hi addition to the twelve species of butterflies already referred to, there are a number 

 of others in the Dufresne collection belonging to species described by Godart as new, and 

 labelled in the same handwriting. From Latreille's " Avertissement " to the ninth 

 volume of the Eneyclopddie, we learn that Godart worked through the whole of 

 Dufresne's cabinet, and therefore, although there is no special allusion to these speci- 

 mens, it seems to me quite fair to regard them as true types. 



By the comparison of these original and interesting specimens with others in the 

 Natural History Collections at the British Museum, I have been enabled to clear up 

 many doubtful points in synonymy, etc., and the following paper is the result of my 

 investigations. In submitting it to the Royal Society of Edinburgh, I must express my 

 best thanks to Dr Traquair, Keeper of the Natural History Department of the Museum, 

 for his kindly encouragement and advice, and also my great indebtedness to Dr A. G. 

 Butler, Mr F. A. Heron, Mr 0. 0. Waterhouse, and Mr C. J. Gahan, who, by their 

 generous assistance, materially contributed to the success of my work in London.

 COmea very near to Standinger's bid fa.
