110 Insects. 



been described by Godart, or of Fabricius having described any s})e- 

 cies so neariy allied to it as his P. Curias. By an examination of the 

 original specimen of P. Curius in the Banksian cabinet, which, how-| 

 ever, is 7iot labelled in the hand-writing of Fabricius; and also of' 

 Jones's drawing from which Donovan's iigm'e was taken, my suspi- 

 cion was turned to certainty ; and it only remains for me to endeavour 

 to point out to other entomologists the characters by which the two 

 species may be distinguished. 



The Fabrician description* is alone quite sufficient to point out one 

 decided character of the true Curius, but does not indicate all the dis- 

 tinctions between the two species ; and I shall therefore give a more 

 detailed account of them, using the Fabrician name for the Northern 

 Indian species, to which of right it belongs, and Zinken's name, Me- 

 ges, for the Javanese species commonly known as L. Curius. 



In L. Curius the band which crosses the middle of the anterior 

 wing is externally curved, and of an opaque white towards the base 

 of the wing, but the outer half is perfectly hyaline, with the nervures 

 black. In the white portion of the band the nervures are concolorous, 

 except the subcostal, which is black. The hyaline space crossed by 

 the black nervures which occupies the outer portion of these wings, is 

 smaller than in L. Meges, the black border being broader, especially 

 at the apex, where it leaves only a small oval hyaline spot between 

 the last branches of the subcostal nervure. The band of the posterior 

 wings is narrower than that of the anterior, and of the same opaque 

 white as that portion of the latter to which it corresponds. 



In L. Meges, the band of the anterior wings has its margins more 

 nearly parallel, is of a glaucous hue, and has all the nervures conco- 

 lorous ; that of the posterior is rather broader and of the same colour, 

 and whilst in L. Curius it is the inner margin of this band which most 

 nearly coincides with that of the anterior wings, in L. Meges it is just 

 the reverse. The anal angle of the posterior wings and the base of 

 the tails are less powdered with whitish in L. Meges than in L. Curius. 



The accompanying woodcuts very nearly express the characters 

 which distinguish the two species, though perhaps there is rather too 

 marked a difference in the form of the posterior wings, which however 

 are much more indented in L. Curius than in L. Meges. It will be 

 needless to give a formal description of the two species, I shall there- 



*" Alis caudatis, concoloiibus, atvis; anticis fasciis dimbus hyalinis ; posticis unicaj 

 alba : and it is latlicr singular to read this below Godart's specific character — "" alis 

 vsubconcoloribus, nigris, /aici^ communi (jlaucti : anticis auto apieein liyalinis."
