A Proctotrypid parasite, Trissolcus euscTiisti Ashm., has been recorded as having been reared from the eggs of Euschistus 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 multiphcation of that species, Telenomus ashmeadi Morrill, in the laboratory does not hesitate to oviposit in the eggs of Euschistus 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.) HISTORY. 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 ^ referring to its abun- dance on cotton in Florida and briefiy 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.^ A corre- spondent of the Division of Entomology^ 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. a Bui. 57, Bur.
