To p. 33, after H e t e r o r a c h i s j u s c o t e r m i n a t a : 
H. platti Janse is near juscoterminata, but has the hindwing slightly concave between the radials, is 
rather broad-wdnged, much brighter than that species, including its stronger terminal line and more sharply 
chequered fringes; costal edge of forewing browm (in juscoterviinoAa whitish); vertex in front and shaft of an¬ 
tenna cream-coloxir, not red-brown as in despoliata. Only known from a Durban bred by Mr. E. E. Platt 
from larvae found on Canthmm obovatum. 
After I u n a t i m a r g o : 
H. conradti sp. n. Expanse 21 mm. Similar in shape to lunatimargo (4 b), but rather narrower-winged and 
nuich smaller. Palpus more minute (about as in idmo7i), tongue relatively strong. Antennal pectinations 2 
to 3 times diameter of shaft. Hindtibia, as in hmatimargo, with strong hair-pencil. Further agrees with that 
species in that the 1st subcostal of the forewing is stalked with the others, anastomosing with the costal (in 
the ty])e also with the 2nd siibcostal); 1st median connate (type) or very shortly stalked (paratype). Hind¬ 
wing with 1st median stalked. Coloration as in the two species named, the brown, dark-sprinkled borders se]ja- 
rated from the ground-colour by a creimlate dark line; breadth of border on forewing anteriorly 2 mm, be¬ 
tween 3rd radial and 1st median 1 mm, posteriorly widening to 2,5 mm; on hindwing similar, but with the larger 
expansion apical. N. Cameroons; Johann-Albrechts-Hohe (L. Conradt), type in Brit. Mus., paratype in Zool. 
Mus. Berlin. A $ from Cameroons, Bang Manenguba dist., 700 m, August 1910 (S. G. Schafer, Mus. Berk), 
agreeing in structure, is rather larger, slightly broader-winged, the borders less broad; antenna simple, a further 
indication that — like lunatimargo — this is not a true Heterorachis. 
To p. 34, after G el i d o m p h a x r u b > i m a c u I a t a : 
C. quadriplaga Janse is intermediate between ruhrmiactdata (4 b) and. aiialiplaga in that the terminal 
macidation is reduced, but not so completely as in analipJaga. Forewing with a vinaceous-fawn, proximally some¬ 
what black-mixed spot at tornus (its diameter scarcely 2 mm) and a very small and ill-developed cell-spot. 
HindAving with the spot at tornus consideral)ly smaller still and with a small streak on middle third of abdominal 
margin. Founded on a single cj from Umkomaas, Natal, measuring 38 mm. The genitalia sIioav some appre¬ 
ciable differences when compared with ruhrimaculata: socii larger and stouter; sacculus more rounded, and prov¬ 
ided wdth more teeth. Otherwise I shoidd have supposed it an extreme aberration of nibrimaculata, as I have 
an intermediate from Durban. 
C.analiplaga Warr. (18a). Thetype, which we shall figure, is a $ from Massasi, Tanganyika Territory, with 
the oblique red-brown blotch at the anal angle of the forewing reaching the 2nd median vein and a feAV red 
scales on the fold near the angle representing a corresponding spot on the hindwing. — ab. aplaga 7iov. (= anali- 
plaga Ja7ise) is the form with these anal spots entirely wanting. I have chosen as its type a second example 
from Massasi. Janse implies that this is the only form known from Sawmills, S. Rhodesia; from ShamA^a, 
hoAvever, I have the name-typical form. 
After 0. V i c i 71 i t a r i a : 
0. trilobata Janse. Expanse 29 mm. Similar to vicinitaria, as proAusionally determined, but Avith 
narroAver AA'ings, both the distal margins straighter, pectinations (outer series) less short, the longest exceeding 
tAA'ice the diameter of the shaft (in vicinitaria 1) and with different genitalia. Both species are described as 
deep glaucous green and virtually Avithout markings, but trilobata sIioaar indications of dark cell-spots. Durljan, 
a ^ bred from Tragia durbane7isis. 
After 0. n i g r i c 0 r n i s : 
0. particeps Prout. Like rubriceps (4 c), but AAdtli the croAvn and antennal shaft Avhite, the A\'hitish 
abdomen AA'ithout a trace of cinnamon or reddish crests, termen Avithout the dark dots AA'hich are often deA-e- 
loped in ruh'iceps; fringe white, at base slightly encroached u])on by the green colour, in distal half flushed 
AA'ith pinkish. Belgian Congo (type) and N. Nigeria. Distinguished from leucocraspeda l)y its more robust binld, 
more strigiilated A\dngs, pink-tipped fringes and shorter, stoixter pectinations. 
To p. 35, P. c a I I i s t a : 
deuterurga Prout, Avhich Avas published as a separate species, is shoAvn by Janse's studies of the geni¬ 
talia to be merely an aberration of callisia (4 c), ])erhaps even a synonym if the apparent differences are due 
to the condition of the individual examples.
