THE ENTOMOLOGIST. Q33 



[I guess, and it is little better than a guess, that the figure 

 is intended to represent Tryphajna fimbria. The broad black 

 border induces this opinion. — Edward Newman.] 



T. R. Archer Brings. — Gall on Hypochoeris 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, Werabury, South Devon, on 

 the flower-stems of Hypochoeris 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, not to be attributable to aninaal 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 I 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 hawkvveed (Hieracium) 

 and its allies, but only one — Aulax Sabaudi — has occurred 

 in Britain to my knowledge : this Cynips makes hair}^, 

 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. — E. A. Fitch.'] 



H. J. Channon. — Vitality in the Leg of a Buiierjly. — I 

 should like to ask if you could explain a curious phenomenon 

 I witnessed last May. My brother in setting out an Argynnis 

 Euphrosyne 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
