Note 115 — LETTERS TO MERRETT.

Swarms of Ants and Flies are no uncommon sight along the seashore at certain seasons of the year, and under the conditions which Browne describes. The Pagets ("Nat. Hist. of Great Yarmouth") mention that the fly, Actora æstuum, is common on the beach at high-water mark; but Mr. Verrall writes me that there are many others likely to be thus met with, such as Orygma luctuosa and Limosina zosteræ, widely divergent species. In his "Journal of a Tour" into Derbyshire, Dr. Edward Browne, in crossing the sands of the Wash, mentions his satisfaction at the absence of the swarms of flies "with which all the fenne countrys are extremely pestered."
