and May r on the "Mitteleui-opaischen Eichengallen" (Vienna), in 

 which "woi'k figures of the galls are given. 



Dryophanta folii, L. — Seems to be local, but widely distributed 

 throughout Scotland. I found it not uncommon in Perthshire. 



D. longiventris. Hart. — I possess Scotch specimens of this insect, 

 but without note of the locality where they were taken. Galls 

 agreeing with the descriptions of those of this species are not 

 uncommon at St. German's Loch and Gadder Wilderness. 



D. divisa, Hart. — Abundant all over Scotland. Local stations 

 are : — Kenmuir Bank, Cadder Wilderness, St. German's Loch, 

 Langside Wood, etc. The galls appear in July, and the flies enter 

 the perfect state in August, and remain in the galls during the 

 autumn and winter. The ovaiies, as I have observed by dissec- 

 tion, do not become developed till the time of oviposition is at 

 hand. In order to see the proportion of galls infested by inquilines, 

 etc., I set aside thirty galls, and out of the lot only seven gall- 

 makers came out, tlie remainder being inhabited by inquilines 

 or Chalcididce. A variety of the gall is found ; it differs in being 

 entirely white, without the usual red, the skin not smooth, but 

 very rugged, and beset with tubercles, which are often brownish. 



Aphilothrix fecundatrix, Hart. — A common sj)ecies met with in 

 most localities, Kenmuir, Cadder, St. German's. The galls are 

 easily recognised from their resemblance to a miniature artichoke. 

 At Kenmuir I have found larvae living in leaf-buds which were 

 not perceptibly enlarged or aborted, nor could a vestige of the acorn 

 be observed. 



A. radicis, Fab. — This species does not seem to be common ; the 

 galls are tmxnd on the roots of oaks at Cadder and Kenmuir. I 

 have captured the flies in January. At Kenmuir Bank, I 

 discovered a gall with every cell, and they amounted to between 

 two and three hundred, occupied by a Synergus. 



A. ferruginea, Hart (solitaria, Forsc?). — This is a very rare 

 species, and has, as yet, been only reported from this locality, 

 where I took it for the first time at Cadder Wilderness, and 

 between Carmyle and Kenmuir. The spindle-shaped, wool- 

 covered galls stick out of the leaf buds. 



Cynips lignicola, Hart. — Although so recently introduced 

 into Scotland, this is now one of our commonest gall-insects, 

 and in all probability it will, in a short time, be abundant all 

 over Scotland. Cadder, Kenmuir, Langside, St. German's, are
