LEPIDOPTERA. jq 



middle of the costa ; posterior, surrounded by an intensely black marginal thread ; fringe of 

 both pairs grayish brown, near the anal angle, at the caudal appendage a lunular-oblong black 

 spot, bordered externally by an obscure white thread extending to the anal angle : underneath 

 the wings are yellowish-brown with a straw-coloured shade and transversely marked, in the 

 fore icings with seven, and in the hinder wings with nine very delicate yellowish strigse covered 

 with a faint golden lustre ; three being marginal and continued through both pairs ; the anterior 

 wings are further marked, in the space comprised between the middle and the marginal series 

 with two pairs of strigae, one short consisting of two lines parallel to each other immediately 

 on the disk, the other extending across the whole surface in an angular curve, composed of 

 short lines somewhat flexuose between the longitudinal nerves, with a sudden inflection on the 

 disk, by which the posterior portion is directed towards the short pair ; viewed together as 

 arranged on the wing, these strigas exhibit a figure somewhat resembling the letter Y : the 

 surface of the hinder wings bears also three pairs of strigas ; the first at a small distance from 

 the base, the second in the middle stretching across the disk with a curve at the interior margin, 

 the third posterior to this and terminated at the anal ocelli ; they are individually composed of 

 parallel interrupted portions ; three ocellate spots are at the posterior margin near the anal 

 angle ; the exterior one large, nearly circular, abruptly terminated behind by a streak of silvery 

 irrorations and surrounded interiorly and at the sides with a narrow rufous iris ; intermediate 

 ocellus reniform, of a most intense tint on the lobe touching the extreme ocellus, which is larger 

 and more distinct than in the related species ; the two last ocelli are united at their internal edge 

 by a silvery lunule bordered with a rufous streak. Tails black, tipt with white; antenna: 

 obscurely banded, body, blackish above, white underneath. 



The species last enumerated is strikingly distinguished from all others belonging to this group, by the 

 brilliant blue or sea-green tint on the upper surface : our collection contains two male specimens. 



The species named Lyccena Atratus, although clearly distinct from the other species contained in this 

 catalogue, and, agreeably to my examination, from all the individuals enumerated in the 9th volume of 

 the Encyclopedic, cannot be identified with Cramer's figure of P. Atratus, without some uncertainty : it 

 agrees with that species in the arrangement of the subcostal dots, which afford a permanent distinction in 

 all the species of this section which I have examined, and in the direction and character of the strigse of 

 the forewings : but its final determination requires further comparisons. P. Atratus is cited in the Encyclo- 

 pedic, as the female of Pol. Celerio ; but since we have several individuals of both sexes of that species 

 from Java, and since P. Atratus possesses various characteristic peculiarities, I have been reluctant to 

 adopt that opinion. 



Of Lyccena Pavana, a single pair, in perfect preservation, is contained in our museum ; this species is 

 readily distinguished by the regularly tranverse arrangement of the striga? in both wings. 



The species first enumerated in this section have required, on account of their near resemblance and 

 similarity of upper surface, a more copious description than will generally be found necessary. Mlianus 

 and Celerio are two original names of Fabricius ; but his descriptions are not sufficient for the clear discri- 

 mination of the species at the present period. Some uncertainty therefore remains, as to the real 

 application of these names, to the species contained in this catalogue, and I have consequently annexed a 

 query. One specimen contained in the Banksian cabinet, with the name of Celerio, in the hand-wntmg 

 of Fabricius, belongs toMlianus of this catalogue and of the Encyclopedie. I have been more minute. 

 in the description of Lye. Mlianus, as it is subject to greater variations in the marks on which the 

 specific distinction is founded, than either Celerio or Elpis. My observations on this species are chiefly 



founded
