the upper one — the larger of the two — is egg-shaped, and 

 surrounded by a thin whitish layer (of the inner gall) ; the 

 lower cavity — extending in a horizontal direction — is either 

 empty or filled with a spongy reticulation. — G. L. Mayr. 



Dr. Mayr gives no Synergus as inhabiting this gall, but 

 undoubtedly there is one, as in a letter from Mr. Rothera 

 relating to this gall, which he has found at Ollerton, near 

 Nottingham, he says : — " On making a longitudinal section 

 of a third gall, I found at the base the same irregular 

 decaying space as before; but in the neck of the gall three 

 chambers, separated by septa, and each containing a well- 

 developed maggot." This clearly points to Synergus. As 

 Dr. Mayr does not give the time of appearance of the gall, I 

 mav say Mr. Rothera found it first on the 27th of August, 

 and later immature specimens on the 28lh of September, but 

 in a different year; so the immature gall is probably to be 

 met with throughout the autumn. — E. A. Fitch. 



35. AiJliilolhrix Clementince, Gir, — This spherical gall 

 is about the size of a pea (five millimetres). Its base is 

 insignificantly elongate, and has at its 

 summit, exactly opposite, a short coni- 

 cal projection. It is of a brownish 

 yellow colour, and several small, flat- 

 tened, conical projections are irre- 

 gularly scattered over its surface, 

 Aphilothrix" Clementina, wliich is slightly rugose and sprinkled 

 a,&.GallsofA.Clementma^^^'/''h hairs, which are recurved in the 

 c. Section of the same. direction of the base of the gall. 

 Near the top, however, and especially 

 below the more or less distinctly-marked point, the growth of 

 these hairs is more abundant. The section exhibits two 

 layers of the consistency of leather: the exterior one is thin 

 and yellow; the interior also thin and red-brown, enclosing a 

 large spherical cavit}', in which the yellow spherical inner 

 gall lies loosely. Director Tschek informed me by letter 

 that he had found this gall lying on the ground under high 

 trees of Quercus sessiliflora, on the to]niiost branches of 

 which tree it appears to grow. The gall seems to fall late in 

 the autumn, generally after the first frost. Director Tschek 

 noticed in those galls which had recently fallen that they 

 still retained the bud-like scales at their base. Frauenfeld
