LEPIDOPTERA. yj 



low, with abroad fascia of blackish-brown, extending from the middle of the costa of the fore 

 wings obliquely over the base of the hinder wings to the thorax; at the point where it meets 

 the costa commences a curved, irregularly interrupted macular fascia, consisting of diversified 

 spots and patches of blackish-brown ; exterior to this is on the fore wings a narrow brown margin, 

 regularly waving at its inner edge, bearing a row of oblong yellowish spots, which is continued 

 in the hinder wings by a series of uniform lunulas directed outwards, touching a narrow black 

 marginal streak and inclosing a series of white lineolas. Head, thorax, and body, deep blackish- 

 brown above, yellowish underneath ; abdomen banded with yellow at the sides : antenna 

 marked with delicate annuli. Tails filiform, black, tipt with white. In the female the transverse 

 band of the fore-wings approaches nearer to the costa than in the male, its posterior edge is more 

 deeply sinuated, and the hinder wings have an interrupted row of obscure yellowish lineolae, 

 parallel with the margin : the wings, in this sex, are also broader and more expanded, and the 

 abdomen is more robust. 



The first notice of this species is given by MM. Latreille and Godart, in Encyclop. Method, article 

 Papillon, p. 659. Male specimens only had been examined by these authors. Hitherto this species has only 

 been found in Java : it occurs, in considerable numbers, in the skirts of large forests ; but from the great 

 delicacy of the wings it is not easily obtained in a perfect state. Our collection contains about sixteen speci- 

 mens, several of which are females. One of the latter is represented on our plate. This species departs 

 slightly from the regular type : the wings are proportionally narrow and of great lateral expansion : in its 

 habit and marking it is analogous to the genus Nymphidium of Fabricius, but it cannot, in our opinion, be 

 separated from Lyccena. The dissection contained in our second plate was prepared by Mr. Charles Curtis 

 with great care from a male, and affords an illustration of this particular form in the genus Lyccena. Fig. 4 

 and 4, a, exhibit the exterior peculiarities of the female ; fig. 4, b, palpi of natural size and enlarged ; 4, c, 

 antenna of natural size, and with the extremity enlarged to show the excavation of the club ; 4, d, proboscis 

 male of natural size : the latter as well as the antenna? and palpi are alike in both sexes ; 4, e, fore lea of 

 the male ; 4, f, mid leg, with the spinous process of the femur.

 Wings above white, with a grayish-blue base, over which a brilliant silvery irroration, varying 

 according to the light, is thinly spread ; anterior margin of both wings blackish-brown, a border 

 of the same colour passing along the posterior margins, broader on the hinder wings, indented at 

 the inner edge, and bearing a regular series of white rings formed by crescents applied to each 

 other, the exterior being in many cases so obscure, that merely a series of lunules directed out- 

 wards is apparent : a very irregular series of square or oblong maculae passes along the inner 

 edge of the marginal border, and several maculae, more elongated, are scattered over the disk 

 and along the anterior margin of both wings. Beneath the wings are white ,- in the anterior 

 wings an oblique band of black extends from the base to the anterior margin, the interrupted 

 macular fascia and the transverse marks of the disk and anterior margins appear more promi- 

 nently
