PLANT-BUGS INJURIOUS TO COTTON BOLLS. 
even when in the same fields parasitized specimens of other genera 
are numerous. 
A Proctotrypid parasite, Trissolcus euschisti Ashm., has been 
recorded as having been reared from the eggs of EuscMstus servus in 
Kansas. It has been stated in connection with the subject of egg 
parasites of the conchuela that the important agent in checking the 
multiplication of that species, Telenomus ashmeadi Morrill, in the 
laboratory does not hesitate to oviposit in the eggs of EuscMstus 
servus and that adult parasites have duly emerged in such cases. 
This parasite is not at present known to occur in cotton-growing 
sections where the brown cotton-bug is found in abundance, but 
doubtless other Proctotrypids have more or less influence on the rate 
of multiplication of this bug. 
PENTATOMID BUGS OF THE GENUS NEZARA. 
THE GREEN SOLDIER-BUG. 
(Nezara hilar is Say.) 
The frequent injuries by the green soldier-bug (PL I, fig. 3; text figs. 
14, 15) to various crops and its wide distribution throughout the United 
States have resulted in its be- 
ing one of the most generally 
known plant-bugs. A good 
general historical account of 
the species has been given by 
Sanderson in a previous bul- 
letin of this Bureau. The 
bug was first recognized as a 
cotton pest in 1855, Townend 
Glover b referring to its abun- 
dance on cotton in Florida 
and briefly describing the na- 
ture of its injury, evidently 
misidentifying it specifically. 
It was figured in 1878 by the 
same author with insects 
injurious to cotton under the name Nezara pennsylvanicus . This 
error in identification has been indicated by Comstock. d A corre- 
spondent of the Division of Entomology e reported damage to cotton in 
Florida in 1890 by the green soldier-bug, and Sanderson (1. c.) briefly 
mentions damage to cotton in Texas from this insect in 1903 and 1904.
