The larva of the Death's Head was not uncommon at Aldington and Badsey on potatoes; I had a standing offer of threepence each for any that the village children could bring me. These large caterpillars require very careful handling, and I fear the children were not gentle enough with them, as I only had one perfect specimen moth from all the larvae they brought. One of my hop-pickers captured and presented me with a very fine specimen of the Convolvulus Hawk-moth at Aldington; they were generally comparatively common that year (1901) and a collector took no less than seventeen in a few days in the public garden at Bournemouth. The Clouded Yellow butterfly, whose appearance is very capricious, occurred one summer in Worcestershire in considerable numbers; it is strong on the wing and could easily reach the Midlands in fine weather from the south of England, where it is more often seen. Those I saw were flying high over clover fields, apparently in a hurry to get further north-west. The Marbled White is a somewhat local butterfly; there was a spot along the Terrace on Cleeve Hill, near North Littleton and Cleeve Prior, where, at the proper time, this insect was plentiful, but I never saw it anywhere else in the neighbourhood. One of the entomological prizes of the New Forest is the Purple Emperor; it is impossible to do justice to the wonderful sheen of its powerful wings. It inhabits the tops of lofty oaks, but does not disdain to come down for a drink of water, sometimes from a muddy pool, or even to feast on dead vermin which the keepers have destroyed. The Comma, so called from the C-mark on the under side of the hind wings, is fairly plentiful in Worcestershire and Herefordshire in the hop-districts, for the hop is its food plant; but it is curious that, with the abundance of hops in Kent, Sussex, and Hants, it is quite a rare insect in the south of England. The ragged edge of its hind wings is probably an arrangement to baffle birds in pursuit, offering more difficulty to securing a sure hold than is afforded by the even margin of the hind wings of most butterflies.
