NOXIOUS FLIES OF PALESTINE.

Mosquito (Culex).  Camel Fly (Tabanus marocanus).

"He sent divers sorts of flies among them which devoured them."—Psa. xxviii. 45.

I may again mention here that the words "strain at" ought to have been printed "strain out," the substitution of the one for the other being only a typographical error. The allusion is made to a custom which is explained by reference to the preceding article on the fly. In order to avoid taking flies and other insects into the mouth while drinking, a piece of thin linen stuff was placed over the cup, so that if any insects, as was usually the case, had got into the liquid, they would be "strained out" by the linen.

Whether or not any particular species of insect was signified by the word "gnat" is very doubtful, and in all probability the word is only used to express the contrast between the smallest known insects and the largest known beasts. Gnats, especially those species which are popularly known by the word "mosquito," are very plentiful in many parts of Palestine, especially those which are near water, and are as annoying there as in other lands which they inhabit.

APTERA AND APANIPTERA.
THE LOUSE.

Insect parasites—The plague of Lice—Its effect on the magicians or priests—The Hebrew word Chinnim—Probability that it may be represented by "tick"—Habits of the ticks, their dwellings in dust, and their effects on man and beast.

We close the history of insects mentioned in Scripture with two parasites of a singularly disagreeable character.

With respect to the former of them, we find it mentioned in the account of the great plagues of Egypt. After the two plagues of the waters and the frogs, both of which were imitated by the magicians, i.e. the priests, a third was brought upon Egypt, which affected the magicians even more than the people, for a reason which we shall presently see:—

"And the Lord said unto Moses, Say unto Aaron, Stretch out thy rod, and smite the dust of the land, that it may become lice, throughout all the land of Egypt.
