met with; but we were rather shy of meddling with them. They are generally attached to the undersides of leaves, especially of the young Tucumá palm, which are broad, and offer a good shelter. Some are little flat domes, with a single small opening; others have the cells all exposed. Some have only two or three cells, others a great number. These are all of a delicate papery substance; but some have large cylindrical nests, on high trees, of a material like thick cardboard. Then again there are nests in hollow trees, and others among their roots in the earth, while the solitary species make little holes in the paths, and pierce the mud-walls of the houses, till they appear as if riddled with shot. Many of these insects sting very painfully; and some are so fierce, that on their nests being approached, they will fly out and attack the unwary passer-by. The larger kinds of wasps have very long stings, and can so greatly extend their bodies that we were often stung when endeavouring to secure them for our collections.
I also suffered a little from another of our insect enemies: the celebrated chigoe at length paid us a visit. I found a tender pimple on the side of my foot, which Isidora pronounced to be a "bicho do pé," or chigoe; so preferring to extract it myself, I set to work with a needle, but not being used to the operation, could not get it out entire. I then rubbed a little snuff in the wound, and afterwards felt no more of it. The insect is a minute flea, which burrows into the skin of the toes, where it grows into a large bag of eggs as big as a pea, the insect being just distinguishable as a black speck on one side of it. When it first enters it causes a slight irritation, and if found may then be easily extracted; but when it grows large it is very painful, and if neglected may produce a serious wound. With care and attention, however, this dreaded insect is not so annoying as the mosquito or our own domestic flea.
Having made arrangements for another and a longer visit to Magoary, we packed up our hammocks, nets, and boxes, and went on board a canoe which trades regularly to the mills, hringing the rice and timber, and taking whatever is-required there. We left Pará about nine at night, when the tide served, and at five the next morning found the vessel lying at anchor, waiting for the flood. We were to proceed on to the mills in a montaria, or small Indian canoe, and as we were five with the Negroes who were to paddle, I felt rather nervous on
