136 THE ENTOMOLOGIST. 



until I liave succeeded in breeding the gall-flies. The galls 

 were found in May, and were then, in the fresh state, 

 succulent, as yet exhibiting no ribs ; but in a few days 

 partly shallow, partly deeper, longitudinal furrows were 

 developed. They have now the same various appearances as 

 the Schenckian types. — G. L. Mayr. 



These galls are, I believe, common, and generally distri- 

 buted in Britain, but unnoticed. Dr. Traill has found them 

 in several localities in Scotland ; and I have met with them 

 in widely separated districts in Essex. Unless careful, we 

 here get into great confusion of nomenclature. Like our 

 common currant gall of the oak {S. haccarum) there are two 

 forms of this species — the leaf form, and the catkin form. 

 The description of the former has already been translated as 

 a distinct species {Aphilotftri.v 7narginnlis, Schlecht., Entom. 

 X. 298) ; and of the latter, from above, we see how many are 

 the varieties, which they certainly are, as is also doubtless 

 the species next described. Of these the two chosen names 

 of Schenck appear unfortunately to be A. pedunculi and 

 A. verrucosus. Pedunculi was applied by Linne to the 

 catkin form o{ S.baccarum ; and »S.t"^;T?<6'osrt of Schlechtendal, 

 a very distinct species, is described in the 'Entomologist' 

 (Entom. X. 249). It is, therefore, certainly not only con- 

 venient, but necessary, that these two names, applied to the 

 galls now under consideration, should be dropped, and that 

 this species should be known as Audricus quadrilineaius, 

 Hart., only. From these galls I liave bred Callimome 

 auraius., Fousc, a species of Pterou/alus ; and one specimen 

 of another unknown Chalcid. — E. A. Fitch. 



86. Andricus verrucosus, Schenck. — The typical gall, 

 from Von Heyden's collection, is brown, oviform, with a 

 longitudinal diameter of 5'2 millimetres, and a horizontal 

 one of 3'5 millimetres ; its surface exhibits wide, separate, 

 soft, rather indistinct, slightly raised, longitudinal striations 

 and irregularly placed warts; its apex bears a prominent 

 papilla; it occurs on the catkin stalk, and the remains of the 

 perianth and anthers may sometimes be recognised at the 

 base. Whether this gall belongs to a distinct species, or is 

 onh that of A. (juadrilhteaius or A. pedunculi, modified by 

 Sijueryi, is doubtful, for a Syneryus only was bred from it. — 

 G. L. Mayr. 



Doubtless a variety of the former species. 1 do not find 

 that Dr. Mayr has named the above-mentioned Syneryus, or 

 again referred to it. — E. A. Fitch.
