At n in the figure, a male scale and a female scale are shown natural size, theone on the right being the male. The male scale is thus much smaller, flatter, more elongate, and is of a whitish color. They often occur in considerable numbers among the large brown female scales in May and June. They are rare- ly seen after June, as they do not adhere strongl}' and thus soon '' weather off.'' The males doubtless emerge in May, but proba- bly live only long enough to mate with the then mature females. In their early stages, the male scales are scarcely distinguishable from the young females. The eggs.—This year, by the i8th of May many of the female scales had become full grown. And by tipping them over at this time, it was found that egg-laying had just begun. The female lays her eggs under her own body. During the process, her outer skin hardens and her body gradually shrivels thus making room underneath for the eggs. Egg- laying continues for a week or ten days, and, what was at the begin- ning a large fleshy soft-bodied female, becomes,when the task is finished, onl}^ a thin hard shell closely adhering to the branch and containing a mass of embryonic life in the form of minute white eggs. If one of these shells-be Fig. 3—c,eggs as lliev roll 07it from benealli a ,. , . _ . .,i , mother-shell in June ; enlarged. disturbed lU JUUC, it Will be found packed nearly full of eggs, which roll out when the shell is tippe
