It remains <piietlv underground in its cell for about two weeks, and then changes into an ordinary beetle-chrvsalis. This is the last stage but oni-. and it extends to about twenty days ; then the bright little beetle emerges and proceeds to feed ajMrn the leaves of its food-plants and to tind a mate. Owing to its shining green colour it is not easy to see the beetle upon the leaves, but its presence is revealed b\ a peculiar r)dour it gives forth. The remarkable thing about thi-- series of changes is what has Ixen called the false-pupa stage. When it assumes tin form of a tlv's pupariuni, oni- would ex|ie( i that it would change into a ehrysali- within. A similar stage—as we shall see occurs only in a few other beetles, an-1 these all have somewhat similar habit . As the metamorphosis departs from tl"' usual course of the Insects which exhili t three distinct changes of form after tin KMoi-TFHi, t-gS-stage, it has been described as hypei- niip Of tho ant-lions, though ih.
