RHOPA LOCERA MALA YANA.

I inserted both the description and figure of this species on the authority of Mr* Butler, 

 who id 1869 described the species as from Peuang; and in 1871 figured it in another 

 publication, still giving the same habitat. Mr- Butler now writes : * — 11 Originally described 

 from Pen ang, and on that account included by Mr. Distant in his * Rhopalocera Malayana'; 

 this locality, however, was an error arising out of the fact that the typo was labelled thus — 

 'P.', which with Wallace's specimens stands for ■Penang/ but with specimens received from 

 the East India Company (as Mr, Moore pointed out some two or three years since on a ticket 

 which is attached to this very species) it stands for * Darjeeling, Pearson/ Had Mr. Distant 

 examined my type, which by his own admission he did not do, he would have avoided the 

 repetition of this error.'* 



This argument would logically imply two axioms, viz, (1) Mr. Butler's recorded localities 

 cannot be taken without an examination and verification of the labels attached to his " types"; 

 and (2) if " types" are not contained in this country, neither names nor localities should be 

 nsed ; a 11 reductio ad ahsitnhim" Although Mr, Butler now definitely records his species from 

 the somewhat vague locality " Near Assam/' I have thought it best to still let it appear in this 

 enumeration, as his "P." may yet prove to be Penang and not "Darjeeling, Pearson/'
