P\)r instance, immense fleas, which are THE IOLEX IRRITAXS. 385 sometimes twice or three times larger than usual, are found uponthe shores frequented by bathers, but they are of the same kindas that which attacks the human race. Fleas lay their eggs incracks, in cushions, and in boards, or in the midst of dust, andtheir larvae, which have no legs, and which, therefore, must livewhere they have been born, can only exist in consequence ofthe nourishment brought to them by the adults. Were theyabandoned they would perish, but they have excellent motherswho never leave them ; for after a flea, should it be a mother,has gorged itself with blood it seeks its young and disgorges asmall quantity so as to keep them THE METAMORPHOSES OF THE COMMON FLEA. {Putcx irriliUts.] The larvae shut themselves up in silken cocoons when theyhave attained their full size, and undergo their metamorphosisinto the condition of nymphs. In the engraving the long, legless,vermiform larva may be seen close to an inactive nymph, whichresembles somewhat the perfect insect, which has long legs andthe peculiar hairiness of the segments. The dogs flea {Piilcxcants) is smaller than the species which attacks man, and isdistinct from it, nevertheless it sometimes interferes with humanbeings. The Jigger, or Pnlcx penetrans, which lives in the hotdistricts of America, introduces itself under the skin of men andanimals, and grows there to a surprising size ; it is very smallwhen it is born. The male always retains its tiny size, and doesnot shut itself up for life ; but the
