Burchell's South American Nymphalmae. Since the author's 

 departure to Borneo the work has been continued by Mr. E. G. 

 Joseph, Lincoln College, who finished his description of the 

 Heliconiinae before the end of the year. There was some 

 delay in publication, and the memoir did not appear until the 

 number of the Ann. Mag. Nat. Hist, for April, 1910 (p. 322). 

 One hundred and sixty Burchell specimens, belonging to this 

 sub-family, were found in the cabinets, and their investigation 

 has produced one of the most interesting of the memoirs upon 

 the collections of the great naturalist. 



12. Assistance in Working out the Material of the 

 Department. 



By the lamented death of Mr. Edward Saunders, F.R.S., 

 the Department has lost one of its kindest friends. The great 

 English Hymenopterist was bound by special ties to the 

 Museum, which possesses the large collections made by his 

 father and cousin. His prompt and most efficient help will be 

 sadly missed. 



Dr. G. B. Longstaff, in addition to the munificent endow- 

 ment mentioned on p. i, and the specimens referred to 

 towards the end of this Report, has given much time and 

 labour to the Department, not only in working out the collec- 

 tions he hasmade,but also in carefullycopying from the drawers 

 of the British Museum a list of 2,244 species and 442 genera 

 of Hespcridac. This list, with its indices prepared by Mr. R. 

 Shelford (see Section 8), is now bound, and forms a large 

 volume which is of the utmost value wherever this important 

 group of butterflies requires to be studied. 



Dr. Karl Jordan, on one of his visits to the Department, very 

 kindly looked through the collections of American and Oriental 

 Papilioninae, which had been arranged in accordance with 

 the two great monographs in the Novitates Zoologicae. A few 

 errors were thus detected and set right. On another visit he 

 similarly confirmed or corrected the determinations in the 

 Nymphaline group Charaxcs. Large numbers of moths and 

 of African Longicorn beetles, previously taken to Tring, were 

 returned in the course of 1909 with determinations by Dr. Jordan 

 or Mr. Warren.
