KATYDID. Under, the heading Catydid, was given something in relation to that class of insects, except the locusts proper,' which go under the general name Grasshopper. The Katydids belong to the order Orthoptera, which includes the earwigs, grasshoppers, true locusts, crickets, etc. Dr. Riley, in his sixth Missouri Report, says: We have in this country four Katy dids that are tolerably common. They all dwell among trees and shrubs, and might far more appropriately be called tree-vaulters than grass hoppers. They are all of a green color, with very long, slender legs and antenna, and the females are all furnished with curved or saber shaped ovipositors, formed of two pairs of flat tened sheaths which inclose two narrower piedes. The base of the front tibiae or shanks is some what dilated, with an oval cavity each side, closed, by a memhranaceous covering. In the Oblong-winged species the first and middle shanks have such cavities, but in the other three species it is found only on the front shanks. Our most common species is the Angnlar-winged Katydid. The eggs of this species are more or less flattened, usually of a slate color, some times inclining to brown, and are deposited in two rows overlapping each other, and on the twigs of trees. The Narrow-winged Katydid is distinguished from the others by the length and narrowness of its wing-covers and by the male' having a cylindrical style curving from below upwards. The female has the ovipositor
much curved, and deposits her eggs in the leaves of trees. The Broad-winged Katydid has the wing-covers longer than the wings, and is distinguished from all otherd by the greater breadth and convexity of these wing-covers, which entirely enclose the abdomen. The eggs are deposited, says Dr. Riley, by means of the sharp ovipositors into crevices and soft sub stances, and probably in a state of nature, into the crevices of loose bark, or into the soft stems of woody plants. The Oblong-winged Katydid is not abundant in the West, and not found at all, we believe, in the latitude of and south of St. Louis. It is said to be at once distinguished by the perfectly oval form of the wing-covers, the long hind thighs, and by having the base of the middle, as well as of the front tibiae, swollen and furnished with a membranaceous cavity each side. The female has an ovipositor, interme diate in size, between those of the Broad and Narrow=winged species, or almost as long as the abdomen, and it is more strongly toothed for one-half its length than in any of the others. The notes of the male are described Harris as though grating, comparatively feeble.
