 generally found in pasture fields.

Another local species, but widely distributed in England, 

 and reaching at least the south of Scotland. It is recorded for 

 Newcastle-on-Tyne in the " Manual," but I know no particulars. 

 Mr. Sang took it at Wolsingham, Durham, on 19th August, 

 1874, and at High Force, Upper Teesdale, on 1st August, 1878. 

 Mr. Gardner never took it there, but swept it up not un- 

 commonly from long grass on the sea-banks near the mouth of 

 Hezleden Dene. Although two or three pairs were in, cop. 

 when so taken, Mr. Stainton insisted, nevertheless, that all the 

 darker ones were lisontella and all the paler ones were 

 btrdella. Mr. Bankes, however, now says that the frenula 

 prove that every dark one is a male, while every pale one is a 

 female, and that they are all certainly bisontella, with the 

 female of which, he adds, Mr. Stainton was obviously most 

 imperfectly acquainted, for in the "Manual," ii, 287, he gives 

 the antennte of bisontella (i.e. in both sexes) as "very slightly 

 thickened with scales nearly to the middle," whereas in the 

 female they are strongly thickened thus to about the middle. 

 Two specimens previously taken in the same spot, and identified 

 for Mr. Gardner as vacculella, are pronounced by Mr. Uankes 

 to be typical bisontella.

This is given in Stainton's "Manual" as occurring at 

 Darlington, but it is not named in Sang's diary. Meyrick says 

 it reaches Durham, but this statement was doubtless taken 

 fi'om the " Manual " record, as he told me he had no special list 

 from Durham. I give it here, then, as an insect recorded from
