CONE. 264 CONE-SHELL. the cone. A cone whose base is a circle is called a circular cone. If the vertex is on a perpen- dicular to the base of a circular oono, through its centre, the cone is called a right circular cone. A right circular cone may be generated by rotat- ing a right-angled triangle about one of its per- pendicular sides. The line from the vertex to the centre of the base is called the axis. If the axis makes with the l)ase an angle other than 00°, the cone is called oblique. If a plane cuts a cone between the vertex and the base, the cone is said to be truncated ; if the cutting plane is parallel to the base, the lower part is called a frustum of the cone, the section made by the cutting plane being called the upper base. Three curves, called conic sections (q.v. ), may be formed by planes cutting a right circular cone at various angles to the base. CONE, IN Botany. See Conifer.e. CONE, Orello (1835—).

A bug of the predatory family Ivcduviida'; specifically Cono- rhiniis sanr/nisuria, called 'giant bedbug' in the southern United States, where it is a pest in houses. It is three-quarters of an inch long, black with red patches, or spots, on the sides of the thorax, at the base and apex of the wing-covers, and bands on the sides of the abdomen. The young much resemble large bedbugs (to which they are allied), and all ages are fierce biters and blood-suckers, preying upon insects and flying into houses at night and attacking sleeping per- sons and animals. The kissing bug seems to breed in the nests of mice, and is prevalent from the central Mississippi Valley to the tropics. The name 'assassin bugs' has been given to the whole family by Comstock, because of their cannibalism and rapacity ; and to certain s|)ecies, especially Mclanolcstes picipes and Rediivius personatus, which were especially abundant in the Eastern States during the summer of 1898, was due the 'kissing-bug* excitement, busily fostered by the newspapers. Of the two 'kissing bugs' abot men- tioned, the latter, according to Howard, is a cos- mopolitan form which, in the Northern States, is found in basements and cellars of dirty houses, and preys upon bedbugs and cockroaches. When immature it covers itself with dust and ])resents a very odd appearance. The 'thread-legged' bugs of the family Emesidse, which rob spiders of their prey, are near relatives. CONEPATE, ko'ne-pat (Nahuatl nepatla. subterranean dwelling) . The name in Mexico of the large white-backed skunk {Conepatus mapu- rito) , called in South America 'mapurito.' See Skunk. CONE-SHELL. The popular name of a genus (Conus) and family (Ctmidie) of gastropod mol- lusks, of the order Streptoncura; having a shell of remarkably regular conical form ; the spire on the base of the cone, and sometimes rising from it to a sharp point, sometimes almost flat; the aperture narrow and straight, without protuber- ance or fold, extending from the base of the cone to its apex. The head of the animal has a pro- boscis capable of much extension ; the mantle is scanty and narrow, forming an elongated siphon in front ; the shell is covered with an epidermis. These mollusks are carnivorous; they inhabit A CONE WALKING TOWARD THE LEFT.
