 Stephens. 



In most species of Lepidoptera the female is larger than the male 

 in alar expanse and the opposite condition in this species is noteworthy, 

 though found in several others. It does not hold for the other species 

 of the genus. In the oecophorid genus Scmioscopis it is the condition 

 found in all the species, that the males run considerably larger than 

 the females.

These two names ])ul)lished with short intervals stand for the same 

 species and mcrrickana must sink as a synonym.

Kearfott's name H . tiscana, published a few months after Hystc- 

 rosia baracana. falls as a synonym for it and witli it Meyrick's substi- 

 tute for Kearfott's name.

1907. Can. Ent., XXXIX, p. 123. 



This name has been placed wrongfully as a .synonym of H. 

 villana Busck. and should he resurrected as a valid species. The gen- 

 italia of this genus are remarkably uniform and difficult to dififerentiate, 

 but exhibit good characters, however small, in the form of the trans- 

 tilla and the armature of the penis.
