gemmations, which soon give birth to the third larval form, the 1 Budding 
Pseudogyne’ {Pseud, bourgeonnantc). This is apterous, and, except in size, 
resembles the first larval form. This third form has the power of repro- 
ducing its like several times ; that is to say, there may be several generations 
of the third form, but always by gemmation. It was upon this form that 
the experiments of Bonnet, Kyber, and other old observers were made. 
Towards the autumn a fourth larval form appears, and this developes 
wings. This returns to the Quercus coccifera, which is the winter habitation 
of the species. M. Lichtenstein names it the 1 Pupiferous Pseudogyne ’ 
{Pseud, pupifere ), on account of the nature of its products of gemmation. 
The progeny of all the preceding stages was agamic; that of this fourth 
form consists of forms which develope into sexually perfect insects. They 
are of two different sizes, and the insects proceeding from them are also very 
different. All are apterous and quite mouthless. The smaller ones are 
males, the larger females, within which may be seen a large egg, filling the 
whole body of the insect. This is the only true female in the whole series ; 
and after fertilization she deposits the true egg, which in the following 
spring will give birth to the 1 founder ’ {fondateur), which formed our 
starting-point.
