term in the Verzeichniss, for .■ii/riiKjaria and ^firmiana. 

 Unless these two are identical or congeneric, and from the 

 extent of my present knowledge I must assume neither to 

 be the case, the type of Hijurochroa became, in 182S,Jinmana, 

 Cramer, through the action of Stephens in taking si/rinnaria 

 as the type of Pericallia. Since Stephens' term is pre- 

 occupied by Hiibner, Verzeichniss, 182, for Pericallia 

 viatronula, I have labelled the material in the collection 

 Roemer Museum, Cyphosea symKjaria, L. sp. I can attain 

 to no knowledge that Cramer's species is the same as that 

 of Linne, which would justify Mr. Meyi'ick's use of Hygro- 

 chroa, while all the authorities which I am now able to con- 

 sult, consider syrimjaria as peculiar and sui yeneris. 



^^ Selenia, Meyrick, I. c, 118. I had previously shown 

 that FAitrapela, Hiibner, 1806 (1811), must be used for this 

 genus with the type lunaria. 



. " Ennomos, Meyrick, I. c, 114. This term is correctly 

 employed by Mr. Meyrick, since Euyonia, Hiibner, com- 

 monly used for the species, is preoccupied in the Verzeichniss, 

 36, 1818. Its use for a genus of Butterflies is sanctioned 

 by Mr. Scudder. The type of Emwmof! is alniaria, L. sp, 



" Diastiitin, Meyrick, /. c, 103. The type of this term is 

 artesiaria. The same term is subsequently used for aryyralis 

 in the Verzeichniss, but its use in the FyraUdm must of 

 course be abandoned. Mr. Meyrick, however, includes with 

 artesiaria the type of Cyrnatophora, Hiibner, 1806 (1811). 

 Conceding the correctness of Mr. Meyrick's grouping, then 

 this genus would have to be called Cyrnatophora with the 

 type roboraria. The species generally included under 

 Boarmia, Tr., appear to be divided between Diastictis and 

 Selidosema, by Mr. Meyrick. The American species formerly 

 classed under Boarmia have been separated by Dr. Packard 

 under Cyrnatophora, and the use of this term, at a later date, 

 in the Thyatiridm has been properly abandoned. Again here 

 the use of Cyrnatophora as part of a trinomial term in the 

 Sammhmy does not affect the question. Its type is roboraria, 

 but what American or European species agree with this type 

 it is not for the nomenclator to decide. All agreeing 

 with this type must be referred to Cyrnatophora. The 

 exceptional clauses in Mr. Meyrick's diagnosis of Diastictis
