No. 62._ ---- Entomologists of the last century classed all day-flying Butterflies in the Genus _Papilio_. But this denomination has been restricted, of late years, to such as possess six long perfect legs; very short palpi, and the anterior shanks spined near the middle. Now this group is so peculiarly distinct, and comprises within itself such numerous variations of form, that we have always viewed it as pre-eminently calculated to put to the most severe test any arrangement, the principles of which are conceived to be those of Nature. The _Papilionæ_ have consequently, for many years, engaged much of our attention. Baffled in numerous attempts to understand their arrangement, it was only upon applying those principles of the natural system, which we have detailed in _Northern Zoology, vol. 2_, that their true affinities became apparent. At present we shall only apprise the Entomologist that the divisions above named are _circular groups_, and the result of strict analysis. The sub-genus _Chlorisses_, in reference to Ornithology, is a scansorial type. The present Insect, figured from the male sex, is one of the most beautiful butterflies of India. General Hardwicke presented us with specimens from Nepaul; and we have since received others from Java. The typical species is _Papilio Agamemnon_, where the green colour is broken into round spots. The most extraordinary circumstance, however, which belongs to the group, is this; that although a sub-genus, it yet contains within itself _subordinate_ types of form, representing all the higher divisions. The only ornithological group we have yet ascertained as possessing this property, is the sub-genus _Parus_ (proper). * * * * * * [Illustration: JASIA _Athama_.] JASIA Athama, _Athama Butterfly._ ---- Tribe, Papiliones. Family, Nymphalidæ. _Nobis._ SUB-GENERIC CHARACTER. _Lower wings_, acutely bi-caudate; _Antennæ_, short, gradually thickening into a lengthened, cylindrical club, the tip nearly truncate; _Palpi_, projecting, and longer above, than is the head; their tips acute; their joints concealed by compact scales.
