In a former paper A ) I endeavoured to show that E. pyrami- 

 data is only a variety in colour of E. marmorea. I was led to this 

 conclusion by finding one summer at Upsala two ? specimens, which, 

 as regards the colour of the abdomen, stood midway between E. 

 marmorea and E. pyramidata. This naturally led me to consider 

 whether there were any other characteristics in the form of the body 

 or in the colour, that might serve to distinguish these two so-called 

 species; but as the result was entirely negative, and I saw that E. 

 pyramidata differed from E. marmorea only in the different marking 

 of the abdomen, and I was now in possession of a series of speci- 

 mens, which clearly showed how the one form went over into the 

 other, I could not otherwise than decide that they belonged to one 

 and the same species. 



But the male of E. pyramidata was then unknown to me, and 

 I could not therefore be considered as having fully proved the iden-
