BUFORD. 633 BUG. He afterwards engaged in iron-manufacturing and banking at Peoria. III., and became president of the Rock Island and Peoria Railroad. In the Civil War he was first a colonel of volunteers and then a brigadier-general, took part in the sieges of Corinth and Vicksburg, and in )S6.^ was brevetted major-general of volunteers. Gen- eral Buford was Government inspector of the Union Pacific Railroad from 18G7 to 1869 and a special commissioner of Indian affairs in 1867-68. BUG, boog. Two rivers of Russia. The first, a tributary of the Vistula, rises in Galicia. Austria-Hungary, and entering Russia, flows at first north, along the eastern borders of Poland, and then west, and joins the Vistula at the fortress of Xovogeorgieosk. after a course of over 450 miles (Map: Russia, B 4). It is navigable for over .300 miles, and is of great im- portance to the lumber trade of Russia. It is connected by canals with the Dnieper and the for piercing and sucking. Nearly all bugs sub- sist on the juices of plants, a few part.ake of animal juices alone, and sevei-al of both animal and vegetable lluids; hence, economically, the order is very injurious. A few forms are pre- daceous and hence helpful. Certain others, such as the cochineal and lac-dye insects, and their secretions, such as china-wax and shellac, are articles of considerable commercial importance. -Many bugs secrete a substance characteristically pungent, penetrating, and often having dis- agreeable smell and taste. The metamorphosis of bugs is incomplete — i.e. they do not transform completely at once: and the parasitic forms are wingless. Some of the species are very large, certain aquatic ones reaching a length of 12 centimeters. A loathsome, long - known, and widespread pest of man is the bedbug (q.v. ). In Chile a very large bug hides in the thatch of bouses, and, like the bedbug, comes out at night TYPICAL Bros AND 8TBUCTUBE. 1. Adult Squash-Bng Mna^a arroigrera). 3.

The second river, the ancient Eypanin, or Bogus, whence the name, rises in the southern part of Volhynia. and flows in a southeastern direction through the governments of Podolia and Kherson, emptying into the Black Sea near Nikolayev, where it forms a wide estuary con- nected with the DnieiHT Liman (Map: Russia, D 5). Its total length is about .500 miles, and it is navigable for small craft as far as Voz- nesensk, while larger steamers can ascend only to Nikolayev. Its chief tributary is the Ingul. BUG (Welsh bwy, spectre. Corn, biicca, bug- bear; cf. Lith. baugus, terrific). The common name applied to the various members of the order Hem iptera (Ok. ^u(-, Acnii-, half -{- -repuv, pteron, wing), so named because the basal half of the wing in many of the forms is thickened like the wing-covers of beetles, while the distal half is membranous and wing-like. The mouth parts are in the form of a beak, and are fitted to suck blood. In England there is found on the birch-tree a bug that has the rare habit among insects of caring for its young. Among all the bugs injurious to agriculture, the chinch- bug (q.v.) (Blissus leucopterus) ranks first in the United States; and it is in the Missis- sippi Valley that it does the most harm, de- stroying entire crops of wheat, oats, and Indian corn, especially during dry, warm summers. The squash-bugs destroy squash and pump- kin vines. t)ther bugs feed on cabbage, radishes, and turnips. The true lice, both of man and beast, are bugs ; so also are the cicadas, which include the seventeen-year locust. Cer- tain plant-sucking bugs cover themselves in their immature stages with a mass of foam, which is commonly known as 'frog-spittle.' To the bugs belong the aphids, plant-lice which prey on the root, stem, or leaf of all sorts of plants. Closely related to the latter are the scaly bug^
