In July last I noticed that the leaves of the burdocks on the Heights of Levis were riddled as if from a discharge of small shot. On examination, I found that the damage to the leaves was caused by numerous larvæ of a species of Cassida. The creatures were there in strength, each supporting, by means of the forked prolongation of its anal segment, its “stercoraceous parasol.” Towards the end of the month the grim-looking pupæ were to seen, bristling round their edges with white branched spines, and attached to the leaves by a natural cement. In the present month (August) the beetles have appeared. They are about eight millimetres in length and five millimetres in breadth.
