apex of vein造句

• Hindwing : uniform; a slender short filamentous tail at apex of vein 1, very often absent.
• Hindwing more produced posteriorly at apex of vein 3, where it forms an elongate tooth or short tail.
• Cilia of both forewings and hindwings and tail at apex of vein 2 of the hindwing as in the male.
• Female upperside, forewing : a beautiful lilacine blue with a white central patch that occupies the lower apical half of the cell and the basal three-fourths of interspaces 3, 4 and 5; apex of wing and upper portion of termen broadly black, the inner border of this colour curving from a preapical point on the costa to apex of vein 3, thence the black continued as a slender anticiliary line to the tornus.
• Hindwing : ground colour more uniform to apex of cell, beyond this interspaces 2, 3 and 4 with broad elongate white spots, the spot in interspace 2 slightly tinged outwardly with crimson; sometimes a white crimson-tinted spot also in interspace 1; a subterminal series of crimson lunules in interspaces 2 to 5, that in 5 generally more or less white; lastly, a crimson spot at apex of vein 3 and on apex of tail.
• Male upperside : somewhat more than half the forewing from base velvety black, apical half dull fuliginous; cell-area with or without two short transverse orange bars; a blue patch above, the tornus; the outer margin of the basal black area obliquely zigzag in a line from the middle of costa to apex of vein 2, including a large discal, generally obscure ocellus, which, however, in some specimens is prominently ringed with orange-yellow.
• Hindwing : crossed by nine white bands or lines as follows : three between base of wing and apex of cell, those posteriorly in interspace 1 or on vein 1 abruptly turn upwards and terminate on the dorsum; the first band beyond the cell extends from vein 6 to vein 2, then curves upwards in interspace 1; the next extends straight from just below the costa to vein 4, thus overlapping the previous band for a short distance; the next or postdiscal band runs between the costa and vein 3, the subterminal two also between the costa and vein 3 but the inner one of the two bands is extended down to interspace 1 and there curves upwards towards the dorsum; both the subterminal bands are more or less lunular; in the interspace below vein 2 is a large subterminal black spot speckled with metallic blue scales and bordered inwardly by ochraceous orange; there are also in interspaces la and 1 two black dots inwardly edged by a short white streak set in an ochraceous background; lastly, there is a complete terminal white line followed by a black anticiliary line and a filamentous short black white-tipped tail at apex of vein 2; cilia as on the upperside.
