apex of the wing造句

• In the cilia, at the apex of the wing, is a small brown spot, and there are one or two others before it in the costal cilia.
• In " apicalis ", veins 7 and 8 are longer than their stalk, while vein 8 terminates in the costa just above the apex of the wing.
• The name is a combination of the rostrum and four elongated wings of nearly equal size, and uniquely a " R 1 " vein which almost reaches the apex of the wing.
• Forewing : costa increasingly to the apex, termen decreasingly to the tornus heavily edged with black; at the apex of the wing the black occupies about one-fourth of the wing.
• Beyond this a suffused white costal spot, where a fine angulated whitish line crosses the wing, followed by some brownish suffusion towards the apex of the wing, and scattered whitish scales.
• The branch R 4 is long and winding and reaches the costal margin, the branch R 5 terminates on the posterior border, so the second submarginal cell is open at the apex of the wing.
• The forewings are ashy-grey whitish with a slightly curved moderate black longitudinal streak above the middle, from the base of the costa to just above the apex of the wing, thickest on the basal third.
• The pale hinder fascia is very faintly indicated and the apex of the costa and hind margin are spotted with grey, and there is a darker grey ( almost black ) spot at the extreme apex of the wing.
• Beneath this an indistinct dark fuscous line runs from the apex of costal blotch to the dorsal blotch and there are some whitish-yellowish suffusion adjoining the white margin of the costal blotch towards the apex of the wing.
• There is a rather dark fuscous red-edged elongate pointed patch touching the preceding dark area in the middle of the disc and extending to the apex of the wing, its anterior portion broadly expanded to near the costa.
• The forewings are creamy white, a sharply defined narrow band of black raised scales slightly and evenly curved from the base along the median line to the apex of the wing, at the base this black band extends to the costa to one eighth.
• The conformation of the cells is strictly dependent on the morphology of the venation : the marginal cell is very narrow and opens as does the submarginal on the costal margin; the first rear cell is relatively long and opens close to the apex of the wing.
• R 4 terminates on the costal margin, R 5 terminates before the apex of the wing or, in some genera, at the apex ( but R 5 may also converge on the apex as in " Cyrtosarthe " and " Pseudatrichia " ).
• The wingspan of an insect refers to the wingspan of pinned specimens, and may refer to the distance between the centre of the thorax to the apex of the wing doubled or to the width between the apices with the wings set with the trailing wing edge perpendicular to the body.
• Fore wings always with a round, occasionally quadrate, black discocellular spot variable in size; in some specimens the costa is black only towards the apex of the wing, in others broadly black throughout and opposite the apex of cell so widened out as to touch the discocellular spot.
• There is also a roundish tornal blotch of dark fuscous suffusion extending over the termen to near the apex, as well as a series of short prismatic violet-blue-metallic dashes before the posterior part of the costa and termen, suffused together towards the apex of the wing.
• The forewings are light ochreous-yellowish, finely strigulated with deeper ochreous and with a slender slightly incurved deep yellow-ochreous streak, sometimes sprinkled with a few dark fuscous points, from the apex of the wing to two-thirds of the dorsum, continued along the dorsum to near the base.
• A fine fuscous line is found from five-sixths of the costa to the tornus, indented above the middle and there is an irregular transverse deep brown blotch sprinkled anteriorly with blackish and whitish occupying the area between this and the apex except the margins, with a black dot at the apex of the wing.
• There are some ill-defined small blackish dots towards the costa on the median third, and two or three somewhat larger before the apex of the wing, a subterminal series of several very undefined blackish dots on the costal half of the wing and a series of undefined blackish dots or marks along the termen.
• There is also a purplish-leaden angulated transverse streak beyond these, the lower portion thick and resting on the termen, the upper half margined posteriorly by an angulated brown streak sending a branch to the apex of the wing, and the angle connected with the tip of the preceding yellow costal mark by a brown mark.
