There is another kind of gall, of an irregular shape, formed on oak-leaves. The 

 gall-fly that inhabits it is one of the " Inquilini," and dwells in a cocoon during the 

 pupa state, and is infested by Callimome mutabilis and Platymesopus tibialis. — -

On the duration of Hymenoptera in the Larva state more than one season.— Since the 

 instance of some individuals of the Fossores remaining in the larva state one season, 

 at least, longer than others collected at the same time, that I observed a few years ago, 

 as recorded in the ' Entomological Magazine,' I have not met with any instance until 

 this season, when I have observed it among another tribe of the order, Ichneu- 

 monidae. In the latter part of the autumn of 1844, I gathered a dead stem of a plant 

 about eight or ten inches long, with a dense cottony mass surrounding it, about the 

 size of a large hazel-nut, I put it in a tin pocket-vasculum which I had with me, 

 when I got home I put it by without remembering what was in it. I had no occasion 

 for it again until July, 1845, when I opened it and saw what I had enclosed ; I be- 

 gan to examine the mass of cotton, I observed in the centre of it the remains of seve- 

 ral small cocoons about a line in length, and near about a dozen larvae which had not 

 begun to form any cocoon. I observed them from time to time ; for about a month 

 they remained in the same state (without any of them changing into pupae) until they 

 died, which I believe was hastened by opening the cotton and disturbing them, as I 

 have several times observed that the larvae of Hymenoptera generally die after their 

 abode has been opened, and they have been moved about afterwards. — James 

 Bladon.
