“ The species in short, in every stage, exemplifies the truth of that fundamental law of nature which we have elsewhere so fully illustrated, viz. "that every natural group, contains representations of all others in the same class," following each other precisely in the same series: thus establishing a truth which has long been suspected, but not before demonstrated, that the laws of variation are precisely the same in every group throughout the animal kingdom. ”

“ Every entomologist, upon looking to the perfect insect, will immediately be struck with its resemblance to the long-winged Heliconian Butterflys, and to the genus Euplœa, which is the Erycinian type of that family. ”
