Having placed a small stone so as to intercept one of the lines, the whole body attacked it, and then immediately retired.
Shortly afterwards another body came to the charge, and again having failed to make any impression, this line of march was entirely given up.

By going an inch round, the file might have avoided the stone, and this doubtless would have happened, if it had been originally there: but having been attacked, the lion-hearted little warriors scorned the idea of yielding.
Certain wasp-like insects, which construct in the corners of the verandahs clay cells for their larvae, are very numerous in the neighbourhood of Rio.

These cells they stuff full of half-dead spiders and caterpillars, which they seem wonderfully to know how to sting to that degree as to leave them paralysed but alive, until their eggs are hatched; and the larvae feed on the horrid mass of powerless, half-killed victims--a sight which has been described by an enthusiastic naturalist as curious and pleasing!

Lieutenant Hutton has described a sphex with similar habits in India, in the "Journal of the Asiatic Society" volume 1 page 555.) I was much interested one day by watching a deadly contest between a Pepsis and a large spider of the genus Lycosa.
