Dismorphia medora reducta

( Plate 9 , Fig. 28).

The egg is 1219.8 µm long and 477.1 µm wide; it is 2.57 times longer than it is wide and its width/length ratio is 2/5; the maximum diameter is at the equator (Nh= 14). The ellipsoidal egg is acuminate at the upper pole; the base is convex (sometimes flat), 2.5 times longer than the base, somewhat obtuse and flat. The apical area is slightly sharpened just where the most prolonged ShA begin, toward the sixth rib. They have 38 to 46 ribs (modes = 38, 42); the straight lines predominate, and these extend from the base to the cusp. They coincide between axes and keep up intercostal spaces of constant amplitude, except in the apical (are a little expanded) and basal (are conspicuously reduced). In the apex, the ribs are a bit curved. There are between 10 and 11 axes (LoA= 5 to 6 and ShA= 4 to 6), which are 2.5 to 3 times thicker than the ribs; the LoA are projected from the smooth base, before the first rib. The ShA are separated by 1 to 6 ribs from the cusp, often 4 or 5. The grid is rectangular; at the equator, the rectangles are almost 5 times wider than they are long, but they are reduced in their amplitude and size at the base; the intercostal spaces are concaved. Roughness almost imperceptible except with certain incident light; the staining is uniform in the intercostal spaces. Asymmetric eggs or show bilateral symmetry. The axes disposition is variable, and there are the following formulas:>5L5C (2LCL2CLCLC, LCLCLCLCLC), 6L4C (2LCLC2LCLC, 2LC2LCLCLC), 6L5C (2LCLCLCLCLC), and 5L6C (L2CLCLCLCLC). Color N0 0 A10M0 0.
