A similar mode of feeding, but under circumstances of much greater security, is indulged in by _Antennophorus_, another ant-guest, whose relations with its host are of a still closer description. _Antennophorus_ is a mite which, according to M. Janet, fixes itself on to the head, or the sides of the abdomen, of the ant which it affects, and clings there as long as it sees fit. This it is enabled to do owing to a special adaptation of the feet, which end in little horny cups (_cornicula_ is the word here) furnished with some substance of so adhesive a quality that it might well be called “stickphast,” if no Latin word were at hand. Not all the feet, however, are of this description, for the anterior ones are transformed into a pair of long waving antennæ, which contain olfactory organs of the greatest sensibility. With these their owner makes up for the want of eyes, and, smelling and feeling its way, walks, when it wishes to, along the bodies of its hosts, passing from one to another. Sometimes, either by accident or otherwise, it becomes detached, and is then helpless as far as locomotion is concerned, but by no means so in other respects. Its object, now, is to reaffix itself: nor is it long before it succeeds in doing so. As it “lies upon the soil in one of the galleries of the nest it raises and stretches forward its first pair of ambulatory feet, and, at the same time, explores the space around it with its long antenniform ones. These appendages are much more agitated when an ant passes close by. Should it pass near enough, the _Acarid_ (which has a finer sound than ‘mite’) glues itself on to its body by means of the cup of sticky material at the end of one of its ambulatory feet, which it holds up ready for this operation, and it can, in this way, soon climb up and fix itself in a good position on its host. The latter is surprised, and seeks to rid itself of its strange companion, but failing in this, it becomes resigned very quickly (as we do to increased taxation) as soon as the _Acarid_ has taken up one of its normal positions.”[13] It will carry two indeed, or even three, without complaining. An ant with one of these burdens fixed, like the income-tax, to the under side of its head, and two others, which may stand for a rise in tea and sugar, is a very common sight.
