single larva may spoil several young fruits before reaching ma- 
turity ; one was observed to destroy six out of eight young quinces 
on a tree. 
Altho the green fruit-worms were introduced to Illinois fruit 
growers as early as 1870 by Dr. C. V. Riley, who in the American 
Entoi]iologist and Botanist noted the identifications of specimens 
for three Illinois growers, they have not as yet received the atten- 
tion they merit, considering that they have repeatedly damaged the 
apple crop of Illinois to a considerable degree.

Mr. A. J. Dunlap, of Olney, reported to us that several varieties 
in his apple orchards had suffered to a great extent, the Akin being 
especially badly damaged; Mr. Geo. W. Emerick, of Sumner, who 
has 100 acres in apples, stated that they were very common in his 
orchards, damaging his crop to the extent of about $1,000, as many 
as 7 percent of the apples on some trees having been badly eaten ; 
and Hon. H. INI. Dunlap reported considerable loss, so much that 
he was planning additional spraying on ibis account. In the Clay 
county experimental orchards of the State Experiment Station great 
damage was caused the same season by these worms. 
In many cases these worms have proved on breeding to belong 
to the genus Xylina. Our fullest and most satisfactory account of
