1832—for publication.” Then follow the numbers of the speci- 
mens, “ 365, 386, [3]79, 368, 369, 345.’ The insects with these 
numbers are Cefoniadae, bearing the names employed in the 
French monograph. The handwriting of the names is unlike 
that on any other Burchell specimen, but resembles the inscrip- 
tion in the copy of the monograph presented by Gory to Hope. 
A special peculiarity, which the two have in common, is the 
use of a small initial letter to capital names. Finally, Burchell’s 
names are twice misspelt in the monograph, and the same 
rendering appears on the specimens. 
The whole story becomes clear. Hope sent a number of 
his own specimens, together with six borrowed from Burchell, 
to help on the work of his French colleagues. Owing to some 
error on the part of sender or receiver, all were accepted as 
Hope’s, and all were therefore looked for in Hope’s collection, 
But Hope had returned the six specimens to their owner, and 
they only found their way to Oxford in 1865 with the rest of 
Burchell’s insects. 
We may conclude with confidence that the types of Gory’s 
and Percheron’s Pachnoda carbonaria and P. leucomelana— 
lost for over seventy years—are now recovered, together with 
other specimens described and figured in their monograph. 
Allusion has been made above to mistakes in the data 
recorded on the specimens; but considering the great age and 
inevitable manipulation of the collection, it is surprising that 
there are so few. In the vast majority of cases it is certain 
that the data are correct; and, again and again, confirmation 
is yielded by some character of the specimen itself. As an 
illustration, No. “1269” in the Brazilian Notebook refers to 
a wasp, of which “2 or 3 nests enveloped in cotton were 
brought from Carmo and the insect found on opening to-day, 
dead, having been unable [to] expand in the cotton. .. .” 
Dec. 4, 1828, When the specimen bearing “1269” was 
recovered, it was found that a little cotton fibre was still 
entangled in its limbs, while the wings were not properly 
expanded. Again, No. “651” in. the African Catalogue, 
placed last, unnamed, among the Longicorn beetles, bears
