The markings, as usual, are subject to be obliterated ; the palest 

 examples have generally the two apical cells of the membrane partially 

 ocellated, and the base, at least, of the abdomen black. The form of 

 the hemelytra and the smaller size distinguish it from ocellaris. Very 

 abundant throughout the season in some places of the metropolitan 

 district, Epping Forest, Darenth Wood, &c. ; also in Buddon Wood, 

 Leicestershire.
