Variety rosarum Fabr. In the European specimens the male 
is black with the basal corners of only the third abdominal 
segment reddish yellow, the fourth segment being entirely 
black. In the female the fourth as well as the third seg¬ 
ment have reddish yellow or metallic like spots, but no 
markings on the second segment. One female of this 
variety taken in Dane County. 
Variety duplicata n. var. In this variety the male has distinct 
spots on the basal corners of the fourth segment as well as 
the third segment. In the female there is not so much 
diffrence, there being in addition only an indistinct U- 
shaped marking on the second segment. I also have one 
female from Vilas County which lacks the markings on 
segment four.
