African Species of the Genus Acraca. 75 



The species is recorded (Traus. Eut. Soc, p. ooO, 1902) as 

 having been untouched after death by ants which had 

 eaten every other specimen in a box except A. admatha. 

 Mr. Bennett's note (Dixey, Proc. Zool. Soc, p. 374, 189S) 

 describes the species in Sokotra as " mostly seen in the 

 liills, at an elevation of about 2,000 ft. Not hard to get, 

 the flight being slow and bold." Mr. Crawshay describes it 

 .•it Nairobi (Butler, Proc. Zool. Soc, p. 923, 1900) as " com- 

 mon and fond of perching on a violet-coloured ' Devil's 

 Bit '-like flower which grows on the plains." 



The male armature shows a certain amount of individual 

 variation, the length of claspers and uncus being somewhat 

 inconstant. In the subspecies seix there is a tendency for 

 the claspers to be shorter. Neohule is undoubtedly the 

 mainland ropiesentative of mahcla, from which it is rather 

 doubtfully separable. Curiously enough the $ armature 

 of the latter approaches more nearly the usually shorter 

 structure shown in oieohtde seis. 



23. ACRAEA ZAMBESINA. 



Acraea zambesina, Aurivillius, Arkiv. for Zool., 5, No. 5, 

 p. 123 (1908) ; Mendes, Broteria. Ser. Zool., ix, fas. iii, 

 p. 160, pi. 7, f. 1 (1910). 

 Portuguese E. Africa (Ziuubo on Zambesi R.). 



I have not had an opportunity of examining this 

 specimen and can therefore only give Prof. Aurivillius' 

 description of it. 



9 . Expanse 56 mm. Allied to ..4. neohvle, Doubl., but having 

 the f.-w. fully clothed with scales and so devoid of transparent 

 areas ; it also differs from neobule in that the white centred basal 

 spot of area Ic of the h.-w. underside is mucli smaller tlian in 

 Heahnle, and scarcely larger than the basal spot in la. 



F.-w. above dull reddish yellow with narrow border (only 

 1 m. broad), triangularly marked at the ends of nervules, the 

 nervules near margin more or less black. F.-w. with the 

 following black spots. One in middle of cell, two coalescent at 

 end of cell, and five discal spots (in lb, 3, 4, 5, and 6). The 

 basal spot in lb and the di.-^cal in 2 wanting in the present 

 example. Spots arranged quite as in neobule, but larger, and 

 somewhat as in the form sokotrana, Rebel. On the underside 

 the f.-w. is coloured and marked quite as above except that 

 it is more or less powdered with whitish yellow scales at the 

 margin. The h,-w, is almost exactly like that of ncobule but
