New or little-known forms of Acraea. 411

Acraea (acerata) vinidia, ft. ruandae, Griinberg, /.c., p. 516, 
pl 1d, £.6:(1911). 
This form is described as bearing the same relation to 
f. diavina as does f. tenella to the type. The description is 
as follows :— 
Upperside very like that of tenella. Pale markings straw-yellow 
with faint reddish-yellow suffusion. H.-w. with small indistinct. 
yellow marginal spots. Subapical band of f.-w. as large as in 
tenella, the pale mark before the end of cell separated from inner 
marginal spot. Discal spot in area 1b and 2 large and well defined, 
but somewhat smaller than in diavina. Underside also very like 
that of tenella. Discal spot of 1b and 2 smaller than above. Black 
basal and discal spots of h.-w. small, the red streaks scarcely 
indicated. Length of f.-w. 19 mm.
