B. Wings with two rows of cells between the short sector and the supple- 
mentary sector next below; those of the male and homceochromatic 
female with extensive colouring (brownish-yellow, young, to blackish- 
brown, adult), whose outer edge is halfway between nodus and stigma ; 
wings of the heterochromatic female otherwise coloured. . . + + + 1. funerea. 
BB. Wings with one row of cells between the short sector and the 
supplementary sector next below; those of the male and homco- 
chromatic female crossed by a band, brownish-yellow (young) to blackish- 
brown (adult), whose outer edge is at, or close to, the inner end of the 
stigma; wings of the heterochromatic female otherwise coloured. . . 2. umbrata. 
AA. Wings with one row of cells between the subnodal sector and the 
supplementary sector next below. 
C. Hind wing with sectors of the triangle arising from the same point * ; 
internal triangle of the front wing three-celled ; wings, at least the hind 
pair, more or less coloured at base. 
D. Genital lobe truncated obliquely at about 45° with the vertical, 
anterior angle of the truncation the more prominent f ; vulvar lamina 
about half as long as the lateral margin of abdominal segment 9. 
E. Frons yellowish to reddish (¢) or brownish ($) superiorly, 
shaped as in unimaculata, infra ; wings of male ochraceous at base 
for entire width, this colour deepening in tint with age and reaching 
out as far as third to sixth antecubital on the hind pair, as far as 
arculus to third antecubital on the front; wings of female yellowish 
at base, on the hind out as far as the origin of A, to distal angle 
of triangle, on front as far as submedian cross-vein to arculus ; 
genital lobe more prominent than hamule . . . - - . . . 38. ochracea. 
EE. Frons metallic blue superiorly in both sexes, this colour smaller in 
extent in the female. 
F. Males with hind wing blackish-brown at base out as far as first to 
third antecubital and the corresponding level in the median and 
submedian spaces, thence retreating to the anal angle without 
touching the hind margin; front wing with basal brown streak 
in subcostal space to first antecubital or less and a spot behind 
the submedian vein out to the submedian cross-vein and back to 
hind margin, or with hardly any basal brown; basal brown of 
both wings bordered distally with chalky-white ; frons flattened 
superiorly, its superior and anterior surfaces forming an obtuse 
angle with each other when viewed from the side; hamule and 
genital lobe subequally prominent. Females with yellow at base 
of hind wing out to the level of the first antecubital. . . . . 4. erichsoni? 
* Some specimens of berenice and minuscula, species belonging properly to CC, have these sectors as in C; 
the other characters given will usually enable such to be detected.
