6 ?. The greenish olive-browu colour of the npperside of the abdomen is liable 

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

 The hiudwing varies somewhat in the depth of the yellow colour. The s]>ecies is 

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

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

 lobe SC'' of the forewing, the large olive black subbasal patch of the ujiperside, and 

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



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

 bluut process (PI. XXII. f. 19). Tenth steruite (Pi, XXIII. f. 3) produced into a 

 lobe which is somewliat narrowed towards the end, which is almost evenl}' 

 rouuded, the mesial sinus being, however, traceable in an anal view. The jiatcli uf 

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

 larger than in strigilis ; harpe not raised above the j)laue of the clasper, having 

 neither distinct ridges nor ])rocesses ; it is separated from the clasper by a furrow, 

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

 by a short apical ridge, which is sliglitly dentate, and curves proximad into the 

 interior of the sheath (PI. XXX. f. IC).
