2. On a Collection of Lepidoptera made in Northern For- 

 mosa by H. E. Hobsonj Esq. By Arthur Gardiner 

 Butler, F.L.S., F.Z.S., &c. 



[Eeceived November 13, 1877.] 



Through the kindness of Dr. Lockhart, I have recently had the 

 pleasure of examining a collection of Lepidoptera sent home by Mr. 

 Hobson, who has generously permitted me to select, for the national 

 collection, those species which we required. 



In 1866 Messrs. Wallace & Moore published, in the ' Proceedings ' 

 of this Society, a list of the Lepidoptera taken by Mr. Swinhoe at 

 Takow: of the forty-six butterflies there enumerated seventeen only 

 have reappeared in the present series ; and some of these wdl not be 

 recognized as the same, owing to changes which have arisen in the 

 nomenclature of the Butterflies and in the views now held by msiny 

 lepidopterists of the localized character of the so-called variations of 

 certain species.
