292 THE ENTOMOLOGIST. * 



Fagi), on account of its being inappropriate, as the larva 

 feeds on grass, like almost every other species of the family 

 Satyridae. It is surely not desirable to attempt to revive a 

 wholly inappropriate name, which might lawfully be changed 

 if its claim to priority were undoubted, especially as it has 

 never been current since its publication in the middle of the 

 last century. 



Satyrus Hyperanthus, Linn., and Lasioramala Clymene, 

 Esp. — In accordance with an admitted rule, the former 

 incorrect spelling of these names has been corrected by sub- 

 sequent authors, the names of the original authorities being 

 still attached to the species. There is therefore no reason 

 for reviving obvious and obsolete errors of this kind, espe- 

 cially as no object is to be gained by it. Some of these are 

 doubtless mere misprints. 



Genus Arge, H'ubn., Boisd. — This name is objected to by 

 Mr. Butler, on the ground of its being based on the mis- 

 chievous principle of changing a specific into a generic 

 name. Staudinger wisely adopts Meigen's name, Melana- 

 gvia, which he states to be three years prior to Boisduval's. 



The genera in Hubner's ' Verzeichniss der bekaunter 

 Schmetterlinge' are universally admitted, independently of 

 their excessive number, to be so badly defined as to be 

 worthless, when not fully characterized l:)y a subsequent 

 authority. Hence it is that Boisduval's genera are usually 

 received instead. Anlhocharis, for example, is preferred by 

 niost Entomologists to Euchloe. Guenee's name, Chorto- 

 bius, has, however, no claim to supersede Coenonympha, 

 Hilbn., Westw. Still less ought Guenee's name to be 

 attached indiscriminately to every family of Lepidoptera. 



The genus Cynthia, Fahr., was extremely heterogeneous ; 

 but the type-species, C. Arsinoe, Cram., as remarked by Mr, 

 ButLr, has no connexion with the genera Pyrameis, H'uhn.j 

 Doiibl., and V^anessa, Fahr. The two latter genera are, however, 

 much more closely allied than Cynthia is with either of them. 

 Whether the genus Grapta, Xf/i., should stand or not, 1 will 

 not attempt to decide. Genera being in many cases artificial, 

 it frequently becomes a mere matter of taste or convenience 

 whetiier ihey should be adopted or not. Their needless 

 multiplication is not desirable, though it would be well if 

 such large genera as Papilio or Pieris could be satisfactorily 

 subdivided.
