REVISION OF THE OECOPHORIDAE — CLARKE 155 



Remarks. — This species is very much like packardella but may be 

 distinguished from it by the broken discal bar, its more striate 

 appearance, and usually larger size. The genitalia of the two species 

 are strikingly similar, but they can be distinguished by the characters 

 given in the keys. 



The single male from British Columbia is worn but undoubtedly 

 belongs to this species. The distribution of the species indicates this 

 specimen might be mislabeled or only a stray although further col- 

 lecting may reveal that the species is well established in the far West.
