TThE genus Bruchus consists, in general, of small 
insects. The Bruchus granarius is found among 
beans, vetches, and other seeds, the lobes of which 
it devours. It is scarcely two lines in length, and 
is black, with the wing-shells freckled by white 
specks : the two fore-legs are reddish, and the an- 
tennaB of similar colour at the base: the thighs of 
the hind-legs are armed with a tooth or process. 
The Bruchus seminarius is a rather smaller than 
the preceding species, which it considerably re- 
sembles, but has the hinder thighs plain, or with- 
out the denticle. The larvae of these species seem 
to have been not yet observed. 
The exotic species are chiefly natives of Ame- 
rica. Among these the Bruchus Bactris is one 
of the most remarkable, and is found in the nuts of 
the Palm of that name: it is of a grey colour, with 
the thighs of the hind-legs ovate.
