Dismorphia theucharila leuconoe

( Plate 9 , Fig. 33).

The egg is 1926.6 µm long and 592.8 µm wide; it is 3.25 times longer than it is wide and its width/length ratio is just less than 1/3; the maximum tube is at the level of the equator and remains constant until the fourth apical (Nh=4). The egg is sub-cylindrical elongated and acuminate in the upper pole; the base is convex and 3.3 times broader than the sharp apex and flat cusp. The apical area is very sharp from the sixth apical rib; toward the cusp, it presents a row of irregular polygons that immediately differentiate into axes and ribs of well-defined rectangular polygons. They have 51 to 56 ribs, often 54; they extend from the base until shortly before the end; generally, they are straight and coincide between axes, although they are also alternate; keep up intercostal spaces of constant amplitude, except in the basal area where they are significantly reduced; in the apical area, ribs are slightly curved and with greater intercostal space. There are 7 to 8 axes (LoA= 4 and ShA= 3 to 4); these are almost 3 times as thick as the ribs. The ShA are separated from the cusp by 1 to 4 ribs, frequently 3. The grid is rectangular; at the equator, the rectangles are almost 6 times longer than wide and slightly reduced at the ends. Conspicuous roughness against backlight and slight staining of the structures. The eggs show radial and bilateral symmetry. The following formulas are recognized:>4L3C (2LCLCLC, 2L2C2LC) and 4L4C (LCLCLCLC). Color N0 0A10M0 0.
