this way. Occasionally some galls are found which are clearly 
distinguishable in appearance from the rest. These are com- 
paratively small—one-tenth of an inch or less in diameter. ‘They 
distort the leaf more, are less waxy in appearance, and yellower 
in colour. When pressed they are firm and hard; when cut, 
woody and nut-like. These contain inquiline larve, two, three, 
or more in a single gall. The first imago of these (Synergus 
albipes) emerged on June 23rd. Other galls, normal in appear- 
ance, had been already attacked by parasites, the larve of which, 
as early as the end of May, were found actively feeding upon 
the juices of their hosts. By June 24th they had passed through 
their several metamorphoses and emerged from the galls. Mr. 
Fitch has been kind enough to determine the species, which com- 
prise Callimome auratus (male and female), two kinds of 
‘Pteromalide, and one Eurytoma ; all common in these and allied 
galls. As with other organisms, galls have their favourable and 
unfavourable years, and last season seems to have produced 
Spathegaster tricolor in exceptional numbers. In my own neigh- 
bourhood, where, as a rule, this gallis but sparsely met with, it has 
been this year found in comparative abundance both by Dr. 
Ransom and myself.—G. B. Rornzra; Nottingham, Noy. 18, 1878. 
A Beruytip (OxyurA) BRED FROM GALL OF ANDRICUS 
TERMINALIS.—-I have just received from Mr. G. B. Rothera a 
specimen of the common Perisemus triareolatus Férst (—Bethylus 
fulvicornis, Curt.) which emerged on April 14th last from an old 
oak-apple of A. terminalis collected in the previous December.—

Hepycurum BRED rrom Cynips Koniart GaLu.—Dr. Capron 
informs me that in May, 1877, he bred Hedychruwm (Homalus) 
auratum from these galls. I have never met with it as a gall- 
inhabitor, but Westwood says ““M. le Comte de Saint Fargeau 
states that the females of Hedychrum sometimes deposit their eggs 
in galls” (Introduction to Mod. Class. Insects, ii. 178) and both 
Kollar and Giraud obtained this species from bramble galls 
(Verh. z.-b. Gesell, Wien. xiii. 1288) where it was parasitic on 
Cemonus wnicolor. In the instance now mentioned, whether. the 
gall had previously been taken possession of by an Osmia, or 
whether the Ruby-tail was parasitic on some legitimate inhabitant, 
does not appear.—Ib.
