 synonomy, as I thought I could deal better with it in another

"Dr. Staudinger fStett. Ent. Zeit, 1857, p. 252) seems at 

 one time to have incorporated C, immanata with russata, and 

 treated the forms of each as varieties of one species, i.e., the 

 truncata of Hufnagel. This name had been previously adopted 

 by Lederer in his " Versuch die europaishen Spanner," pub- 

 lished in 1853. Subsequently, however, we find that Dr. 

 Staudinger, in his " Catalog," places immanata, Haw., apart 

 from trnncata, and condenses into four forms of immanata 

 the eleven aberrations he had previously characterised as 

 forms of trnncata. The following table will, I think, show 

 this : —
