Dismorphia crisia interrupta

( Plate 8 , Fig. 23).

The egg is 1321.4 µm long and 522.4 µm wide; it is 2.54 times longer than wide and the width/length ratio is 2/5; the maximum diameter is in the upper half, above the equator (Nh= 26). The egg is ellipsoidal and acuminate distally; the base is convex-hemispherical and smooth, slightly more than twice as wide as the sharp apex and flat cusp. The apical area is acute but truncated and it thins from where the longer ShA start, between the third and fifth ribs. They have 29 to 36 ribs, often 31 or 34, and on average 32; they extend from just before the base to the cusp; generally, they are straight, parallel, and alternate between axes, although they also coincide. The intercostal spaces are of constant amplitude, except in the apical (expanded) and basal (reduced) areas. At the apex, the ribs are slightly curved. There are 9 to 12 axes (LoA= 5 to 7 and ShA= 4 to 7), which protrude slightly from the chorion walls; they are 2 times thicker than the ribs. The LoA are projected from the base after the first rib and are depressed compared to the ShA; the ShA are separated from the cusp by 1 to 5 ribs, often 3 or 4. The grid is made up of wide rectangles, at the equator, they are near to 4 times wider than long and are reduced in amplitude and size at the base. Conspicuous roughness, but not stained. The eggs are asymmetric or with radial or bilateral symmetries. The following formulas are recognized:>5L5C (LCLCLCLCLC), 5L4C (2LCLCLCLC), 4L6C (L2CL2CLCLC, L2CLCL2CLC), 4L7C (L2CLCL3CLC), 6L6C (LCLCLCLCLCLC), 7L5C (2LCLC2LCLCLC), and 7L4C (3LCLC2LCLC).
