404 ENTOMOLOGY 
ing state entomologist, a report in the interests of horticulture 
an accurate, sagacious and altogether excellent piece of ori- 
ginal work. Like many cther economic entomologists he was 
a prolific writer for the agricultural press and his contribu- 
tions, numbering about four hundred, were in the highest 
degree scientific and practical. 
Walsh was succeeded by Dr. William LeBaron, who pub- 
lished (1871 to 1874) four able reports of great practical 
value. In the words of Dr. Howard, “ He records in his first 
report the first successful experiment in the transportation of 
parasites of an injurious species from one locality to another, 
and in his second report recommended the use of Paris green 
against the canker worm on apple trees, the legitimate outcome 
from which has been the extensive use of the same substance 
against the codling moth, which may safely be called one of 
the great discoveries in economic entomology of late years.” 
Following LeBaron as state entomologist, Rev. Cyrus 
Thomas and his assistants, G. H. French and D. W. Coquillett, 
produced a creditable series of six reports (1875 to 1880) as 
part of a projected manual of the economic entomology of 
Illinois. 
Since 1882, Prof. Stephen A. Forbes has fulfilled the duties 
of state entomologist in the most efficient manner. Thor- 
oughly scientific, with a broad view and a clear insight into 
the agricultural needs of the state, his authoritative and schol- 
arly works upon economic entomology rank with those of the 
highest value. Of the twelve reports issued thus far by Dr. 
Forbes, those dealing with the chinch bug, San José scale, corn 
insects and sugar beet insects are especially noteworthy. 
Missouri.—Appointed in 1868, Prof. Charles V. Riley pub- 
lished. (1869 to 1877) nine reports as state entomologist. To 
quote Dr. Howard, “ They are monuments to the state of Mis- 
sourl, and more especially to the man who wrote them. They 
are original, practical and scientific. . . . They may be said to 
have formed the basis for the new economic entomology of 
the world.” Riley’s subsequent work will presently be spoken
