The American specimens differ from those of Europe, which also 

 vary, in having the red segments of the abdomen marked with a large 

 black basilar dorsal spot, the former having mostly only a darker cloud. 

 Panzer's figure, however, comes very near the American. 



[It is doubtful that the European species occurs in America ; they are 

 probably distinct]
