[I guess, and it is little better than a guess, that the figure 
is intended to represent Tryphena fimbria. The broad black 
border induces this opinion.—LHdward Newman.] 
T. R. Archer Briggs.— Gall on Hypocheris radicata.—As 
a great deal has been said lately in the ‘ Entomologist’ 
respecting different sorts of galls, I think it worth while to 
enclose some specimens of one which I found on Thursday 
last (5th August) at Knighton, Wembury, South Devon, on 
the flower-stems of Hypocheeris radicata. It may be common 
as a British species, but cannot, I think, be so in the neigh- 
bourhood of Plymouth. I have seen what may have been the 
same on an allied plant, Hieracium umbellatum. 
[The galls on the flower-stems of this plant, sent by Mr. 
Briggs, are, I think, noé to be attributable to animal influence, 
but to vegetal, as on examination I could find no traces of 
insect-life within the galls. The stem is no doubt attacked by a 
fungus of which I know nothing, except that I have never met 
with it myself. Only last year | mistook one of these fungoid 
excrescences for an insect-gall, viz., the elongate orange gall, 
to be met with on various grasses during the summer, which 
is produced by Hypocrea (Epichloe) typhina. I opened 
several which contained a white maggot, probably a species of 
Chlorops, which I afterwards ascertained had nothing whatever 
to do with the formation of the gall. There are three or four 
gall-making insects connected with the hawkweed (Hieracium) 
and its allies, but only one—Aulax Sabaudi—has occurred 
in Britain to my knowledge: this Cynips makes hairy, 
reddish, many-chambered galls on the stems. There are two 
others, which ought to occur in Britain, both Diptera,— 
Trypeta reticulata makes galls on the flower-heads, and 
Cecidomyia sanguinea makes small red galls on the leaves of 
Hieracium sylvaticum.—L. A. Fitch.) 
H. J. Channon.— Vitality in the Leg of a Butterfly.—I 
should like to ask if you could explain a curious phenomenon 
I witnessed last May. My brother in setting out an Argynnis 
EKuphrosyne pulled off one of its legs, which shortly after- 
wards began to move, curling the tarsi round, doubling up 
close at the next joint, and after a time stretching straight 
out again. This took place about every minute, and continued 
from four o’clock till eleven, having been placed on damp 
cork to prevent its stiffening; and next morning the tarsi
