Part 16

It is the largest of the Vanessæ, measuring nearly five inches across the upper wings. The surface is dull brown, with a broad common transverse band of greenish white, placed between the middle and the external margin of the wings. On the upper wings this band is composed of a double series of spots, the interior ones small and crescent-shaped, the exterior large and oval with a large black mark in the centre: on the under wings it is more continuous, with a row of white lunules externally, and two large ocelli, remote from each other, having a blue pupil and a yellow iris. The under side is much paler than the upper, and the band on the anterior wings is nearly as entire as in the posterior pair.

This conspicuous species is a native of the island of Amboina.

The surface of the wings in this pretty insect is dark brown approaching to black, with a broad band of deep red running across the centre of both wings, but scarcely reaching the anal angle, and bifid at its anterior extremity: beyond this on the anterior wings are two transverse rows of small white spots, both of them irregular; and on the hinder pair a single row-of similar spots: the notches on the margins of the wings are also whitish. The under side is much paler than the surface, but the markings are similar. Body dull black above; antennæ of the same colour, with the extremity of the club reddish. Expansion of the wings from two inches to two and a quarter.

This very elegant species, which is a native of China and the island of Java, is subject to much variation in its colour and markings. In its most ordinary state the colour of the surface is velvet-black in the male and dark brown in the female, with two large ocelli on each wing having a violet-blue pupil and a yellowish-red iris. The costa of the primary wings is generally dull white, and towards the base are two or three transverse stripes alternately blue and tawny-yellow; towards the apex are three whitish bands, the interior one broadest, the middle one interrupted by the ocellus, the third narrow and lying along the external margin. The secondary wings are surrounded by a white band divided throughout its whole length by a double undulating black line; the space between this band and the middle of the wing bluish-green in the male, a colour which scarcely appears in the female, and the anterior portion generally black in the former sex. Under side pale, the transverse stripes much elongated and six in number; the under wings greyish-brown or greyish-white, with several obscure undulating lines towards the base, with a row of four or five unequal ocelli having a blue iris in the female, but almost obsolete in the male. Body black above, greyish beneath.

The figure represents a variety of the female, the same as that delineated by Cramer.

The caterpillar, beset with branched spines, is of a black colour with numerous scattered white points, and has a white line along each side above the legs, and two rows of yellowish brown spots.

The genus Charaxes was separated from Nymphalis by Ochsenheimer for the reception of this butterfly, which may be regarded as the most beautiful inhabiting Europe. It varies in the expansion of the wings from three to four inches; the surface a rich silky brown, changing slightly with the light. Along the hinder margin of the primary wings there is a broad fulvous band, more or less sinuated on the inner side and narrowly edged with black externally, divided by eight nervures, which are dark brown ; rather beyond the middle of the wing, a transverse band of large fulvous continuous spots extends from the costa to the inner margin, and is sometimes continued for a short way on the secondary wings; the latter likewise with a posterior band, formed of contiguous spots of a fulvous colour, more or less tinged with green, preceded by a series of from five to seven bluish-green spots, commencing at the anal angle; the margin itself black, as well as the projecting angles, two of which are prolonged into tails. Beneath, the anterior portion of all the wings is rust-red, marked with spots and transverse stripes of olive-brown, encircled with white; beyond this there is a white band of a satiny lustre, bordered externally on the upper wings with dusky lunules; the space beyond these lunules is fulvous, traversed by a band of slate-grey, with a series of black spots, inclining to triangular, on the inner side of it. Beyond the white band on the secondary wings there is a row of ferruginous spots, succeeded by an olive-coloured space bearing a row of violet-blue points; the posterior band similar to that on the upper side. Head and thorax rust-brown; abdomen dull brown, with greyish hairs; antennæ black, proboscis shining rust-red.

The female scarcely differs in appearance from the male, except in having the under side of the hinder wings finely sprinkled in the middle with blue points.

“The Jasius butterfly is one of the largest, rarest, and most beautiful of the European diurnal Lepidoptera. It occurs in the southern countries of France, for example, in the neighbourhood of Lyons, the Isles d’Hières, near Toulon and Montpellier; also in Italy, Sicily, Corsica, some parts of Northern Africa, and in Asia Minor. Lefebure de Cerisy of Toulon has payed considerable attention to the metamorphoses of this fine insect. The caterpillar, which in its early stage is green, becomes afterwards of a yellowish hue, and its skin is as it were shagreened and transversely plaited. Its head is singularly armed with four vertical yellow horns tipped with red, of which the two intermediate are the longest. A yellow line passes along each side of the body in the region of the stigmata, and the back is marked with four indistinct orange spots. The true feet are black, the membranous ones green. It feeds on the leaves of the strawberry tree, and never eats except during the night. Its habits are very lethargic. During day-light it remains fixed and motionless on its favourite plant, which it resembles in colour, and thus escapes observation. The chrysalis is smooth, thick, carinated, and of a coriaceous texture, the colour pale green. Two broods or flights of the perfect insect are produced each year, the first in June, the second in September. The caterpillars of the autumnal brood survive the winter, and are not transformed into chrysalids till the ensuing May. The perfect insects are then produced in about fifteen days. These speedily deposit their eggs, which are hatched in June, and after three months occupied in the usual transformations, the second flight appears in September, and continues the race in the manner above mentioned. In many parts of France the butterfly is named the Pacha with two Tails”.
