Through the great kindness of Dr. Seitz, of Frankfort, 

 and Director Robert Erhardt, of Munich, I have been so 

 fortunate as to obtain the loan of the six volumes containing 

 the unpublished coloured figures of the Hesfjeridse de- 

 scribed by Plotz. The identification of such obscurely- 

 marked Lepidoptera from descriptions, however carefully 

 worked out, is of itself a more or less hopeless task. 

 Plotz's descriptions are for the most part crude and 

 insufficient, and it has been impossible heretofore to 

 identify most of his published species. Plotz was an 

 indefatigable worker, his twenty-seven volumes of coloured 

 figures of Rhopalocera must have taken him a lifetime. 

 The Hesperidss are the last six, and for the most part his 

 figures are excellent, and a comparison with examples in 

 the collection in the British Museum, the very extensive 

 collection in my own museum, and the published figures of 

 the many authors who have worked at the Family belonging
