Tetramorium colonies infestedwith Anergates contain only the workers of the host species. Adlerzand Wasmann have shown that these pay very little attention to thevirgin Anergates, but carry the males about and lick them assiduously,and that during these operations the latter assume a characteristic,motionless attitude. Both the male and female parasites are, of course,fed by their hosts, as they are quite unable to eat independently. 500 ANTS. Adlcrz and Wasmann have made some experimen
