44 Observations on Cynipidae. 



is easily explained that an Andricus inflator gall is 

 often found super-imposed on one or more Aphilotrix 

 glohuli galls. I have only made observations on 

 Andricus inflator in the open air, and have not been 

 able to make any more exact attempts at breeding. 



[The twig gall is found in May on Qiiercus pedunculata and 

 Q. pubescens. 



Inquiline. Sapholytus connatus. 



Parasites. Mcgasttgmus dorsalis, Torymus auratus, Decatorna 

 Neesi, Pteromalus dissectus and P. Erichsoni. The gall often exhibits 

 buds upon it in the following year, and is perennial as regards its 

 growth. The fly has the mesonotum uniformly shagreened, twelfth 

 and thirteenth joints of antennae longer than broad, mesopleura 

 striated.]

Gall. These galls are easily overlooked from their 

 small size. They are formed upon a bud, and when 

 ripe are so deeply concealed within the bud-scales that 

 only the apex of the gall can be perceived. They are 

 conical, of a reddish brown colour when fresh, and 

 from the base of each there springs a slender appendage 

 which penetrates deeply into the axis of the bud. In 

 September or October the gall becomes loosened and 

 falls to the ground, and the appendage shrivels up and 

 falls off, but very often we find galls remaining in the 

 buds which on further examination prove to be adherent 

 to them ; hence the assertion that this gall passes 

 the winter in the bud. But it has been proved that 

 only inquilines or parasites are reared from those 

 adherent galls : we have an instance in this of what 

 is frequently found to be the case, that when an inquiline
