III. EemarJcs on Mr. A. B. Wallace's '' Pieridse of the 

 Indian and Australian Eegions." By W. C. 

 Hewitson, F.L.S. 



[ Bead 6th January, 1868. ] 



I BEG to submit to the Society a few remarks on Mr. 

 Wallace's Catalogue of Eastern Pieridce, from the perusal 

 of which I had been expecting much pleasure and in- 

 struction. 



And first, as to genera. Mr. Wallace has adopted Thyca, 

 proposed by Wallengren, but rejected by Vollenhoven, 

 and has made two new genera of his own, TacJiyris and 

 Prioneris. I cannot think that a genus which like Thyca 

 or Tachyris, is established on one character only, unaided 

 by some general trait which at once points it out to the 

 eye, and especially where, as in Tachyris, that distinctive 

 character exists in one sex alone, will be any aid to the 

 study of the Pieridce. Although in these remarks I shall, 

 for convenience of reference, quote Thyca and Tachyris, 

 I do not think that I can adopt them as genera. 



Secondly, as to species. After luxuriating in the beau- 

 tiful new species which Mr. Wallace has given us in his 

 Hyparete group of Thyca, one is met by the resuscitated 

 ghosts of many that I had hoped were laid for ever. Out 

 of 172 names (I speak only of Pieris as it was), there are 

 fifty which I would place as synonyms. It seems incom- 

 prehensible to me that I, certainly not tainted with Dar- 

 winianism, should have to contest this point with a gen- 

 tleman who, according to theory, ought not to recognize 

 species at all. 



The following references are to the pages of Mr. 

 Wallace's paper, in Tr. Ent. Soc, 3rd series, vol iv. 



Pieris narses, Wallace (p. 333) . 



I cannot adopt this name ; for bad as Donovan's figitre 

 of perimale may be, it was certainly intended for this 

 species, and the name perimale must be retained. 



Pieris nama, Moore (p. 340) . 

 Pieris nad.ina, Lucas (p. 341). 



These are the same species, and Lucas's name has 

 priority.
