- the Rhopalocera of the Dollman Collection. 245 
B.M. Type No. Bh. 063, 3, Mutema, Lukanga Valley, 
Kashitu, N.W. Rhodesia, 10 vii. 1918 (H. C. Dollman). 
Length of fore-wing 3:1 cm.—some specimens a good deal 
smaller. 
(b) A. welwitscht nivea, subsp. nov. 
(Plate V, fig. 8.) 
1 3 (B.M. Type No. Rh. 064) from Solwezi, August 1917 
H. C. Dollman, differs considerably from the preceding. 
The black basal area of fore-wing does not nearly reach 
vein 2; the spot on discocellulars is minute; the black 
costal mark beyond is narrow, and only reaches vein 5, 
being followed by a small separate spot in area 4; ground- 
colour and margins as in A. w. lutea. The hind marginal 
border of hind-wing is very broad, reaching nearly to edge 
of cell in areas 3 and 4 particularly, where it gives place 
to white, which extends in an almost rectangular patch from 
inner margin to vein 6, and in the cell nearly reaches the 
base of vein 7; basal black of hind-wing of normal extent ; 
remainder of areas 5, 6, 7 and 8 of normal salmon-pink 
coloration. 
T should have hesitated to add another name to the burden 
of this species on an examination of a single specimen, 
were it not that Dollman says that “it is common in wood- 
land parts of the Solwezi District and that all the speci- 
mens were similar to the one (the type) in his collection; 
of those caught there was little, if any, variation.”

“2 $3 taken 30 xii. 1917 at Solwezi, one actually in copula 
with a 2 diogenes, Suff., and the other in close attendance 
on the pair, seem to furnish conclusive evidence as to the 
specific identity of these two named forms. The analysis 
of the spots, particularly of the hind-wings, confirms this. 
In addition 3. 29; xu. 1917,* and 1-9, 1.1918, also: at 
Solwezi. Probably a woodland jspecies and not met with 
elsewhere.”’
