NOTES ON '' A REVISION OF THE GENUS dNEIS" ^CHIONO- 

 BAS); " BY HENRY J. ELWES, F. L. S., F. Z. S.. PRESI- 

 DENT OF THE ENTOMOLOGICAL SOCIETY 

 OF LONDON, AND JAMES EDWARDS,

BY WM. H. EDWARDS, COALBURGH, WEST VA. 



Mr. Elvves has again favoured us with one of his periodical Revisions 

 of Genera, the last of which, relating to Argynnis, was reviewed by me 

 in the Can. Ent., XXII., p. 81, 1890. 



It is stated that Mr. James Edwards is responsible for the matter of 

 what are called " clasps" of the male, meaning the claspers of other 

 authors ; and these parts of the whole body of abdommal appendages 

 are the only ones treated of, or relied on. He has also given a compara- 

 tive table at the end, based partly on the facies, and partly on the 

 claspers. A plate of these last is appended. On p. 458 is a statement 

 of " the types of clasp-form " found in the genus : " in Noma and Jiitta 

 there is an unusual amount of variation, but the differences are merely 

 those of degree, and are not, in the most extreme cases, sufficient to 

 obscure the relationship of the species." Of like types of the "clasp- 

 form " are : — j '^'v N- 



1. Chryxus, Bore, Taygete. 



2. Urda, U/ileri. 3. Foreign all. 2. 



4. Semidea, Jutta, Full a. 



5. Subhyalina (which, according to Elwes, is Aino, Boisd., and 

 Cra7nbis, Freyer), Brucei, Noma. 



It strikes me that it is rather odd, if claspers are tests of affinity or 

 separateness, that Chryxus and Bore should fall together; or Setnidea 

 zxi^ Jutta; ox ^no axid. Nor?ia ; in each case the two species named
