By the Hon. J. L. Warren. 



(Plates CVI.-CVII.) 



There occurs in this country a widely-distributed group of septal 



Brambles, which has long proved a severe crux to the students of this 



difficult genus. This shades ofi' on one side into casius, on the 



other it gradually passes into cori/lifolius, while it has also a strange 



cross-alliauce with fusco-aier and infestus, generally reckoned as Koeh-
