A single female of this distinct species was in the collection of Malaccan specimens 

 submitted to me by Dr. Staudinger.

Female. Wings above closely resembling those of the same sex of P. hc&ticm. Wings beneath pine 

 brownish ochraceous, with the following linear brownish fasciee margined with greyish : — both wings with 

 two at end of cells and two submarginal fascia*, the innermost broadest; posterior wings with two large, 

 marginal, blacliish spots, containing a few scattered greenish scales, inwardly margined with pale reddish - 

 ochraceouR, and separated by the lower median nervule. Body above more or less concolorouH with 

 wings, beneath with legs greyish- white \ legs more or less streaked with brownish.

I am indebted to Mr. J. K. Birch for a specimen of this very interesting species. 



Genus MEGISBA. 



Mojusbtt, Moore, Lep. Ceyl. vol. i. p. 71 (1881). 



This genus is allied to Polip}umtttn$ by having the first subcostal nervule of the anterior wings free 

 and not anastomosed with, nor impinging on, the costal uervure, and like that genus the posterior wings 

 possess el single filamentous tail-like appendage. The other characters relied upon by Mr, Moore- arc in 

 the anterior wings: — " first subcostal branch emitted at nearly one-half length before end of the cell, 

 second at one-third before its end, third at one-eighth, the fourth at one-half beyond and terminating 

 before the apex ; discocellulars very slender ; middle median branch emitted immediately before end of the 

 cell, lower at one-half before its end; submedian straight; hindwing convex at the apex, oblique towards 

 anal angle, abdominal margin long ; hist subcostal branch emitted at one-fifth before end of the cell ; two 

 upper median branches from a short distance beyond end of the cell. Abdomen long, reaching to anal 

 angle." 



This genus has been so recently proposed that it is impossible to estimate its area of 

 distribution, at least, until we know what species are to be included in it.
