Epyris subeyaneus. Haliday, Ent. Mag. vol. v. p. 519. 
Specimens of this species were taken by W. W. Saunders, Esq., to whom I am indebted for a specimen. 
Mr. Haliday also kindly sent me a pair (but I am not acquainted with their locality). The Comte de Castelnau 
took it near Paris, and I have received it from the neighbourhood of Berlin, taken by Dr. Burmeister, from 
Stuttgart, taken by Van Roser, and near Brussels, from M. Wesmael, the latter under the name of Omalus 
fuscicornis Jurine, but that insect, as appears clearly from the figure of the fore wings, belongs to the flat- 
headed Genus Bethylus. 
The species was first described by Mr. Haliday, who mistook it for my F#. niger, which name he corrected 
subsequently to L. subcyaneus. I am obliged to alter the latter name from the fact that it is incorrect, the 
specimen described by Haliday having been washed over with gum water mixed with corrosive sublimate, which 
gave it an unnatural bloom. I have therefore applied to it the name of its lamented and most talented 
deseriber.
