Dismorphia amphione praxinoe ( Plate 8 , Fig. 19).

The egg is 1564.1 µm long and 534.7 µm wide; it is almost 3 times longer than wide and their width/length ratio is 1/3; the maximum diameter is at the end of the second third (Nh= 20). The egg is ellipsoidal and quite acuminate at the distal pole; the base is convex and smooth, 2.5 times wider than the sharp apex and rounded cusp. The apical area is quite sharp, just from where the longer ShA ends, toward the seventh rib. They have from 27 to 32 ribs, extend from the base to the cusp; most are straight and parallel, alternating between axes, although they are also diagonal in the last apical quarter; they keep up intercostal spaces with variable amplitude and in the apical and basal areas, they are reduced. In the apex, the ribs are somewhat curved, as in the first basal row. They show from 8 to 11 axes (LoA = 4 or 5 and ShA = 4 to 6) that slightly protrude from the chorionic relief; these are thicker than the ribs. The axes project from the base shortly before the first rib. The ShA separate from the cusp by 4 to 8 ribs, often 6. The grid is made up of rectangles and at the equator, they are almost 3 times longer than wide; these are reduced in amplitude and size at the base but at the beginning at the cusp, they are extended and then progressively reduced. Roughness visible with backlight. The eggs exhibit radial or bilateral symmetries; the arrangement of the axes is variable, and the following formulas are recognized:>5L5C (LCLCLCLCLC), 5L4C (2CLCLCLCLCL), 6L4C (2LC2LCLCLC), 5L6C (LCLCLCLCL2C), and 4L4C (LCLCLCLC).
