Tystiolaeth: Another and rarer insect which is about is the big convolvulus hawk moth. I hear of its occurrence recently at Sale, and yesterday the corpse of one in a toffee-box reached me by post. The sender gave neither his name nor any particulars of locality; would he kindly let me have them? This moth is exceedingly irregular in its appearance, and is undoubtedly an immigrant, so that all records are of interest. TC
