Dismorphia crisia foedora

( Plate 8 , Fig. 22). The egg is 1217.5 µm long and 524.4 µm wide; it is 2.32 times longer than wide and the width/length ratio is 3/7; the maximum diameter is at the equator (Nh= 5). The egg is elongated citriform; the base is convex and smooth, 2.5 times wider than the obtuse apex and flat cusp. The apical area is slightly sharpened, toward the fourth apical rib. They have 28 to 34 ribs (mode = 31), which extend from the base to the cusp; they are mostly straight and parallel, although there are also diagonals and curves (apical area). The ribs coincide between axes and keep up intercostal spaces of constant amplitude, except the apex (they expand) and base (they are reduced). They show between 10 and 11 laminar axes (LoA= 5 and ShA= 5 or 6), which slightly protrude from the chorion walls; these are 1.5 times thicker than the ribs. The LoA are projected from before the first rib; the ShA are separated from the cusp by 3 to 4 ribs, often 3. The grid is made up of rectangles, at the equator they are 3 times longer than wide, and they are reduced in amplitude and size at the base and the apex. Conspicuous roughness, mainly with backlight, although it does not stain. The eggs show radial or bilateral symmetries; the arrangement of the axes is variable, and the following formulas are recognized: 5L5C (LCLCLCLCLC) the most frequent, and 5L6C (LCLCL2CLCLC) less frequent.
