2. TABANUS 421 



on leaves of Hazel (Coryhis). It is recorded from almost all Europe, or 

 at least from Central Europe and England to Italy and Greece, but the 

 Scandinavian record seems doubtful. 



Synonymy. — Walker said " Eyes bronzed ; facets of tbe fore part very small," 

 whicli would seem very inapplicable to this species, but I fancy he referred 

 to the lower facets when he said " facets of the fore part," because he used the 

 phrase " very small facets in front " under his T. at^'iccn^nis, and no species of Tabanus 

 has the facets of what I call the " fore part " or " front" small, so his statement 

 must surely mean that there is a contrast of facets somewhere ; there is also a 

 probability that Walker only knew the species from a female, because there is a 

 single female in the Entomological Club collection to which somebody has attached 

 (apparently more recently) a label of macvlicornis Zett., but which was probably 

 the specimen from which Walker drew up his description, though it was somewhat 

 absurd to describe the " Antenncehlack ; first joint testaceous ; second dark red ; third 

 " slender, dark red at the base."
