J40 DESCRIPTIVE CATALOGUE. 



Papilio Valeria. Cram. pi. 85. fig. A. (Variety of the male.) 

 Pieris Valeria. MM. Latr. et Godt. Enc. Meth. Hist. Nat. ix. 154. 

 Our collection contains four male and four female specimens from Java. We have also several continental 

 specimens, in which, however, the sexual distinction is less apparent. The latter possess that peculiarity 

 assigned to this species in the description given of it in the Encyclopedie, having a series of white dots in the 

 marginal border of the fore-wings, while our description represents the insect agreeing strictly with Cramer's 

 figure, which is considered as a variety by MM. Latr. and Godt., having in the male a simple posterior 

 border in all the wings. Our insect possesses another peculiarity, the colour inclining more to bluish than 

 to greenish-white. The remarkable difference in the painting of the sexes is also to be considered in the 

 description of our species. In the female the border is undefined spreading over the entire disk, and even 

 to the base, while the intermediate white patches are slightly covered with brown irrorations, over which, 

 towards the base, a saturated yellowish or grayish shade is thickly spread. Indeed the female assumes 

 the external habit of an Euplcea ; but in the modifications of the nervures it closely agrees with the male. 

 Bearing in mind these peculiarities of the Javanese insect, it remains for future inquiries to determine 

 whether it be not specifically distinct from the continental species.

 Wings snow-white, somewhat glossy and of a delicate texture, anterior having on both sides a large 

 subangular mark in the medial area a little behind the disk, with the obliquely defined apex 

 of the upper surface blackish brown ; hinder-wings immaculate : underneath fore-wings 

 with the costal margin as well as the apex and base irrorated with ash-gray; hinder-wings 

 having the whole surface delicately variegated with the same tint, slightly verging to green; 

 three more distinct undulated strigse passing at regular distances parallel with the posterior

Haec species a Papilione Alcesla Crameri nisi cauta comparatione distingui non potest : differt tamen alis 

 omnibus brevioribus magis abrupte rotundatis ; ut et notis sequentibus : anticarum nempe macula discoidali 

 obscure fusca, nitore hyalino prorsus carente ; posticarum pagina tota cinereo nebulosa in virescentem vero-ente 

 strigisque tribus distinctioribus undulata. 



A specimen of this insect, preserved in the Banksian cabinet at the Linnean Society, is marked with a 

 ticket bearing the name of Papilio Xiphia in Fabricius' own handwriting. It also appears with this name 

 both in the Species Insectorum and in the Mantissa, but in the Entomologia Systematica Emmendata 

 published at a period subsequent to those works, we find the name of Nina applied to this insect, in order to 

 prevent a « double emploi " of one name in the genus Papilio, Xiphia having previously been given to one of 

 the Nymphales.
