Notes on the Rhopalocera of the Dollman Collection. 235 
B.M. Type No. Bh. 050, 3, Solwezi, N.W.R. 14 i. 1918. 
B.M. Type No. Rh. 051, 9, Solwezi, N.W.R. 1 iv. 1918. 
In addition there are 14 gg and 1499 in B.M. taken by 
Dollman in various localities in N.W. Rhodesia. 
The series shows a fairly large amount of variation. In 
one male the upper subapical and postcellular spots are 
united, as also are the lower ones, whilst the middle sub- 
apical spot is very large, but not quite united with either 
of the others; in several the twin-spots of hind-wing band 
are more or less united. In the females one specimen has 
two large yellow spots in the cell distally, but this would 
appear to be unusual, though many show a tendency to- 
wards additional yellow markings in this area, and just 
beyond end of cell, and also a tendency towards the union 
of the subapical and postcellular spots as in the male 
specimen referred to above. 
Dollman states that he has “carefully examined the 
type of P. mackinnoni benguellae, Roths.,” and that “it is 
quite different from this race.”

2. Mylothris riippellii Koch. 
Pieris riippellia Koch, Indo-Austr. Lep. Fauna, p. 88, 1865. 
This species, judging by the series in the Dollman Coll. 
and in the B.M., would appear to fall readily into several 
geographical races. 
(a) M. riippellit riippellii Koch. 
Described by Koch as having the basal suffusion of hind- 
wing of same colour as that of fore-wing. He only mentions 
the male, and gives “ Abyssinia” as locality. No Abys- 
sinian specimens in the B.M. agree with his definition. See 
below. 
(b) M. riippellit kikuyuensis Bart. 
Mylothris riippellit, 2-form kikuyuensis Bartel, Nov. Zool. 
xii, p. 150, 1905. 
This name is best applied to the form occurring through- 
out the greater part of Br. E. Africa, Uganda and the 
Kilimanjaro District, although first described by Bartel 
_from the female only. It is characterised in both sexes by 
the redness of the basal suffusion of fore-wing, which thus
