106 A Visit to Damma Island : 



show when magnified a large proportion of fine long scales 

 among the broader ones. 



Two pairs of spines are present on the hind tibiie. 



The species I dedicate to the enthusiastic collector to whose 

 efforts the National Collection is indebted for many entomo- 

 logical treasures. 



Ocijhadistes Walkeri^ sp. n. 



Expanse of wings 22 millim. 



The general scheme of marking and coloration is much as 

 in manias^ Felder, but the orange markings of Walkeri are 

 not so red as in Felder's species, especially on the underside, 

 where the brownish markings of mamas are represented by 

 an ashy green shaded to a black-brown on the inner margin 

 of the fore wings, and the orange markings are of a pale 

 sienna colour on the fore wing, and on the hind wing inner 

 margin ochreous, shaded to the orange of the upperside 

 markings. 



Antennce dark black-brown, shaft semi-ringed with ochreous, 

 club dark black-brown above, ochreous below, crook dark ; 

 palpi golden yellow towards the top, almost lemon-coloured 

 below ; this pale hue extends below the thorax and the 

 abdomen ; forehead with golden-orange scales ; collar, 

 patagia with scalings of similar colour, especially large on the 

 latter. 



Thorax thickly covered with yellow hairs of greenish 

 iridescence. Abdomen golden orange. 



Fore wings golden orange; costa black-brown, outer margin 

 with a black-brown border from apex to inner angle, averages 

 nearly one third the breadth of the inner margin, but reduced 

 by intrusion of the orange ground between veins 6 and 4 to 

 about half that width, below and to the side of the discoidal 

 cell the dark colour stretches to an almost similar width, at the 

 side and below vein 6 sends out a spur which sometimes 

 reaches the dark border; dark scalings occur below vein 1, 

 and from the costa opposite the end of the cell extends a 

 small spur of dark, which may sometimes anastomose with 

 the dark bounding the cell, thus leaving a small spot of the 

 orange ground isolated. 



Hind wings of similar coloration, but the orange is slightly 

 deeper in tone and its borders much more irregular than in 

 mamas, running out along the veins, especially opposite the 

 end of the cell, and sending a spur towards the costa along 

 vein 7 : the orange fleck in the cell is more conspicuous tlian 

 in mamas. 



Below the markings show more faintly ; the black-brown
