no geographical peculiarity to account for this. The representative 

 of what is perhaps a third race of acrita is figured by Weymer, 

 Iris, Dresden, 1903, p. 225, pi. ii. f. 4, under the name acrita bella. 

 Prom the fact that the localities of pudorina Staud. and those of 

 the eastern race of this species appear to overlap, without 

 apparent gradations between them, it is possible that the former 

 should be treated as a distinct species. I have, however, not been 

 able to detect differences in the genitalia between this and the 

 typical form. A. chceribida Oberth., which is treated by Professor 

 Aurivillius as a form of acrita, is, as we shall see immediately, 

 a quite distinct species. 



Both races of acrita are on the wing throughout the year. They 

 frequent woodland and wooded hill-sides. They fly rather low, 

 but have an extremely steady and unusually straight flight for an 

 Acraia. If once startled they fly considerable distances in a 

 straight line, without deviating to right or left. 



AcrjEA LUALAB.&, sp. ii. (Plate I. fig. 4, J .) 



Fulvous orange with apex of primary and spots black. Allied to 

 acrita Hew. 



J . Upperside. — Primary fulvous orange, with a well-defined 

 black apex and the following black spots : — one in cell ; a disco- 

 cellular ; spots in areas 3 and 5 near internal margin of black apex ; 

 a large spot in 2 below extremity of cell ; a spot in 1 b near outer 

 margin, another in 1 b below cell near base. 



Secondary. Ground-colour as primary; a black basal patch and 

 the following black spots : — one in cell ; a discocellular ; a spot in 

 2 at junction of 1st submedian with median ; two spots below 

 costa and seven around end of cell, that in area 5 evanescent ; a 

 fenestrated black outer margin enclosing seven circular spots of 

 ground-colour. 



Underside. — Primary as upperside but without black apex. 



Secondary. Black basal area of upperside replaced by whitish 

 enclosing three basal spots, also one in cell near its base and one 

 each in 1 a and 1 b immediately below it ; there is further a small 

 spot between costa and precostal ; also the following reddish 

 streaks : one along base of costa, one passing longitudinally through 

 cell-end, and three others connecting the two rows of spots lying 

 in 1 a, 16, Yc. 



Fringe of primary dusky, of secondary dusky becoming grey at 

 anal angle and along inner margin ; palpi pale ochreous tipped 

 black ; thorax black ; abdomen : first three segments black, the 3rd 

 bearing an ochreous lateral spot, the remainder dull fulvous ; the 

 last segment covered with long hairs dorsally blackish, ventrally 

 ochreous. 



Length of primary 22 mm.
