Cynipitlen, pp. 84, 85, a,nd 110; Mayr, Die mitteleuropaischen 

 Eichen-g.illen, p. 50, No. 72, pi. vi, f. 72, I find commonly around 

 Grlasgow. The very small size of the gall renders it easy to be 

 overlooked. 



Aulax hieracii, Eouche. — This gall-insect is regarded by Dr. Mayr 

 (and I have no doubt correctly) as a variety of A. sahaudl, H. I 

 found the galls in great abundance at Baldernock on Hieracium 

 syJvaticum, close to the roots of the plant, half buried in the soil. 



Periclistus cnnince, Hartig, is a common inquiline in this country, 

 in the galls of Uliodltes eglanterice, but seems to have been hitherto 

 overlooked. The galls tenanted by the guest gall-fly are readily known 

 from those inhabited by the gall maker, by their being considerably 

 larger, more irregular in shape, of a whitish-green colour, rarely 

 relieved by any red, and more particularly by being polytha:amous. 



Ceroptres cerri, Mayr, Verb. z.-b. AVien, xxii, 725.— At Cadder 

 "Wilderness I have taken two examples of a Ceroptres, which agree 

 very well with the description of G. cerri, and also w4th a type of that 

 species which I received from its able describer. According to 

 Dr. Mayr, cerri is an inquiline in the galls of Cynips cerricola, 

 Drijoplianta macroptera, Andriciis circiiJans, A. muUiplicatus, A. 

 crispator, aiid Spathogastcr gland if ormis,wone of Avhich I have hitherto 

 found in Scotland. At p. 672 of the above-mentioned work, Mayr 

 states that of C. arntor he has bred 600 females and not one mab ; 

 while of C. cerri he has reared 98 females and only 4 males ; so that 

 in this genus we have mixed partheno-genesis as in the latter, and 

 simple partheno-genesis, as in the former species. 



Through a lapsus at p. 227 of vol. xi, I have written Sapliolytus 

 apicnlis instead of Synerqus apicalis, Hartig, Germ. Zeits., 201, 11. 



Pentacrita nigra, Thomson, Ofvers., 1861, 399, may be added to 

 our lists. I have taken it at Dairy in August. And also may be 

 added : — 



Torymus hibernans, Mayr, /. c. xxiv, p. Ill, I having bred this 

 Chalcid from the galls of Neuroterus lenticularis, collected in Cadder 

 Wilderness. 



Pimpla, sp. — Two years ago I opened a young juicy gall of 

 Nematus viminalis, and found inside of it a small parasitic larva, 

 scarcely more than a line in length, and which, from its small size, 

 I considered to be a Chalcid. Being desirous of watching its de- 

 velopment, I carefully closed the gall again, bound it together with a 

 thread, and placed it in an air-tight pottle ; but before doing so, I
