S ?. The greenish olive-brown colonr of the upj)erside of the abdomen is liable 

 to fade into ochre yellow ; the forewing is heavier marked in the S than in the ?■ 

 The hindwing varies somewhat in the dei)th of the yellow colour. The species is 

 easily distinguished from strigilis by the much paler yellow tint of the upperside of 

 the hindwing and of the underside of the body and wings, by the more prominent 

 lobe SG'' of the forewing, the large olive black subbasal patch of the upperside, and 

 the broader brown marginal baud of the underside of the forewing, etc. 



<S. Eighth abdominal sternite mesially produced into a strong but short and 

 blnnt iirocess (PL XXII. f. 19). Tenth sternite (PI, XXIII. f. 3) produced into a 

 lolie which is somewhat narrowed towards the end, whicli is almost evenly 

 rounded, the mesial sinns being, however, traceable in an anal view. The jiatch of 

 modified scales on the clasj)er (PI. LVIII. f. 31) broader dorsally than laterally, 

 larger than iu strigilis ; harpe not raised above the jilane of the clasj)er, having 

 neither distinct ridges nor processes ; it is sei>arated from the clasper by a furrow, 

 and is triangular in shape (PI. XXXI. f. 2). The penis-sheath is jirovided dorsally 

 by a short apical ridge, which is slightly dentate, and curves pro.ximad into the 

 interior of the slieath (PI. XXX. f. Kl). 



? . Proximal edge of vaginal orifice less elevate thiin iu strigilis, hinder wall 

 of cavity mesially carinate.
