Several Insects of the following family are also sometimes found in it but this has been by destroying the natural inhabitants, of whose' domicil they have taken possession,. in the manner of the Ichneumons. Certain species are apterous. One species deposits its ova in t~e pollen of the eadiest of the wild Fig-trees. The mode.rn ?ree~s, m pursuance of a method transmitted to them from anuq~lty, p1erce several of these figs, and place them on t~eir late be~nng trees of the same genus; the Cynips soon leave their old dwelhng a~d come out loaded with the fecundating dust, insinuate themselves mto the eye of the fruit borne by the latter, fecundate its seeds, and accelerate the period of its maturity. This operation is termed caprifi· cation. IBALIA, Lat. Illig.-Sagaris, Panz.-Banchus, Fab. Where the abdomen is strongly compressed in all its height, and is formed like the blade of a knife; the antennre are filiform. The radial cell is long and narrow; the two branchials are very distinct, and completely or entirely closed, and the two first cubitals are very small(1 ). FIGITES, Lat. Jur. Where the abdomen is ovoid, thickened and rounded superiorly, or simply compressed and trenchant beneath; and where the antennre are granular and gradually enlarge. There is but one complete brachial cell, the radial is very distant from the extremity of the wing, and the second cubital is wanting(2). CYNIPS, Lin.-Diplolepis, Geoff. Or Cynips proper, where the abdomen is similar, but the antenn:e are filiform and not granular. There is also but one complete cell at the base of the superior wings; there are three cubitals, the first of which is proportionally larger than in the Ibalire; the radial is equally elongated.
