 Schenck). — This gall is found, according to Schlechtendal, 

 on Q. pedunculata, and is distinguished from the former by 

 its margin being more or less raised, its smaller size, — only 

 reaching to a diameter of three millimetres, — and by its 

 markedly thinner appearance while still on the leaf: Von 

 Schlechtendal also writes me that this gall is always of a 

 more reddish hue, and that he has never met with a specimen 

 showing the yellow colour of N. lenticular is. It is scantily 

 covered with short radiating hair, of a rusty red, and after 

 falling it swells considerably at its under side. Schlechtendal 

 obtained the gall-flies, which differ considerably from the 

 former species, between the end of April and the middle of 

 May.— G. L. Mayr. 



This species is moderately common, and widely distributed 

 in Britain, though nowhere so abundant as Lenticularis. I 

 have collected many hundreds of the galls, but never yet 

 succeeded in breeding the makers; they are later than the 

 former species — hence probably ray failure, as it is difficult to 

 keep the spangles moist without moulding, during their 

 growing or swelling state, through the winter; this gall, like 

 the former, makes a home for Synergun Txclieki. Marshall, in 

 his descriptions of the British Cynipidce (E. M. M.iv.), seems
