56 THE ENTOMOLOGIST. 



Q. LusiTANicA, Webb. (The Portuguese oak.) 



iV. lenticularis, 01. — Common on a good sized tree; in 1879 it was 

 rather less common ; and I have been told it was plentiful in the previous 

 autumn. I have also seen a specimen of this oak, gathered in 1864, with 

 several of these galls on. 



N.fiiviipennis, Hart. — Not rare in 1879, but I have not seen it this 

 season. 



S. baccarum, li. — I examined the tree very minutely several times in 

 1879 for this gall, thinking it might throw some light on the dimorphic 

 theory, which, if a reality, ouglit to have produced it, as N. lenticularis was 

 common in the previous autumn, and the tree is isolated ; my search proved 

 unsuccessful, but this season I was rewarded by finding two galls on one 

 branch, but could discover no more. 



D. divisa.^axL — Haifa dozen good specimens. 



Var. Q. TuRNERi, Willd. ; Q. lusitanica, var. Clusii, DC. (Turner's oak). 

 — Supposed to be a hybrid, raised by Mr. Spencer Turner in the Holloway 

 Down Nursery, Essex. A handsome evergreen oak, placed bj* DeCandolle 

 under lusitanica, though I think the old name should be retained in 

 preference to Clusii. 



N. mimismatis, 01. — Very abundant, literally swarming on the lower 

 leaves, though a small proportion only come to maturity; the rest I 

 imagine are affected by parasites ; they are smaller than on Q. Robur. 



C. Kollari, Hart. — Very common, both this and last season ; numbers 

 of the galls which, I believe, are affected by inquilines, do not get larger 

 than a pea, but, instead of the typical form, they are lengthened and have 

 an attenuated, or more correctly an acuminate point; intermediate forms 

 occur, or they would be taken for something else ; probably breeding will 

 throw light on this point. 



D. scutellaris, 01. — I have one gall which is undoubtedly this species ; 

 it is beautifully suffused with rose-colour, and has preserved the tint 

 in drying, though I fear it will ultimately vanish. 



Var. Q. iNFECTORiA, Oliv. — This is well known as the oak which 

 produces the galls of commerce. DeCandolle places it with lusitanica as a 

 subspecies, and, though the tree has a different appearance and is considerably 

 dwarfer, the fruits are almost identical. 



N. mimismatis, 01. — Over a dozen galls. 



N. lenticularis, 01. — Slightly commoner than last species. 



N. ostreus, Hart. — Three specimens. 



S. baccarum,, L. — Not rare on several trees. 



A. curvator. Hart. — Ten specimens. 



QuERCUS GLANDULiFERA, Bl. — This is an evergreen Japanese oak 

 extensively planted at Kew, where it forms dwarfish pyramidal bushes. It 

 exists in nurseries, and has been distributed under the name of Q. Austriaca 

 hybrida ; but as Austriaca is a synonym of Q. cerris, it is evident the 

 name is totally wrong. It was figured for the first time in ' Gardeners' 

 Chronicle' for December 4th, 1880, p. 715. It is interesting to note that 

 galls are found on it. 



S. baccarum, L. — Common on several trees both in 1879 and 1880, 

 though, as far as I could see, it was confined to the leaves. I bred the 

 maker, also that common parasite Callimome auratus from the galls.
