The Prestpent exhibited the Diptera of W. J. Burchell’s 
British collection, and said that he was indebted to the kind- 
ness of Colonel J. W. Yerbury, Mr. G. H. Verrall, and Mr. 
J. E. Collin for the determinations. The chief interest of the 
collection lay in the large proportion of specimens taken in 
the garden of Churchfield House, Fulham; the great age of 
many examples, some dating back over 100 years ; the remark- 
ably full and precise data characteristic of this exact and 
keen observer ; and the light thrown upon the movements of 
the great naturalist, who, after his return from Brazil in 1830, 
became one of the most isolated and mysterious figures in the 
roll of British science. 
The Presipent also exhibited seven skins of African 
caterpillars preserved by W. J. Burchell during his travels. 
They were as follows :— 
(1) An unknown species of Papilio bearing the data 
*16.3.15. Pascitur in foliis Umbellifere dendrophylle aftinis. 
v. H.” Burchell was at “ Nieiw Kloof Station” on March 
16, 1815. “v. H.” means “vide Herbarium.” Burchell’s 
Herbarium is now at Kew. 
(2) The yellow and green form of Acherontia atropos, 
apparently full-fed. ‘22.12.14. Folia caulesque ‘ Solani 
tuberosi.’ editur Sphynx Atropos? 8. N.” The last two 
letters refer to the “Systema Nature.” The locality was 
“ Krombeks-river Station.” 
(3) Celerio lineata livornica, probably nearly full-fed. The 
skin was kindly compared by Dr. Karl Jordan with specimens 
of this species in the Tring Museum. No data accompany 
this preparation, 
(4) A green Cherocampid larva. ‘“ 28.11.14.” The species 
cannot at present be determined. The locality was “‘ Mountain 
Station.” 
(5) A brown Chwrocampid larva which Dr. Jordan thinks 
may be Vheretra cajus cajus, Cram. “7.12.14.” " This and (4) 
are on one piece of paper and from the same locality. Both 
are probably nearly mature. 
(6) An unknown Lasiocampid larva, ‘9.12.14. In mon-
