" This beautiful little si)ecies is far more slender and delicate than 

 dlffiais or allies, and its position would be between the group of 

 which dijfiiiis B. is typical and the other composed of such species 

 as thijsbe F., gracilis Grt. etc. It can be distinguished at a glance 

 from any other known American species." 



This is almost surely H. rubeas Hy. Edwards. I have examined 

 a specimen of the latter which agrees very well with the description 

 and figure. Mr. Edwards informs me that he has a specimen he 

 takes to be this species and it seems to differ in the abdominal macu- 

 lation. It seems to me that much I'eliance cannot be j^laced on this 

 character in this species. The description is from Strecker's original 

 characterization of the species.
