Bruclii. I have already prepared materials for dividing them more natu¬ 
rally than by the presence or absence of a spine upon the thighs ; and I 
hope I have found sufficient characters in the structure of the thighs and 
tibiae, which, as far as I have observed (combined with a peculiar shape of the 
body, thorax, and antennas), are of real importance, both scientifically and 
naturally. Nevertheless, as my investigation is not completely terminated, 
I will not here propose for the above-mentioned forms new generic names, 
although there would be no difficulty in characterising them : but I in¬ 
sist, in my descriptions, upon certain characters which will help the reader 
to recognise to what new generic form the species pertain. I therefore 
trust the extension of some of the following descriptions will be pardoned.

Nearly allied to Br. Lebasii, but differing, as far as T can judge from 
a single specimen, in having the thorax broader, more convex, the poste¬ 
rior angles less acute, its punctures less deep and rugose, 1 wanting the two 
1 I must here observe that Schonherr’s description of Br. Lebasii 
(v 25) does not agree completely with the nature of the punctures of the
