Blowflies. 204 THE INTEGUMENT A L SKELETON OF THE IMAGO. the wing apex; o represents the thoracic attachment of the remigium and the radiating lines represent the successive positions of the anterior margin of the wing, seen in per- spective. Starting from the point h on the curve, the wing plane is approximately vertical, the dorsal surfaces of the two wings turned towards each other, and the apex of the wing in front of the wing-root. In passing from h to a, the anterior borders of the two wings are nearer each other than the posterior borders, so that the insect is driven forwards by the backward movement of the FIG. 36.—A Curve showing the loci of a point at the tip of the wing during flight, seen from below the horizontal plane passing through the wing-roots. During the descent of the wing from a to b, the plane of the wing is at right angles to its movement, so that the insect is borne upwards, and at b the wings lie in the horizontal plane. From b to c the wing slopes so that its plane corresponds with the plane of movement, the front edge of the wing cutting the air. The movement of the wing in the plane ob od is due to the combined swing of the propterygium on the axis of the dens, and the extension of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lowne, Benjamin Thompson, 1839-.
