laterally inclined projection at one-half, and by the form of the fulcrum, the apex 

 of which is dilate and spatulate, the dorsal surface densely and coarsely scobinate 

 and tipped with a stout spine equal in length to the width of the scobinate, pad-like 

 apex. 



In the female genitalia the sterigma is asymmetrical and laterally crenulate; 

 the corpus bursae is wholly membranous.

$ $ (PI. 107, figs 955, 956). Non-hyaline terminal area of wings densely irrorate with light 

 brown (pi. 6, D7, raw sienna) to brown (pi. 7, E6) ; basal area of fore wing at posterior margin 

 and discal spot on each wing similarly coloured; dentate subterminal fascia on each wing a 

 shade darker and slenderly edged distally with glossy greyish orange; cilia chequered greyish 

 orange and dark grey. Underside of non-hyaline terminal area of wings: apical area of fore 

 wing, from costa to vein M v white to light buff; remainder of wings greyish orange densely 

 suffused with dark brown, as illustrated (PI. 107, fig. 956). 



In the male the hind tibia is dilate with a short buff hair-pencil.

This and the following species, erato, were tentatively synonymized by Gaede 

 (1915 : 116), though at the time he drew attention to the differences between the 

 two in the colour of the underside of the wings. 



In ilaria the non-hyaline area of the upperside of the wings is densely irrorate 

 with brown (pi. 6, D7, raw sienna to pi. 7, E6); in erato this area is greyish orange 

 (pi. 5, B6-7, apricot). The underside of the non-hyaline terminal area of the 

 wings is more extensively suffused with dark brown than in erato. 



Although the ratio of the longest pectinations to the diameter of the shaft 

 appears to differ little between the males of the two species, the pectinations of
