ACRAIDA.—ACRAA. 
figure 233, of the same plate, which Godart quotes as the other sex, differs but slightly 
from my figure 30. The very clumsy misshapen figure of Drury (his P. Umbra) is 
evidently intended for the insect of my figure 32, and though he does not indicate 
in the figure the black spots at the base of the wing, he describes them. 
There is not much to be learned from examining the underside of the Acrzeas, 
except that the basal spots are better seen. It differs but little from the other side. 
The base of the costal margin of the anterior wing of this species is always black, 
marked by a rufous or white spot. 
The position of the first branch of the sub-costal nervure of the anterior wing 
varies slightly. In some examples it rises exactly at the end of the cell, in others 
slightly beyond it, and in figure 32 is at a greater distance than in any of the others, 
so much so, that in other genera I should have considered it a specific distinction. 
Fig. 21, which is from Sierra Leone, scarcely differs from Felders’ figure of 
Vestalis. It has the incipient band at the inner margin of the anterior wing. 
Fig. 22, from Old Calabar, is a small edition of figure 26, from Congo. Whilst 
23 and 24 differ but little, except in size, from 27, which is certainly the male of 
Drury’s Umbra. The black discal spot of figure 25, though producing a marked 
peculiarity in its appearance, is left there by the interposition of a portion of the 
rufous band between it and the base of the wing. 
Figs. 28 and 30 will pair pretty well together ; the male is from Old Calabar, 
the female from Congo. 
Fig. 31 differs from the Linnean type and from Cramer’s figure in not possess- 
ing the two white spots, which mark the first, or a continuation of the band, as in 
the figure, to the inner margin of the anterior wing. 
Figs. 22, 28 and 32 are from Old Calabar. Figs. 21, 27 are from Sierra Leone. 
Figs. 25, 26, 29 and 30 are from Congo. Of the three other varieties I do not 
possess any precise locality. 
They are all from the Collection of W. C. Hewitson.
