It is with some hesitation that I describe and name this 

 curious species from females only, but I am quite unable to find 

 any male in my own or any other collection to which it could 

 belong. It would appear to have no close relationships, but the 

 discovery of the male would probably be of assistance on this point. 

 From the fact that the discal spots of the primary make a line at 

 right angles to the costa, it must according to Professor Auri- 

 villius' list be placed in the acrita group. 



ACILEA NOHARA CHAMBEZI, Sllbsp. 11. (Plate I. fig. 5, S .) 



I captured in the Chambezi valley and near Lake Young at the 

 end of October and beginning of November 1908 a small series of 

 what appears to be a new northern race of A. nohara Boiscl., 

 which in some particulars is an extreme form of the halali Marsh. 

 race of that species. 



It is much larger than halali Marsh., of a bright rose-colour, 

 and differing from it in the still further reduction of many of 

 the markings, especially of the dark outlines to the veins on 

 the apex and outer margin of the primaries. In the secondaries 

 on the contrary the black margin is rather heavier on the average 

 than in halali. 



In the secondaries also, the three spots in the discal row in 

 areas 1 b, 1 c and 2 form a straight line, thus distinguishing 

 chambezi from halali at a glance. 



In the presence of a discal spot in area 1 b of primary and in 

 area 3 of secondary, chambezi agrees with nohara and differs from 

 halali. 



Except for two obviously dwarf individuals the average length 

 of the primary is 27 mm., compared with about 25 mm. in nohara 

 and 23 in halali. 



The female differs only in the colour of the upperside of the 

 primaries, which is tinged with ochreous and lacks the bright 

 rose-red colour of the male. 



Described from twelve males and two females.
