pointed aedeagus and a very slender clasper as compared to a more 

 abruptly pointed aedeagus and a stouter clasper in applana. The 

 female genitalia show fewer differences, but those examined indi- 

 cate that the ductus bursae of applana is longer in proportion to the 

 other structures than that of clemensella. I have examined 16 Euro- 

 pean and 41 American specimens, all of which bear out the above 

 conclusion. 



In view of this evidence, I believe it is certain that the European 

 applana does not occur in North America.
