Abstract
II. CIEBOLD'S experiments extended over four years, and although v some hundreds of nests were more or less observed, only thirty—seven—but these amply sufficient—gave the answer to his questions, passing successfully through all the stages above noted. Firstly, they furnished a virgin colony in a nest absolutely free from eggs and larvae—except a few advanced larvae purposely left in some nests and noted down-which colony laid eggs; secondly, these eggs produced without exception (some few eggs not developing) males.
