The eggs are remarkably large in this insect, about 60 in number, shaped like a 
hen’s egg, and reticulated, except at the small end, which is smooth, and bounded 
by a raised ring. When a specimen with fully developed ovaries is dried, the skin 
sinking in the intervals between the eggs, the abdomen becomes covered with small 
depressions, ¢ petits renfoncemens sphériques.’” (Haliday, MSS.)
