32 RIIOPALOCERA AFRICA AUSTRALIS. 



Expands 1 in. 11 lin. — 2 in. I lin. 



$ . White ; with black borders. Fore-wing : a more or less 

 distinct spot at extremity of discoidal cell ; on hind-margin 

 a broad, black band, widest at apex, containing about six 

 white, sub-triangular spots, lessening towards anal angle. 

 Hind-wing : a broad black band along hind-margin, con- 

 taining traces of almost obliterated whitish spots ; a small 

 blackish spot on costa before apex. Under-side. — Similar 

 in marking to upper-side ; a more or less distinct disco-cellu- 

 lar spot in both ivings. Fore-wing : base tinged with pale 

 yellow ; spots in hind-marginal band larger and more distinctly 

 defined than on upper-side. Hind-tinng : pale-yellowish ; 

 costa from base, and space between median and sub-median 

 nervures, tinged with orange ; hind-marginal band containing 

 a row of spots along its outer portion ; black spot on costa 

 before apex united to marginal band. 



? . " Larger than $ , violaceous-white, the border wider. 

 Fore-wing : base more or less powdered with blackish ; costa 

 black, united to the disco-eellular spot, which forms a short, 

 oblique, very dark band. Under-side. — Fore-whig : base 

 often saffron-yellow. Hind-wing : violaceous-white, rayed 

 with saffron-yellow along nervures. Border of both wings 

 divided as in $ ." 



This description of the ? insect is from Dr. Boisduval's 

 " Species General des Lepidopteres." He further adds, 

 "Specimens from Bengal usually have the under-side of 

 hind-wing greenish ; those from Nubia are often of an 

 ochreous-yellow above, and deep yellow-ochre beneath." 



This species is very closely allied to P. Severina, of which I am inclined 

 to think it only a variety. The principal dilTereuces from it that Severina 

 presents are these, namely : distinct ichite spots on upper-side of hind-mar- 

 ginal band, and the nervures on under-side of hind-whig always more or less 

 clouded with black. I only here allude to the male insects, not haviug seen 

 a female of P. Creona; but, from what Boisduval states of the Nubian 

 varieties, I have little doubt but that this sex would confirm me in the 

 belief of the species being identical with Severina.
