 INSECTS (continued) on poplars. Mr. Elliman knows of only one spot where the moth occurs in any abundance and that is Start- ups End reservoir, where a row of willows may be seen stripped every year by the larvae. Single specimens have occurred now and then at Wil- stone reservoir. This observer is of opinion that the sluggish habits of the perfect insect account for its being so restricted in its distribution. In the Haileybury School List the larvae are said to be common and Mr. Matthews finds them to be fairly so at Stevenage. At Cheshunt this is a scarce species Ocneria monacha, L.
