2. Chrysalis dolioloides. Equivalent to the Pupa coarctata Linn. peculiar to those Diptera that assume this state in the skin of the larva.
ii. Mumia. All inactive pupæ which are covered by a transparent skin, through which all the parts of the inclosed imago may be seen, subdivided also into two.
1. Mumia coarctata. Corresponding with the Pupa incompleta Linn., which includes the Coleoptera and most of the Hymenoptera.
2. Mumia pseudonympha, confined to the Pupa of Phryganea and some others. This might be named Pupa subincompleta.
iii. Nympha. Under this denomination are included all insects that undergo only a partial metamorphosis, and are active in their pupa state, corresponding with the Pupa semicompleta Linn. and also subsemicompleta MacLeay. See Anim. sans Vertebr. iii. 285—.
M. Latreille has started an ingenious idea on this subject with regard to these kinds of metamorphosis, which comprehends both larva and pupa under a distinct denomination: as thus—
- Demilarve and Deminymph, synonymous with the Semicomplete Metamorphosis.
- Larve and Nymph, answering to Incomplete Metamorphosis.
- Caterpillar and Chrysalis, answering to Obtected Metamorphosis.
- Vermilarve and Pupa, answering to Coarctate Metamorphosis. N. Dict. d'Hist. Nat. xvi. 272.
