- n. A voracious biting fly, common in woods and bushes, and very troublesome to dogs. It somewhat resembles the black fly which infests cattle.
Sorry, no etymologies found.
The LXX. render this by a word which means the "dog-fly," the cynomuia.
The plague of flies (Heb. arob, rendered by the LXX. dog-fly), Ex. 8: 21-24.
"It is now generally supposed that the dog-fly is meant, which at certain seasons is described as a far worse plague than mosquitos.
This seems to identify the dog-fly of the Septuagint with the description of the Psalmist, Ps.lxxviii. 45, and to vindicate the conjecture that the tormenting mosquito, and not the house-fly, was commissioned by the Lord to humble the obstinacy of the Egyptian tyrant.]
