APHILOTHRIX AUTUMNALIS. re) 
the gall also appear. These are deeper, and also 
broader in some specimens than in others. 
The base is almost always surrounded by bud scales. 
In some examples these are absent or indistinct. An 
oceasional example will be attached to the twig by a 
stout peduncle. Under a pocket lens a number of 
very small purple, glossy papillae are seen in a few 
specimens. The apex is generally surmounted with 
a distinct projection, mostly simple, sometimes 
recurved. 
The gall develops as early as April, but normally in 
May, from the buds of the previous year’s twigs. As 
soon as maturity is past the gall falls off. 
Of the many hundreds I have found of these galls 
the largest measures 12 mm. high and 18 mm. at 
greatest girth. 
Cameron apparently considers this the same as 
Aphilothrix quadrilineata, and all its characteristics 
certainly favour the idea. 
It appears to have been first recorded as British by 
E. A. Fitch, from Essex in 1874. 
It is common and widely distributed; more easily 
obtainable on stub-oaks and small bushes than on 
large trees. 
Adler says: “ Aphilothriv albopunctata produces the 
same gall as that from which it emerges.”
