In all tbe figures the same letters and numbers stand for the 

 corresponding markings, as fully explained in the text (see pp. 91, 

 92); m, median nervure of fore wing; m, do., hind wing; sc, 

 subcostal nervure, fore wing ; sc, do., hind wing ; 6, blue. 



Each series (except A and I) has, for convenience, been con- 

 sidered to consist normally of 15 members, 8 in the fore wing, 

 7 in the hind wing, and the interspaces have received corresponding 

 numbers. If it be borne in mind that the spaces between the 

 median and submedian nervures in the fore wing and hind wing 

 are invariably numbered 8 and 15 respectively, and that the 

 others are numbered in succession from them, there will be no 

 difl&culty in using the system, though a slight want of correspond- 

 ence between spaces and spots occurs near the extreme tip of the 

 fore wing which may occasionally make it necessary to refer to the 

 branches of the subcostal nervure by their separate names.
