provided. It is hoped that the appearance of the volume, 
with the full Brazilian Itinerary, stated by Burchell to be 
intended for the Botanical no less than for the Zoological 
Collections, will confer some benefits upon students in the 
great botanical centre of the empire. 
It is in like manner a great pleasure to reflect that the 
appearance of this work will benefit the British Museum of 
Natural History, whose staff has so greatly aided in its pro- 
duction. Burchell gave large numbers of his African dupli- 
cates, indicated by an L. in his catalogue, to Dr. Leach for 
the British Museum. A large proportion of these can be 
found in the collection ; several have become the types of new 
species, several have never since been obtained. Yet the data 
are wholly wanting. By the publication of Burchell’s catalogue, 
the fullest data of time and space and circumstance will be 
available for many of these, and something can be learnt 
about all of them. Furthermore, the whole study of insects 
will benefit from the recognition of the types of species de- 
scribed by Burchell himself, and by other naturalists, from the 
specimens in his collection. An example of the recovery of 
lost types suggests the kind of work which has been done, 
and indicates its usefulness. 
Gory and Percheron brought out their great monograph on 
the Cetoniadae (“ Rose-chafers” or “ Rose-beetles”) at Paris in 
1833. Many species described in it are spoken of as “ from 
the cabinet of Mr. Hope.” Nearly all these are well-known 
types in the University Collections. There remained, however, 
a few species—two of them types—which have never been 
traced, and specialists in the group have vainly searched our 
collections for them. All but one bear names proposed in 
manuscript by Burchell, but attributed by Gory and Percheron 
to Hope. The French coleopterists state of the single excep- 
tion that their own name had been printed before they received 
Mr. Hope’s suggestion. A sentence in Burchell’s handwriting, 
written on a small slip of paper and gummed into his African 
note-book, explained the difficulty and revealed the missing 
types :—“ Six insects borrowed by Mr. Hope, 3rd February,
