THE ENTOMOLOGIST. 255 



In a subsequent note (second half, p. 68) Dr. Mayr says : — 

 " The gall falls in October, while it is yet fresh and soft, and 

 passes the winter on the ground." I have found the galls of 

 this species in Essex (see Entom. vii. 24, and Ent. Mo. Mag. 

 xi. 110) in the autumn, and even as late as the middle of 

 December, still in the bud, where it is easily seen on account 

 of its green colour. I, however, failed to breed any of their 

 inmates, probably from the inner galls withering, as no doubt 

 this species, like the Neuroteri (leaf-spangles), requires to be 

 collected from the ground in the spring to be successful. 

 Dr. Mayr gives Synergus ruficornis, S. vulgaris, and Calli- 

 mome regius, Nees, as inhabiting its galls; Prof. Kaltenbach 

 gives Siphonura chalybea, Utzh. ; Ratzeburg himself gives 

 Eupelmus azureus, which, as he says, is probably hyper- 

 parasitic ; and Hartig gives Neuroterus (Amerislus) parasiticus 

 as parasitic in the gall of this species. Another year I hope 

 to see which of these we have in Britain. — E. A. Fitch.

 much similarity between the gall of this and the 

 last-described species. Like that, more than half 

 is covered with bud-scales : it is, when fresh, of a 

 green colour, and has beneath the scarf-skin a thin 

 fleshy reticulation, and at the summit a small round 

 wart. It differs from the gall of A. globuli in its 

 more oval or prolate forai ; in its being from three 

 and a half to five millimetres long, and having in Bitu:<i,ae- 

 a diagonal diameter of two and a half to three *'^«^«'*- 

 and a half millimetres ; in the surface of the inner gall 

 having no reticular rings, but blunt, longitudinal slriations, 

 which also show on the surface of the brown gall, 

 for in the process of drying the thin fleshy layer adheres 

 closely to the inner gall. According to Hartig this gall does 

 not burst forth from the bud till the beginning of October, 

 and falls to the ground in the middle of the same month. I 

 have only found it once, but have had several fresh specimens 

 sent to me by Herr Tschek, of Piesting. — G. L. Mayr. 



This gall, I believe, occurs in Britain ; but owing to the 

 great confusion existing about the various bud-galls, I think 

 the less said about this rather obscure species the better, at 

 present. — E. A. Fitch.
