Hi Miss Cora B. Sanders on the Rhopalocera 



association of each record with a particular specimen. In 

 checking the data in the manuscript I have had much kind 

 and efficient help from Mr. J. C. Moulton, of Magdalen 

 College. The probability of error is so high in a work of 

 this kind, that the task of verification is both prolonged and 

 laborious. The manuscript of all papers on this Brazilian 

 collection requires the most careful comparison with the data 

 on the specimens themselves, with those contained in Bur- 

 chell's two manuscript note-books, and in Professor Westwood's 

 list, while the inevitable occasional inconsistencies between 

 these sources demand tlie utmost attention. 



Professor Westwood's manuscript Catalogue of " Burchell's 

 Morphides " contains both Morphinae and Brassolinse grouped 

 under 27 numbers, some of wliich were afterwards united by 

 a bracket. With one or two exceptions the material is 

 entirely unnamed. The list itself, which is neatly written in 

 a clerk's hand, contains several errors, of which the probable 

 corrections are indicated below. A note and two suggested 

 names in Professor Westwood's handwriting are seen oppo- 

 site three of the species separated out by him. A single 

 number in the list " M. 21 " refers to a Nymphaline butterfly 

 (a Prepona) accidentally included and afterwards detected by 

 Professor Westwood; while one Brassoline butterfly was 

 accidentally placed in the Catalogue of Hipparchia (H. 5) 

 and two of the same group in the Catalogue of Nyniphalines 

 (N. 18 and N. 20*). 



The following arrangement of numbers and dates is care- 

 fully explained in Awn. & Mag. Nat. Hist. ser. 7, vol. xiii,, 

 April 1904, pp. 309, 310. Notes, other than numbers and 

 dates, written on labels attached to the specimens are placed 

 between inverted commas immediately after the numbers in 

 heavy type, and immediately before the locality. They are 

 found on relatively few specij^iens. When a specimen bears 

 a number only, the date, recovered from Burchell's note-book, 

 is placed between square brackets. " a." and " p." associated 

 with the date stand for '' A.M." and " p.m."
