In the Kirbyan collection is a specimen of this insect without 

 a name ; but in Mr. Kirby's interleaved copy of his Monograph 

 it is named cornuta, a name which I had given it before I saw 

 the MSS. notes. A specimen of each sex w^as taken on Cove 

 Common, Hants, but described as distinct species ; since that 

 time Mr. Douglas gave me some stems of the common Dock, 

 which were evidently perforated by an hymenopterous insect; 

 these produced both sexes from the same stem, and conse- 

 quently I retain the manuscript name given by Mr. Kirbv for 

 the female of the species.
