
many parts of the State, but its further spread is being check- 
ed by rigid inspection. 
imported elm leaf beetle, Galerucella luteola, 
was brought to this country in 1834, but was con- 
fined to the east until 1890, when it was carried 
to Kentucky. - Ten years later it was introduced into 
Indiana at Tobacco Landing, Harrison County. It spread 
very slowly but was carried on trees or by wagons to Eliza- 
eth and New Middleton, and has now spread over most of 
the southeastern third of that County. (See map.) It is not 
active in flight and hence spreads very slowly, except where 
it is carried. It crawls a great deal, however, and hence is 
sometimes carried by wagon. 
ot every species of insect has increased. No doubt wood 
boring beetles, and forest insects of many kinds have de- 
- creased and some have even been exterminated. But we know 
these so little that it is not possible to point out many in- 
stances. Eie hs the following species are known to have 
. .The blue-eyed grayling, Cercyonis alope, appears to be 
diminishing. Scudder (’86) included the entire State in its 
range. Blatchley ('91) said that it was not found south of 
Wabash County. Ellis says that it is now more scarce than 
ever, being restricted to the three northern tiers of counties. 
The food plants are wild grasses and sedges. The butterfly 
frequents swampy woodlands and is being exterminated by 
the draining and pasturing of these. 
Hornets, yellow jackets and many wasps are less numer- 
ous than formerly. They are destroyed by man at every op- 
portunity because of the painful wounds which they inflict. 
Since they live in colonies, the destruction of a large number 
is an easy matter. Cultivation of the soil also destroys yellow 
jackets and other burrowing species.

mon inhabitant of the forest. The larvae live in decaying
