imprisonment or by abstracting the vegetal substance 

 which serves for its support. In our common marble, or 

 Devonshire, gall, produced by Cynips Kollari, both cases 

 occur, (1) the inquilines living gregariously round the inner 

 gall and so destroying the Cynips, or (2) the inquiline living 

 singly in a small cell in the parenchyma, generally near the 

 petiole or base of the gall : when this is the case the 

 Synergus and Cynips may be bred from the same gall. Which 

 particular species of Synergus this refers to I believe has not 

 been satisfactorily determined, but our knowledge of the 

 economy of the different insects inhabiting galls is very 

 unsatisfactory at present. — E. A. Fitch. 



24. Cynips caliciformis, Gir. — The 

 spherical, pea-sized gall of this species is 

 found in the axils of the leaves of Quercus 

 pubescens, rarely in those of Q. sessiliflora 

 or Q. pedunculata. Its brown (at first 

 green) surface is beautifully faceted and 

 closely covered with very short hairs, 

 somewhat in the form of scales. Each 

 facet is either convex or nearly flat, and 

 has in its centre a small shining, generally 

 hairless, papilla. The section shows this 

 layer of bark to be thin and united with 

 the large, moderately thick-walled inner 

 gall. The gall is not deciduous. I have 

 not yet been able to obtain the gall- 

 maker. — G. L. Mayr. 



This species is very rare on the Con- 

 tinent, and has not been found in Britain. Synergus 

 melanopus, S. Reinhardi, and Ceroptres arator, occur in its 

 gall.— £". A. Fitch.

Doings at Sallows. By G. F. Mathew, Esq., R.N., F.L.S. 



Writing to several of my entomological correspondents 

 lately, I have complained bitterly of the absence of sallows 

 within easy reach of Dartmouth, for the few bushes I then 

 knew of were either so tall or surrounded by such a mass of 

 brushwood as to be entirely inaccessible. I have since,
