There is a specimen of the female of this species in Mr. Kirby's 

 type collection without a name ; but in his own interleaved copy of 

 the ' Monographia ; it is named cornuta, which name I have adopted. 

 Both sexes were taken on Cove Common, near Blackwater, Hants, 

 and described as distinct species. Since that time the species has 

 been bred from the stem of the common dock ; the sexes are there- 

 fore united as constituting one species.
