sidered by Kieffer (1901: 620) a synonym of our present in- 
sect. Forster’s original description is obviously inconsistent 
and it is not enough, it seems to me, for the certain recogni- 
tion of synonomy from the publication alone. Forster’s mate- 
rial came from France (Aix-la-Chapelle) , Switzerland, and 
Sweden, but no one, as far as I can find, has recognized the 
insect in additional material. This, admittedly, seems evi- 
dence that Forster had some common insect which is now 
passing under another name, and Kielfer may have been cor- 
rect in considering it a synonym of taschenbergi ; but since 
sulcata (1869) would then have precedence over taschenbergi 
(1870), and since the status of the generic name Liodora is 
further dependent on this decision — which cannot be substan- 
tiated by authentic specimens — I prefer to withhold judgment 
on the point and have relegated Liodora sulcata to the list of 
excluded species at the end of the present paper. 
Ormerod (1877, The Ent. 10: 43) recorded this gall as oc- 
curring on Q. cerris and Q. cerris Lucombeana in England. 
Fitch, on the same page in the same publication, questioned 
the determination of the cynipid. Houard (1908, Zoocecid. 
Europe 1: 330, 341) accepts Ormerod’s original data, appar- 
ently overlooking the fact that Ormerod himself (1878, The 
Ent. 11 : 201-204) soon decided that the galls he had collected 
were those of Andricus circulans instead of taschenbergi. 
There is, then, no basis for Q. cerris or its varieties as host of 
our Cynips.
