JL HE 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- 

 tennas of similar colour at the base: the thighs of 

 the hind-legs are armed with a tooth or process. 



The Bruchus semmarius 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.
