Two Zonites, both visitors of the eryngo-heads during the heats of summer, are among the Meloidae of my part of the country. They are _Zonitis mutica_ and _Z. praeusta_. I have spoken of the first in another volume;[10] I have mentioned its pseudochrysalis found in the cells of two Osmiae, namely, the Three-pronged Osmia, which piles its cells in a dry bramble-stem, and the Three-horned Osmia and also Latreille's Osmia, both of which exploit the nests of the Chalicodoma of the Sheds. The second Zonitis is to-day adding its quota of evidence to a story which is still very incomplete. 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_[11] builds with partitions of resin in the shell of a dead Snail. This last Anthidium is the victim also of the Unarmed Zonitis. Thus we have two closely-related exploiters for the same victim. [Footnote 10: Cf. _Bramble-bees and Others_: chaps. i., iii. and x.--_Translator's Note_.] [Footnote 11: For the Cotton-bee, Leaf-cutter and Resin-bee mentioned, cf. _Bramble-bees and Others_: _passim_.--_Translator's Note_.] During the last fortnight of July, I witness the emergence of the Burnt Zonitis from the pseudochrysalis. The latter is cylindrical, slightly curved and rounded at both ends. It is closely wrapped in the cast skin of the secondary larva, a skin consisting of a diaphanous bag, without any outlet, with running along each side a white tracheal thread which connects the various stigmatic apertures. I easily recognize the seven abdominal stigmata; they are round and diminish slightly in width from front to back. I also detect the thoracic stigma. Lastly, I perceive the legs, which are quite small, with weak claws, incapable of supporting the creature. Of the mouth-parts I see plainly only the mandibles, which are short, weak and brown. In short, the secondary larva was soft, white, big-bellied, blind, with rudimentary legs. Similar results were furnished by the shed skin of the secondary larva of _Zonitis mutica_, consisting, like the other, of a bag without an opening, fitting closely over the pseudochrysalis.
