Dismorphia amphione isolda 

( Plate 7 View Figure , Fig. 17).

The egg is 1568.6 µm long and 574.6 µm wide; it is 2.74 times longer than wide and their width/length ratio is 3/8; the maximum diameter is at the equator (Nh= 6). The egg is ellipsoidal and somewhat acuminate at its distal end; the base is convex, slightly flat, and little more than 3 times as wide as the sharp apex and flat cusp. The apical area is quite sharp, just from where the longer ShA end, toward the eighth distal rib. They have 30 to 36 straight, curved, and diagonal ribs; these extend shortly after the smooth base to the cusp; they are alternate or coincide between axes and keep up intercostal spaces of constant amplitude, excepting at the apex where they are wider than at the equator. They display 9 or 10 axes (LoA and ShA = 4 or 5); these are 2 to 2.5 times thicker than the ribs (except in the apical area, where both keep almost the same thickness) and thin out a bit at the basal area. The LoA are alternately protruding with depressed ShA, generating concavities, which gives an appearance like the "star fruit" ( Averrhoa carambolo  ). The ShA are separated from the cusp by 3 to 8 ribs, often 6 or 7. The grid is made of rectangles that are almost 4 times longer than wide at the equator and reduce their amplitude and size at the base and at the apex. Very noticeable roughness with backlighting, slight staining in the center of the macro-reticulated cell; it could be a protomicrogrid. The eggs show radial or bilateral symmetries; the arrangement of the axes is variable, and the following formulas are found:>5L5C (LCLCLCLCLC), 4L5C (L2CLCLCLC), and 5L4C (2LCLCLCLC).
