15b. Cerceris echo atrata, new subspecies 



Figure 16 



Female. — This is the same in structm'e and color pattern as C. 

 echo echo Mickel except that the markings are light yellow and it 

 lacks the reddish amber on the propodeum and the first abdominal 

 segment so characteristic of the latter. 



Male. — Unknown. It may be confused with the male of C. 

 rufinoda rujlnoda Cresson, with which it is closely related. 



This is the eastern form of C. echo Mickel. From manuscript 

 labels by Banks found on some specimens, it is evident he had at 

 one time expected to describe this form as a new species under the 

 name of nigroris.
