224 MESSES. H. J. EL WES AND JAMES EDWARDS : 



! PlRDANA DISTANTI. 



Pirdana distanti, Staudinger, Iris, ii. p. 141 (1889). 



Pirdana pavona, de Niceville, Jour. As. Soc. Beng. 1895, p. 540. 



Hab. Malacca (fide Staudinger) ; Labuan (fide Staudinger, in coll. Elwes) ; E. Pegu, 

 Perak (Dolierty) ; 1 Sikkim (Lang, fide de Niceville); Buitenzorg, Java (Piepers). 



This species seems constantly distinct from hyela, though its geographical range 

 covers that of hyela. It is probably the species referred to from Sikkim by de 

 Niceville in our description of P. rudolphii.

 recurved. Palpi appressed ; third joint short, conical, almost concealed. Fore wing
