and vein 6 and encloses 5 black spots (in 2 to 5 and the discal cell), and on the hindwing covers the base 
of the areas 2 to 5 and the apex of the discal cell, whilst at the forewing it has two deep indentations 
of the black ground-colour. The second transverse band of the forewing beneath is short and terminates at 
the base of vein 3 entirely separated from the other markings. The first, very irregular transverse band of 
the hindwing is interrupted in the areas 3 and 4, the aperture, however, is closed by the second transverse band 
being interrupted in area 6; the proximal submarginal line of the hindwing is very much widened and filled up 
with silvery white. Nigeria. 
S. iza Hew. (69 g) differs from all the other species by the marking beneath described in the review. 
Hewitson described the species according to a $ (alleged to be <$) and says that the upper surface is ,,brown 
with dark spots“. The markings beneath are ferruginous-brown. Gabun. 
S. crustaria Holl. (69 h) was described according to a ,,Wings above Morpho-hlue ; costal margin 
and apical third of forewing as well as the anal region of the hindwing black.“ The marking beneath seems to 
agree with that of iza and only to differ by the spots being bordered with a reddish grey. It is probably only 
a race of iza. A $ before me above entirely corresponds with the description of iza, but it has the silvery 
markings beneath broadly bordered with black; the hindwing beneath has 3 black submarginal lines. Ogowe 
and Congo District. 
Second Group of Species. 
Although the markings beneath are chiefly arranged as in the first group, it is peculiar to all the species 
of the second group that these markings never reach entirely the costal margin of the forewing. In the 
latter species the upper surface has a colouring quite different from the normal type of Spindasis. 
Review of the Species. 
A. Forewing above with a distinct, straight, black submarginal band separated from the margin by the lighter 
ground-colour. Both wings beneath with three submarginal lines, the most distal one of which is sometimes 
broken up into dots, whilst the two proximal ones may be united into one band. 
a. Ground-colour above light orange or ochreous-yellow with reduced transverse markings being blackish- 
brown on the forewing, yellowish-brown on the hindwing. S. bellatrix. 
[3. Wings above with a whitish-yellow or whitish ground-colour which, however, is for the greater part 
removed by the broad and strong black transverse bands or transverse spots and is often only more 
extensive in the middle and at the costal margin of the forewing. 
*. The second transverse band of the forewing beneath is not straight and more or less interrupted. 
S. nilus. 
S. Jcaduglii. 
**. The second transverse band is straight, coherent, and reaches vein 1. 8. subaurea. 
B. Forewing above at least at the costal margin, apex and distal margin black, without a special marginal 
band; otherwise violettish-blue or orange or only with an orange anal-marginal spot. Hindwing above 
for the greatest part orange or violettish-blue. Forewing beneath before the margin with two transverse 
rows of 6 or 7 dots each, the proximal ones of which are distinct and filled up with silver, whilst the distal 
ones are indistinct or entirely absent. 
a. Hindwing beneath with a dark, greyish-brown ground-colour being ferruginous-brown at the margin. 
Wings above extensively violettish-blue or orange (<$). 
1. $ hindwing above at the costal margin broad black. 8. aderna. 
2. $ hindwing at the costal margin not broad black. S. loxura. 
8. Both wings beneath light whitish-yellow with distinctly prominent ferruginous markings. Forewing 
above black with an orange anal-marginal spot which in the $ may sometimes be very small. 
S. leonina. 
S. bellatrix Btlr. is probably only a southern race of the palearctic species S. acamas Klug. (Vol. I, 
p. 279, t. 75 i). Wings above light ochreous, along the costal margin of the forewing as far as the median lighter 
and at the anal angle of the hindwing whitish; forewing with a transverse band at the end of the discal cell 
as far as vein 2, a transverse spot behind the cell, reaching the vein 4, and a third spot reaching vein 6; in 
addition a sub marginal band almost broken up into spots, ending behind at vein 2; these markings are dull 
brownish. Margin and fringes narrow blackish; hindwing above without any other markings but the dull 
diaphanous transverse bands of the under surface; anal region whitish. Under surface dull white with 
transverse bands filled up with light yellowish; the space between the two proximal submarginal lines is also 
filled up with yellow, whereby a distinct submarginal band is created; the most distal submarginal line is broken 
up into dots. Nubia near Suakin, and Somaliland.
