My district possesses five: A. Florentinum, LATR., A. diadema, LATR., A. manicatum, LATR., A. cingulatum, LATR., A. scapulare, LATR. None of them creates the refuge in which the cotton goods are manufactured. Like the Osmiae and the Leaf-cutters, they are homeless vagrants, adopting, each to her own taste, such shelter as the work of others affords.

The usual door being inaccessible, a side-window had been opened by means of the insect's jaws. The cocoons, torn, but still in position in the lower rooms, left no doubt as to this eccentric mode of exit. The same fact, moreover, was repeated, in several bramble-stumps, in the case of Osmia tridentata; it was likewise repeated in the case of Anthidium scapulare.

Well, apart from a few irregularities, due either to cocoons whose larva perished in my tubes before developing, or to those inexperienced workers, the males, the result was the same in the case of Anthidium scapulare. The insects divided themselves into two equal batches, one going to the right, the other to the left. Tripoxylon figulus left me undecided.

I have obtained the Burnt Zonitis, in the first place, from the cotton pouches of Anthidium scapulare, who, like the Three-toothed Osmia, makes her nests in the brambles; in the second place, from the wallets of Megachile sericans, made with little round disks of the leaves of the common acacia; in the third place, from the cells which Anthidium bellicosum builds with partitions of resin in the shell of a dead Snail.
