REVISION OF THE OECOPPIORIDAE — CLARKE 101 



I have before me long bred series from various localities, all show- 

 ing some variation. Specimens from Sacramento, Calif., match Wal- 

 singham's description of argillacea^ while other bred specimens from 

 Washington State match the types of hlacella. The pattern of both is 

 identical. The depth of color and the definition of the discal spots 

 vary throughout the series. These characters cannot be used for dif- 

 ferentiation of species since, in any long bred series, all degrees of 

 depth of color or definition of spots may be found.
