A, \\ C, I), &c. Eows of spots running down to and forming the elliptic ornaments. b. Lowest spot or mark in row B. C. The next succeeding spot or mark in the same row. d. Apparently a broken prolongation of the spot c in the same row B &c. (see the lettered diagram on the right hand), of dark spots of the usual character. Each row of spots runs down to and is connected with one of the elliptic ornaments, in exactly the same manner as each stripe in fig. 57 runs down to, and is connected with, one of the ball-and-socket ocelli. Looking to any one row, for instance, B, in fig. 59, the lowest mark (b) is thicker and considerably longer than the upper spots, and has its left extremity pointed and curved upwards.
