Note. — ^Well established in the Puget Sound region and no doubt 

 wider spread than the above records indicate. May not have escaped 

 at London, Ontario. 



Remarks. — There appears to be no doubt of the synonymy as given 

 above. Ahhough I have not seen drijadoxena^ Meyrick's description 

 tallies with costosa and the locality for the former species agrees with 

 that of hlackmori. The food plant of dryadoxena {Quercus) is ques- 

 tionable, since the species of this genus rarely feed on such widely 

 separated species of plants and are more frequently host specific as 

 has already been pointed out. 



The genitalia of the males and females are identical except for 

 slight variation in the male harpes, a condition frequently encountered. 

 Pierce ^^ figures the genitalia of costosa showing the ostium opening 

 near the anterior margin of the genital plate. In the specimens I have 

 seen (4), both European and North American, the ostium opens 

 slightly nearer to the posterior than to the anterior edge (see fig. 273). 

 Furthermore, the signum as figured by Pierce lacks the anterior and 

 posterior points, present in all specimens I have examined. The sig- 

 num, it must be admitted, may be somewhat variable, but in this 

 species it appears to be unusually constant.
