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 AeSsfi 
has in its centre a small shining, generally say 
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- Gyyips carzcrronms 
maker.—G@. L. Mayr. (and in section). 
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.— LE. A. Fitch. 
Doings at Sallows. By G. F. Matuew, Esq., R.N., F.L.S. 
WritINnG 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,
