THE EGG AND OVIPOSITION. A pair of moths newly reared was placed in a vial July 24, and next morning the female was found to have deposited singly, doubly, and in masses of from 3 or 4 to 20, a total of 235 eggs. The following day 24 were laid: on the 27th, 37 were found, or 200 in all. After- wards the moth died, hav- ing laid no more. A few eggs were found upon dis- section, making the prob- able number usually depos- ited between 300 and 350. Most of the moths die in confinement within a week. The egg.—The egg is of suffi- ciently large size, about four one-huudredths of an inch in length, as to be readily discern- ible to the naked eye. It is of oval form and rather variable in contour, being usually more or less flattened upon the surface of deposit, and there is often a distinct nipple at one extremity. Its greatest width is about three-fifths its length. The color when first laid is light gray, and under a strong hand lens the surface appears to be rugose and strongly iridescent. Under a higher power the surface is found to be made up of depressed irregular areas, mostly hexagonal and penta- gonal in outline.
