THE QUINARY SYSTEM. 



Mr. W. S. MACLEAY, the author of this system, pro- 

 poses to arrange insects in circular groups of fives, so 

 as to place those which have the nearest resemblance, 

 or (as he terms it) affinity, contiguous to one another 

 in their several circles. We shall here give from the 

 Horse JCntomologicse his arrangement of Clairville's 

 Mandibulata, with translations^&c., of his terms.
