Such may those be denominated which line the holes excavated in the earth for the reception of their young, with an elegant coating or flowers or of leaves. Amongst the most interesting of these is Apis Papaveris, (Megachile, Lair., Anthophora, F.) a species whose manners have been admirably described by Reaumur. This little bee, as though fascinated with the colour most attractive to our eyes, invariably chooses for the hangings of her apartments the most brilliant scarlet, selecting for its material the petals of the wild poppy, which she dexterously cuts into the proper form. Her first process is to excavate in some pathway a burrow, cylindrical at the entrance, but swelled out below, to the depth of about three inches. Having polished the walls of this, little apartment, she next flies to a neighbouring field, cuts out oval portions of the flowers of poppies, seizes them between her legs, and returns with them to her cell; and though separated from the wrinkled petal of a half-expanded flower, she knows how to straighten their folds, and, if too large, to fit them for her purpose by cutting off the superfluous parts. Beginning at the bottom, she overlays the walls of her mansion with this brilliant tapestry, extending it also on the surface of the ground round the margin of the orifice. The bottom is rendered warm by three 01 four coats, and the sides have never less than two. The little upholsterer, having completed the hangings of her apartment, next fills it with pollen and honey to the height of about hall an inch; then, after committing an egg to it, she wraps over the poppy lining, so that even the roof may leave this material; and lastly, closes its mouth with a small hillock of earth. - Reaum. 6.139 to 148. The great depth of the cell, compared with the space which the single egg and the accompanying food deposited in it occupy, deserves particular notice. This is not more than half an inch at the bottom, the remaining two inches and a half being subsequently tilled with earth.
