DISCOPHORA. 329 



A mule specimen of the type of this genus, Z. Luxerii, in the British Museum, has supplied the chief of the generic characters given 

 above. It has the fore wings marked with a very broad lilac bar, extending in a somewhat curved direction from the middle of the 

 costa to the anal angle ; the outer angle of the hind wings marked with a broad patch of lilac, and the middle of the discoidal cell with 

 an elongate-oval patch of brown hairs ; the tail of the hind wings is also considerably acuminate. The under surface is purplish 

 brown, with dark clouds, and with the dark streak across all the wings beneath slightly bent towards the base of the fore wings, at its 

 junction with the costa, and the ocellus on the disc of the hind wings next the costa is very much smaller than the one towards the 

 anal angle ; the extremity of the fore wings is also marked with a small pale oval patch. Dr. Boisduval possesses the female of this 

 species, the wings of which on the upper side are brown, darker in the middle of the fore wings, beyond which is an oblicjue bluish 

 white fascia, obliterated towards the anal angle, where are three obscure fulvous spots, the hind one occu|)ying the anal angle ; the hind 

 wings are brown, with an internally subdentatc dull fulvous margin. Beneath it agrees with the male, but is more uniform in its 

 colours. 



The British IMuseum also contains both sexes of an allied species from India, the male of which is distinguished by its more 

 acuminated fore wings, destitute of the pale spot near the tip ; the broad lilac bar of Z. LuxcM'ii is replaced by a much narrower and 

 more cui-vcd blue bar. The hind wings have the tails much less acuminated ; the lilac patch of these wings is replaced by a very broad 

 blue fascia, which extends to the anal angle ; the middle of the discoidal cell has an elongate-ovate smooth spot destitute of hairs (which 

 may, however, have been abraded) ; the dark brown streak across all the wings is curved towards the tip, at its junction with the costa, 

 and the ocellus next the costa is very much larger and more distinct than that near the anal angle. 



The female of this species (represented in our PI. LII. fig. 1. as the female of Z. Luxex-ii) has the outer half of all the wings tinged 

 with a blue gloss, with an oblique bluish white broad bar extending from the middle of the costa to the third branch of the median 

 vein, where it is broken up into three rows of spots ; the interior conical, the middle row nearly rounded, and the outer ones semicircular. 

 There is a slight trace of these spots continued along the outer half of the hind wings. 



Dr. Boisduval possesses another species from Java, which has the wings on the upper side brown, with the tips paler ; the fore wings 

 with a subapical indistinct row of fulvous dots. Beneath, the wings are brown, with a dark subapical streak across all the wings, 

 reaching nearly to the anal angle, and with two ocelli beyond the middle of the hind wings ; the anal angle of which is produced into 

 an obtuse tail, with a dark spot near the tip beneath. 



The beautiful butterfly figured by Cramer under the name of P. Aurelius appears to me to be a female of this genus, from the 

 general resemblance of its markings to those of the female of Z. Doubledaii ; it is of tiie greatest rarity, no specimen of it existing in 

 any cabinet in England or France, so far as I can learn.

DiscoPHORA Boisduval., E. DouhUdmj. 

 McERA and Zeeynthia Hiibner. 

 Morpho God'., Hor.sfield. 



Body robust, very woolly ; fore wings acute at the tip, with the apical margin truncated ; males with a silky patch in 



the middle of the hind wings on the upper side. 

 Head rather small, woolly, with a small woolly frontal tuft. 

 Eyes large, jjrominent, broadly oval.
