As ab. albimacula, n. ab. (Pl. XXV, Fig. 37), I describe a $ 
(27 mm.) from Three Sisters (20th February, 1911) in which the distal 
area above is more confusedly marked, but contains on forewing a large 
quadrate white marginal spot from before R 3 to behind M 1 and on the 
hindwing a smaller, vaguer one, both also reproduced beneath. As I have 
not seen any other $, it is just possible (though unlikely) that this will 
prove the normal form of that sex. This particular specimen also differs 
from the type in still blacker median band, postmedian of forewing more 
deeply incurved in posterior half, a more ferruginous shade proximally to 
the sub terminal, more infuscated terminal area, etc. 
Ectropis ohliquilinea, n. sp. (PL XX Y, Fig. 38). 
5, 38 mm. Face flat, dark fuscous. Palpus short, fuscous. Vertex 
and antenna concolorous with wings ; occiput and collar more fuscous. 
Thorax dorsally a good deal mixed with fuscous, abdomen irregularly 
belted, in great measure corresponding to the markings of the hindwing. 
Forewing rather elongate, costa straight except at extreme base and apex, 
termen very slightly curved, rather strongly oblique ; SC 1 " 2 coincident ; 
ground-colour whitish, with a very slight tinge of purple and strongly 
dusted with fuscous ; lines nearly black ; first from posterior margin 
1*5 mm. from base, extremely oblique to cell-fold 7 mm. from base, here 
becoming obsolete ; fairly direct, but minutely denticulate on the veins 
und with extremely shallow lunules between ; almost the entire area 
proximally to this line, and extending to costa fuscous ; discal mark 
present not conspicuous ; median line weak, very near postmedian ; post- 
median parallel with antemedian and similarly formed, the teeth rather 
stronger ; from hind margin almost at middle to SC 5 scarcely more than 
2 mm. from termen ; a second fuscous band (traversed proximally to its 
(Centre by a darker shade) between this line and the subterminal, continuing 
{narrowing) to termen between SC 5 and R 1 ; subterminal line white, 
rather distinct (except anteriorly), irregularly lunulate. Hindwing con- 
vcolorous with forewing, no antemedian line ; median more distinct than 
on forewing, from inner margin a^ two-fifths, slightly curved, losing itself 
about at SC ; discal mark a lather irregular, indistinct ocellus (pale with 
darker circumscription) ; postmedian from inner margin at about two- 
thirds, nearly straight (faintly curved and denticulate) to R 1 , here angled, 
then lunulate-den tate to costa 2 or 3 mm. from apex ; succeeding band 
and subterminal line as on forewing, both reaching costa. Both wings 
beneath paler as far as postmedian (dark-spotted costally), with large, 
distinct, rounded black cell-spot ; postmedian of forewing as above, of 
hindwing more curved towards tornus, both wings with almost uniform 
purplish-fuscous broad border from shortly after postmedian to termen. 
Warmberg, Transvaal, 22nd December, 1903. 
A worn $ in coll. British Museum is rather smaller (32 mm.), much less 
dark-suffused in terminal area above and beneath (though this is to some 
extent due to its condition), antenna with slender fasicles of cilia, hindtibia 
not dilated, “ Cape ” (W. H. Heale).
