286 THE CANADIAN ENTOMOLOGIST 



Attention should be called to the fact that Stictiella exigua 

 Mickel. cf (Trans. Amer. Ent. Soc, XLII, p. 419) is the same as 

 divergens. However, Mr. Parker has assigned another male to 

 exigua in his monograph. Biological evidence is needed to show 

 which of these is really the male of exigua and to determine the 

 status of the name divergens.
