red somewhat abated, though even after the Ply came forth, much ofthe original colour remained.

The manner in which it burfts open the cafe is rather singular;it does not force an opening in an irregular form, as mold Insectswhich spi n a case, but describes an exact circle within at one end;after this it divides its cafe according to that circle, only leaving asmall portion to act as an hinge; when it has extricated itself from theChrysalis, it forces the top of the cafe back, as shown in our Figure,and thereby a free passage is opened for its delivery.

The inside of the cafe is perfectly smooth, and appears as if po-lished by art; it is of a pale blue colour, the Chrysalis within is brown.

The Fly came forth on the 12 th of July, 1794.
