Appendix. 



The following species, attributed to this family, I. have not 

 thought it necessary to include at present. 



97. Acidalia oppilata, Walk. 776. The single specimen is in 

 such poor condition as to be unidentifiable, being one of the 

 obscure group of A. recessata. 



98. Acidalia despoliata, Walk. 778. I could not satisfy myself 

 that the type of this (which I formerly quoted as a synonym of 

 A. recessata,) was truly referable to any species known to me ; it 

 may perhaps be an unrecognised additional species. 



99. Acidalia schistacearia, Walk, 1609, is a species of Dichro- 

 modes, belonging to the Oenochromidae. 



100. Acidalia jjrimaria, Walk. 1610, is a synonym of Idiodes 

 apicata, Gn. ( Boarmiadae). 



101. Acidalia posticaria, Walk. Suppl. 1633, is probably not of 

 this family, but I have not been able to examine it critically. 



102. Idaea farinalis, Ros., Ann. Mag. N.H. 1885, 402. This 

 may or may not be an Acidalia; it does not seem to be sufficiently 

 described, and I have failed to identify it. 



103. Hypochroma nyssiata, Feld. pi. cxxv, 3, belongs to the 

 Bomhycina ( LijxirididaeJ.
