arising on posterior margin near tornus (not curving basewards) and 
running straight across the wing to costal margin 1-2 mm. before apex ; 
termen dusted with brown to a width of 1 mm. ; the margin itself with 
dark spots between the veins. Hindwing less pure white, being very 
finely and vaguely dusted with brown. Under surface very like that of 
pactolaria ; forewing suffused with brownish, the bands very feebly 
showing through in a greyer tone, hindwing white. 
Waterval (Zoutpansberg District), Transvaal, 9th December, 1903.. 
Eupithecia f estiva, n. sp. (PL XXV, Fig. 21). 
cJ, 15 mm. Head and thorax light ochreous-brown, somewhat mixed 
with white. Antennal ciliation minute. Abdomen rather long and pointed, 
very varied, its base, a narrow mediodorsal stripe to beyond middle and 
a lateral one from before middle to anal end, concolorous with thorax; 
a bright ferruginous patch laterally on 2nd-3rd abdominal (recalling 
Melanthia ustiplaga Warr., Nov., Zool., VI, p. 298), and some ferruginous 
ventrally in posterior part ; the rest predominantly dark grey ; dorsal 
crests scarcely developed. Forewing with termen not so oblique as in 
many of the genus ; light ochreous brown, a good deal mixed with bright 
ferruginous ; basal patch dark grey costally, its boundary indicated by 
cuived, strongly oblique whitish line ; a broad median band, mostly dark 
grey, especially at costa, in the middle and posteriorly somewhat mixed 
with the ground-colour, and with an irregular patch of the ground-colour 
around the large black discal spot ; boundary -lines of this band fine, 
white, the proximal oblique outwards from nearly two-fifths costa, acutely 
angled at SC, then parallel with termen, but with a curve inwards in 
submedian area ; the distal from nearly two-thirds costa, forming a gentle 
outward curve from SC 5 , posteriorly about parallel with termen ; sub- 
terminal line white, distinct, nearly straight from near tornus to near costa, 
then slightly inbent ; termen with dark spots between the veins ; fringe 
with a pale line at base. Hindwing grey, paler in cell and traversed by 
pale waved lines, the proximal ones only indicated at the inner margin. 
Forewing beneath more greyish-suffused from base to postmedian and 
with greyish bands proximally to the subterminal and to the termen ; 
sub terminal line indistinctly pale ; a dull ferruginous tinge in the rest of 
the distal area. Hindwing beneath grey, traversed by whitish lines. 
Barberton, 29th January, 1911. 
The coloration somewhat recalls that of the European E. gueneata 
Mill., though slightly darker, duller, and less rufescent. 
Eupithecia gradatilinea, n. sp. (Pl. XXV, Fig. 22). 
$, 20 mm. Face and palpus fuscous. Thorax above concolorous 
with forewing, abdomen much darker than hrndwing, both beneath pale. 
Forewing pale ochreous-grey dusted with dark-grey (colour of E. castigata 
Hbn. ; both wings very slightly narrower than in fhat species) ; cell-mark 
black, elongate (length of DC 2 - 3 ); costal margin with some dark dots 
and spots, especially at the beginnings of the lines ; some dark spots at 
base ; lines rather indistinct ; subbasal fine, bluntly angled subcostally ; 
an intermediate line and the antemedian scarcely discernible, apparently
