The examples which have formed the basis of the above Cata- 
logue are from the cabinets of my friends Messrs. Baly, Bonvouloir, 
Chevrolat, Deyrolle, Dohrn, Fry, J. Gray, Lacordaire, Miers, Murray, 
Saunders, Schaum, Thomson, and Waterhouse, with the addition of 
the collection of the British Museum: the material entrusted to me 
for examination has been or is being returned to its respective 
owners. JI am glad to be able to acknowledge the special advantage 
that I have derived from the collection of M. Chevrolat, not so much 
on account of the range of species contained in it (though this is 
considerable), as by reason of the care and exactitude which had 
manifestly been given to the separation of different species, and of 
the same species from different localities. With regard to the fore- 
going arrangement of the group, I may add that probably some of 
the forms which in it are made to constitute separate species may 
ultimately prove to be but sexual varieties. I have a suspicion that 
Gdionychis 276 dispar and 23 atriventris are the two sexes of the 
same insect, also 227 variolaris and 223 dilecta. As at present, 
however, there is no absolute proof of this, I have had no alternative 
but to register them provisionally as distinct species.
