Remarks. — I do not hesitate to accept the above synonymy after 

 carefully studying the types of all three species. It is not surpris- 

 ing that the three species should have been described because of the 

 apparent differences. When carefully compared these differences are 

 reduced to mere shades of coloration. The specimens of teri/tiella are 

 somewhat darker than the type of pallideUa., and this is no doubt 

 due to the fact that they are in better condition than the rubbed type 

 of the latter species. A long reared series of serrae shows all but one 

 or two decidedly darker than either of the two types above, but this 

 depth of color is purely environmental. There are no differences 

 in the genitalia of either the males or females. 



Under this name a long series of both reared and captured speci- 

 mens from British Columbia and California has previously been 

 placed. Although the genitalia of these specimens are similar to 

 pallidella they are amply different in other respects. They are de- 

 scribed on an earlier page of this paper as A. fusciterminella^ new 

 species.
