' | A HE following notes are supplemental-}' to my notes in this 

 magazine on Scottish Galls, giving the names of the 

 gall-makers in a few cases, and adding new localities for others. 

 Those on Brassica oleracea (Kail), are formed by Ceuthorhyn- 

 chus sulcicolhs Gyll. I have lately found them in great abun- 

 dance near Aberdeen. 



Quercus robur L. — (a) is the gall of Cy flips divisa H. : it 

 is generally distributed wherever there is oak; (b) is the 

 gall of Cy ?iips gemma L. ( C. fecundatrix, K.J ; (c) of An- 

 dricus curvator H. In describing this gall, I omitted to 

 mention that it contains a small inner gall, which is about 

 the size of a whinseed, brown, and very thin, and attached to 

 the inside of the larger gall. Inside of this inner gall the 

 larva lives. I have found the gall in April among fallen 

 leaves some miles north of Aberdeen, (d) Of this gall 

 also I took specimens this spring with the last, (e) I have 

 found in several localities near Aberdeen on fallen leaves 

 with the last, (f) Of the marble galls from Kinnoull the 

 majority prove to be the noted Devonshire galls,'"" formed by 

 Cynips lignicola IT. (C. Kollari Gir.j. They are spherical, 

 about y± of an inch in diameter, smooth, or with a few small 

 projections, and brown, usually with a tinge of green, in colour. 

 They are monothalamous, the central cavity being very 

 small in proportion to their size, (g) One of the galls, 

 however, is of a different species from the above, being 

 smaller, green, and polythalamous. (h) Among those 



* At the April meeting of the Perthshire Society of Natural Science, Colonel 

 Drummond Hay and Messrs. Herd and M'Farlane mentioned that they had 

 observed specimens of this gall (for three or more years) at Seggieden, Moncreiffe 

 Hill, and Methven Bog- — Editor.
