This is the largest and handsomest species of the genus found 

 in this country ; the variety a. of the male has not yet been cap- 

 tured in England, but it is not uncommon on the continent. The 

 highly coloured specimens appear to be the normal condition of 

 the species, which is very widely distributed over Europe, being 

 found in France, Italy, Germany, Switzerland, Albania, Denmark, 

 Sweden and Finland ; in most of these localities the coloured 

 specimens prevail, whilst in England they are rare. This insect 

 occurs at Erith, Darenth and Birchwood, Kent ; it is a summer 

 species, being found during July and August ; some very fine 

 specimens were captured by Mr. Samuel Stevens in Devonshire.
