 is an apterous female, in the small are apterous males. Would you not call 

 it a perfect analogy with the pi,stil and stamens which the flower contains? 

 We have here, I think, the only example in entomology of a winged form 

 being only transitory, serving only as a vehicle for the perfect sexual form, 

 a real flying cocoon, if I may express myself so. The little apterous aphids 

 which issue from these envelops have no rostrum, but are furnished with 

 generative organs and couple as soon as born. The male dies soon after ! 

 the female lays a sole egcj in the cracks of the bark or on the folds of the 

 leaves. This is the only and the real egg, quite different from the bud-egg 

 parthenogenetically laid, still more different from the egg of the winged 

 insect which I consider a real pupa or chrysalis, for that is, I think, the 

 only name meet for the envelop whence issues a perfect insect which couples 

 immediately." "It is peculiar to " Rhizaphis " vastatrix that the production 

 of winged individuals does not exhaust the subterranean colony ; it is viva- 

 cious and, like bees and ants, is parthenogenetically reproduced for four 

 years at least and probably even as long as tlie nourishment lasts." Notes 

 on the habits of several species.
