of either, although I believe that D. Alcippiis has been taken in Europe. The larva, which 

 feeds on Asclcp-as fruticosa, is pale violet, with black and yellow transverse stripes. The 

 3rd, 6th, and 12th segments are furnished with a pair of black elastic filaments on the 

 back. They are crimson at their base, and the front pair is the longest. The butterfly is 

 figured at PI. 11, Fig. 5. {D. Erippus, Cram., var. Arcliippus, Fabr., measures 4 inches or more 

 across. The tip of the fore wings is less broadly black, and is irregularly spotted with fulvous, 

 or white in the typical Erippns, instead of being crossed by a white band. The colour is 

 deeper fulvous than in D. Chrysippiis, and the veins of the wings are more or less broadly 

 black, both above and beneath. D. Erippns is South American, and the variety ArcJiippiis is 

 one of the commonest butterflies in North America. We notice it here, because it has not 

 only spread over almost all the Pacific Islands, from the Sandwich Islands to Java, within 

 the last few years, but no less than three specimens were taken in England in 1S77, so that 

 it is highly probable that it may become naturalised in Europe in a very short time, if the 

 larva is capable of feeding on any indigenous plant. The larva is whitish, transversely fasciated 

 with black and yellow, and has two pairs of blackish fleshy processes, situated on the 3rd and 

 1 2th segments, of which the first are the longest. It feeds on American species of Asclcpias.) 



fa:\iily v.— satyf;di^. 



Large or small butterflies, generally black, brown, or tawny, and occasionally white. They 

 have nearly always black eye-spots with white pupils before the hind margins, which are often 

 placed on a pale band, or upon pale spots. The wings are rounded, and the hind margins are 

 either entire or scalloped. The palpi are short, and bristly beneath ; and the front pair of legs are 

 very small and rudimentary. The larvre are clothed with fine, short hair ; the tail ends in a small 

 fork, and the head is round. They live chiefly on grasses. The pupaa are thick and truncated, 

 and are either suspended by the tail, or are formed on, or in, the ground. 



GENUS I. — IIIPrARCHIA (FABR.). 



Middle-sized or large butterflies, with broad wings. The upper side is brown or black, and 

 there is generally a white or yellow band near the hind margin. There is a moderately large eye 

 near the tip of the fore-wings, and frequently a second towards the hinder angle, often with two 

 white dots between them ; and a very small eye towards the anal angle of the hind-wings. The 

 hind-wings are dentated, and are marbled beneath with pale and dark. The antennae are gradually 

 thickened, or terminate in a distinct club. The larva; are thick in the middle, and tapering at both 

 ends, with pale and dark longitudinal streaks. They hybernate, and live till June in a very retired 

 manner. The pupx are formed in a hollow on the surface of the ground, or under stones. The 

 butterflies are found more in Central and Southern Europe than in the north. They appear in 

 July and August, and generally settle on the ground, or on the trunks of trees. 



I. H. Circe (Fabr.). — Dark brown, with a broad white band near the margins, which is broken 

 into spots on the fore-wings. A round black spot, with a small white pupil on the under side, 

 stands on the extremity of the band near the tip of the fore-wings, and there is sometimes a 

 smaller one on the third white spot below the first. On the under side the band is more 

 continuous, being only interrupted beneath the eye. There arc two white spots near the costa of 

 the fore-wings, and another on the costa of the hind-wings (which are dusted with grey), and a
