it and cell some irregular black partly projecting into cell, wide 

 at costa, narrow at base of 3 and turning downwards to inner 

 margin to form a suffused inner edge to the hind-marginal 

 border. The latter greyish ochreoiis with black nervule ends 

 and dark ochreous elongate triangular internervular marks edged 

 with black. A fine black line round margin. Some irregular 

 blackish along basal half of nervure 1. 



H.-w. greenish grey at base with a black spot in 8, and some 

 black at base of nervures. Next to the basal grey two spots in 

 7 enclosing a red mark and a dot at base of 6. A spot on upper 

 discocellular joined to two in cell, the three enclosing a red 

 mark. A large spot in Ic, and a smaller one in lb and la. 

 (These spots are sometimes divided, and there may be an ad- 

 ditional spot in cell so that the spots form roughly a double row ; 

 and there is sometimes a basal spot in cell.) Central area pale 

 ochreous. Hind-marginal band shaped as above, its inner edge 

 marked by a brown line, the nervule ends black, edged with 

 pale ochreous, a fine black line round margin, on which are 

 subtriangular pale ochreous spots, each produced into a brown 

 ray and edged with black. 



Head black, with pale marks behind and between the eyes. 

 Brownish tufts on collar. Thorax black with a few pale marks. 

 Abdomen black above with pale yellowish lateral spots and 

 segmental lines. Claws unequal. 



$ . Expanse 56-60 mm. Except for its much greater expanse 

 of wing resembles the (^ . Often an elongate spot in middle of 

 cell. The h.-w. marginal border is much broader, and bears pale 

 ochreous marginal spots, together with more distinct indications 

 of the underside pattern. The basal and subbasal spots of 

 h.-w. underside are larger and separated so that the following 

 may be distinctly observed : — One at base in 9, one in 8, two in 

 7 enclosing a red mark, one on upper part of discocellulars, two 

 in cell enclosing a red mark, and a basal spot. A basal and two 

 subbasals in Ic, the latter enclosing a red mark, one in lb, and 

 two in la. 



A. eahira f. apecida. 



This form dift'eis in having the central areas of both wings, 

 and to some extent the f.-w. subapical patch, reddish yellow. 

 Nearly every intermediate shade of colour may be observed in a 

 long series. 



A. eahira f. ahrvpta. 



This form is described by Griinberg from Sesse I. in the 

 Y. Nyanza. It differs principally in the absence of striatior.a
