of gratitude to this distinguished authority on the group, not 

 only tor the specific determinations, many of which are of 

 great difficulty, but also for kind help and advice on special 

 points which arose' in the course of the work. 



The arrangement of numbers and dates is explained in 

 detail in Ann. & Mag. Nat. Hist. ser. 7, vol. xiii. (April 

 1904), pp. 309, 310. A further explanatory statement is 

 quoted from ser. 8, vol. i. p. 34 : — "Notes, other than num- 

 bers 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." 

 " 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.' " 



The geographical data and notes as to the character of 

 certain localities are in many cases more complete and detailed 

 in the following paper than in any of the preceding. This is 

 a result of the study of the earlier manuscript volumes of 

 Burchell's Catalogue of Brazilian Plants, containing the 

 numbers 701-5336. Quotations from this source are distin- 

 guished by a terminal asterisk, thus *. About half of the 

 catalogue of Brazilian plants has thus been studied and the 

 data copied, viz. from April 2nd, 1825, when Burchell set 

 foot in Portugal on his way to Brazil, up to August 23rd, 

 1827, when he was near the Rio Pardo on the journey from 

 S. Paulo to Goyaz. These volumes, now in the library at 

 Kew, have been kindly lent to Professor Poulton, at first by 

 Sir William Thiselton Dyer, F.R.S., and later by Colonel D. 

 Prain, F.R.S. Professor Poulton hopes that the whole of 

 the data from this source will be transcribed at no distant 

 date and made available for future papers. 



Professor Westwood's labels, whenever they have been 

 found attached to the specimens, are quoted in full. The 

 words " a Westwood's label " of course always imply that he 

 was the writer. " Westwood's list," on the other hand, is the 

 list prepared under his direction, and, in the great majority of 

 groups, written by an assistant. The condition of this list, 

 as regards the subfamily now under consideration, is set foith 

 in the two following paragraphs. 



Buichell's species of the genus Heliconius, together with a 

 single. Eueides, were included by Westvvood in his list of 

 " Heliconidae," described as follows in Ann. & Mag. Nat. 

 Hist. ser. 7, vol. xiii., April 1904, p. 306:— "The first 

 section of the butterflies is written in Professor Westwood's 

 own handwriting, and deals with the Heliconiidas id the old
