LEPIDOPTERA. 



lOS 



edged with midulated gray strigEB, consisting in the middle and anal areolets of two hranches, 

 of which the anterior is interrupted, crosses the middle of the wing in form of an arch ; and a 

 very broad border verging to ferruginous passes along the posterior margin, being edged 

 internally by a waving line of a deeper tint; inner exta-emity of the margin, in the anal, region, 

 ornamented with three oblong semi-ovate intensely black spots disposed at the extreme angle in 

 a uniform connected series, covered with rich golden irrorations inclining togi-een: thorax above 

 in both sexes, irrorated with a verdigris shade ; ahdomen brown ; both these covered underneath 

 with .a tawny down ; .antenruB nearly uniformly brown ; intermediate tail with a dull grayish tip, 

 lateral tails minate, obscure. 



I have been enabled to identify this species with the Hesperia Centaiirus of Pabricius, by the examination 

 of a specimen contained in the Banksian Museum, bearing a ticket in his own hand-writing. It is closely 

 allied to the following, but its prominent distinctions are the pure purple tint of the upper surface of the 

 male, and the brilliant, pearly rings, enclosing the spots in the medial area of the fore wings Of both sexes, 

 underneath. Besides other peculiarities which appear in the detailed descriptions, the markings are more 

 pronounced in our specimens of Centauries, and the tints are more diversified. Our collection contains three 

 male and six female specimens of this very beautiful species which, as far as I have observed, has not yet 

 been figured.

The peculiarities of this species, in the upper surface, are, a most brilliant azure tint, extending 

 uniformly over the whole, and reflecting a rich silvery lustre, similar to that of Morpho Adonis, but of a more 

 saturated hue ; In the lower surface the spots and bands are edged with delicate whitish rings and lines, but 

 without any pearly lustre or metallic gloss. Tlie disposition and the character of the bands is also peculiar 

 in several points : they consist of confluent fragments, bordered by strongly undulated strlgae, appearing 

 macular, and the medial band of the hinder wings Is simple. 



My account of this species Is unsatisfactory, since we have but a single male specimen in our collection : it 

 is however in high perfection, and exhibits, unchanged, the rich brilliancy of the upper surface. The 

 figure of Cramer represents the marginal lines which confine the bands as they exist In our specimen.
