The Linnaean description of the Curctilio Betulœ , so nearly corre-sponds with that of C. Populi, that if we allow for the variation ofc olour to which all Insects are subject, a line can scarcely be drawnbetween the two species ; the most material distinction is the undersidecl" C. Betulce being of the same colour as the back; but the underside9 f C. Populi is purple, and smaller.
