NORFOLK GALLS. 
(Communicated by the Rev. E. N. Bloomfield.) 
No list of galls or gall-makers has been published by our Society. 
It may be well, therefore, to give a list of a few galls or pseudo-galls 
met with by my friend Mr. E. Connold, of St. Leonard's, while 
staying at Aylsham in July, 1899. July is not a good month for 
galls, being too late for the early galls and too early for those of 
autumn. Galls of the following species were observed, most of 
which are of general distribution, but a few are decidedly worthy 
of note : — 
Cynipid®. 
Aulax glechom®. Green, or green with red hairy galls on the 
leaves of the Ground Ivy, Gleclioma hederacea. 
Aulax hypoch®ridis. Spindle-shaped swellings on the flower 
peduncles of the Long-rooted Cat’s-ear, Hypochceris 
radicata. Cromer. 
Aulax papaveris. Galls in the seed vessels of the Corn Poppies, 
Papaver rliceas and P. dubium, generally more or 
less distorting them. 
Diastrophus rubi. Spindle-shaped swellings on the stems of 
Brambles, Rubus fruticosus, &c. 
The following species all occur on the Oak : — 
Andricus inflator. Swells the ends of the twigs of Oak, which 
thus become thickened and shortened. In this 
the gall is concealed. 
Andricus curvator. Bladder-like swellings on the leaves, con- 
taining an inner gall. 
Andricus radicis. Polythalamous galls, often very large, at the 
root or on the trunk near the ground. 
Andricus Sieboldii. Gregarious galls on the small branches of 
young Oaks ; when young reddish and viscid, 
when old striated and woody. 
Teras terminalis. The well-known Oak Apple. Soft spongy 
swellings at the ends of the shoots.
