The caterpillar feeds on the seeds of the apple, and the female deposits her eggs on their germ. P. vitis, Bose., Mem. de Ia Soc. d, Agric., II, iv, 6. Superior wings deep greenish, with three oblique, blackish bands, the last terminal. Its caterpillar is very injurious in vineyards. P. prasinaria, Fa b.; Rres., Insect., IV, x. The largest species known; superior surface of the upper wings light green, with two oblique white lines. On the Oak, &c. Its caterpillar is one of those that Reaumur compares to a fish. Its cocoon has the form of a batteau( 1 ). The seventh section of the Nocturna, that of the GEoMETRlEPhalamites, Lat.; P. geometre£, L.-comprises Lepidoptera in which the body is usually slender, the proboscis either nearly wanting, or generally but slightly elongated, and almost membranous. The inferior palpi are smalJ, and almost cylindrical. The wings are ample, extended, or tectiform and flattened. The antennre of several males are pectinated. The thorax is always smooth. The caterpillars usually have but ten feet; the others present two more, and those at the anus always exist. Their peculiar mode of progression has caused them to be styled .!Jrpenteuses, Geometr:.e, or ft'leasurers. When about to advance, they first cling with their anterior or squamous feet, then elevate their body so as to form a ring, in order to approximate the posterior extremity of the body to the anterior, or that which is fixed; they cling with the anal feet, disengage the first, and move the body forwards, when they recommence the same operation. Their attitude when at rest is singular. Fixed to a branch of some plant by the anal feet only, their body remains extended in a straight line in the air, and absolutely motionless. So closely does the skin resemble the branch in its colour and inequalities, that it Finally, others again in which the wings are narrow and elongated, and the inferior palpi longer and salient, species which closely resemble the Crambi of Fabricius, near which they must probably be placed, constitute a third subgenus, PauCIBA. u, of which the Pyruli8 aald<mana, Fab., is the type. For the other species, see Fabricius and Hubner. (1) Messrs Lepeletier and Serville, with the Pyralu Godarti, previously described by them, have formed the new genus M:.A.TU.ONULA., differing from others of this division in the following characters; the labial prupi shorter than the head, with rather indistinct and almost glabrous joints; anterior coxz strongly compressed, and at least as long as t}le thighs.
