African S'pccics of the Gcmis Acram. 61 



A large ovate black spot in cell sliglitly beyond middle, a sub- 

 linear spot on l.d.c, sometimes extending to ii.d.c. A discal 

 row of two to three spots, (sometimes absent) beyond cell in 4, 

 5, and 6. A spot in 2 and another in 3 near cell, and a larger 

 spot in lb near middle. H.-w. brick red, blackish along costa 

 and creamy at inner margin. Black spots arranged as follows. 

 On margin, indistinct spots at end of nervules, a subniargiiial 

 row of seven spots parallel to margin, the first in Ic. A discal 

 row of eight, the first in lb, very small, and those in 2 and 3 

 much larger than the rest, seven or eight spots at or near base 

 five of which form a subbasal row, the first and second (in la 

 and lb) small or obsolete, the fourth in the cell, the fifth in 7. 

 Underside of f.-w. devoid of scales. H.-w. thinly scaled with 

 milky white, spots smaller than on upperside, many absent 

 altogether. Thorax black, spotted with reddish yellow beneath. 

 Abdomen black above, reddish or yellowish beneath and with 

 white lateral segmental spots. Claws unequal. 



$. Expanse 90 mm. Most exayiples resemble the $ but the 

 red areas are paler and duller. Rarely the red is absent in f.-w. 

 and replaced by creamy white in h.-w. 



IMabille figures (/. c.) a curious aberration of the ^ iu 

 which the spots are coalescent, forming curved and zigzag 

 lines. The figure in Ohenu's Encyc. of Nat. Hist, (un- 

 coloured) apparently shows a very dark hind-winged 

 aberration. Ward's figure, a ^, is near Mabille's fig. 3, 

 but has two black spots beyond cell in f.-w. which are 

 absent in Mabille's figure. 



This very distinct species is one of the largest of the 

 genus. It is described by Mabille as comparatively rare, 

 inhabiting wooded recfions in Eastern Madagascar, and 

 fiying with rapidity in the glades. The structure of tlie 

 ^ armature is quite distinctive.

* The position of this species is difficult to decide. I am inclined 

 to nuidify my original view and isolate it altogether.
