ZEUXIDIA. 



327 



Larva long, hairy, especially about the head ; head with two short broad dentated horns, with two dark 

 transverse bars between the first and second, and second and third thoracic segments; extremity of the 

 body forked. 



Chrysalis long, boat-shaped, entire, head acuminated and bifid. 



The characters given by Fabricius of Amathusia, in his Si/stema Glossatorum, are, as usual, very vague and vinsatisfactory ; but, as lie 

 proposed the P. Phidippus of Linnajus as its only type, we can have no difficulty in applying the name to the present group, although 

 it has been differently used by several Continental writers. From Kallima and Zcuxidia it is at once distinguished by the rounded 

 extremity of the fore wings, and arrangement of the wing veins ; from the former, also, by the slender palpi and very bi*oad tails ; and 

 from the latter, by the want of the rounded dilatation of the hinder margin of the fore wings of the male, and the want of the spur 

 arising from the third branch of the median vein of the same wings. 



We are indebted to Dr. Horstleld for a knowledge of the transformations of the typical species, which he observed in Java, and 

 which are represented in his Descriptive Cataloijue of the Lepidoptera contained in the Collection of the East India Company. The 

 Caterpillar is long, with a rounded head, armed on the sides above with a pair of short, broad, palmated horns ; the body is covered 

 with minute setaj, and also thickly clothed with hairs, especially about the head ; the body is terminated with two long hirsute branches, 

 pointed at the tip. The Larva is of a pinkish grey colour ; the horns of the head edged with red, and two red bars across the thoracic 

 portion of the body ; the sides of the body above the legs are buflf-coloured. The Chrysalis is long, destitute of conical protuberances, 

 considerably boat-shaped, with the head-case long and acuminated, or rather terminated by two long slender points, thus very closely 

 resembling the transformations of Discophora. The Caterpillar is not uncommon, and is found on the Cocos nucifcra from December 

 to April. 



Our PI. LIV.* f 2. represents the male of the type, Am. Phidippus, from Java, the under side of which is of a rich fawn colour, with 

 numerous narrow, straight, pale stripes running transversely across all the wings ; and with two large ocelli, one near the outer angle of 

 the hind wings, and the other near the anal angle of the same wings. The female has the brown colour of the upper surface of the 

 wings richer, with an oblique, rather broad, fulvous buff patch, running from the costa of the fore wings beyond the middle ; as well as 

 with several indistinct buff longitudinal fascia;, and a submarginal row of fulvous buff broad crescents. A specimen of the male in the 

 British ISIuseum, from India, has the fore wings with an indistinct, subapical, oblique, fulvous bar, as well as a submarginal fascia of 

 the same colour ; the fascicle of hairs opposite the extremity of the abdomen is longer and fulvous-coloured, and the outer ocellus is as 

 large as the other. 



A splendid species of the genus (A. Amythaon) has lately been received from Sylhet, having the wings on the upper side of a rich 

 dark brown, with a pur])le tinge ; the fore ones in the male with a very broad oblique fascia of beautiful lilac ; the interior basal portion 

 of the hind wings is clothed with long, jet black, velvety scales, and there is a tuft of elongated brown haii-s opposite the middle of the 

 abdomen. The female of this species has a broad, rich, golden yellow, oblique fascia across the fore wings, interrupted near the hinder 

 ano-le with narrow brown arches. The under side of this species is buff, with rich brown slender stria; extending across all the wings. 

 The tail in this species is much narrower than in A. Phidippus.
