This species appears to be restricted to the north of England and 

 to Scotland. J discovered it in 1842, at Woolley Edge in Yorkshire, 

 about four miles from Wakefield ; since that time it has been received 

 from Scotland ; the specimens were identified by Dr. JNylander. The 

 species is found in Sweden, Finland, and Lapland. Dr. Nylander 

 suggests that Kirby's H. fulvicornis may prove to be the male ; but 

 that insect is the male of H. laevigatas. 



Div. II. The body more or less metallic.
