156 Mr. H. Eltringham's 3Ionogrciph of the 



present in the cotype and not in the type ; in 4 a spot near 



margin immediately beneath tliat in 6, a spot in 3 not quite 



touching end of cell, one in 2 touching median and nervule 2, 



a large transA^erse spot in Ic, nearer to margin, and one in lb 



and la nearer to base. In addition to these, a spot in 8 slightly 



removed from jirecostal, a subbasal in 7, two in cell, one at bane 



of 5 touching m.d.c, a transverse subbasal spot in Ic and la, 



and between these, but more distally placed, a small spot in lb. 



Head and thorax black, latter with a few brown hairs, 



abdomen black with the last two or three segments orange. 



Claws unequal. 



9 unknown. 



There are at present only two examples of this Acraea, 



the type in the National Collection and the cotype 



at Oxford. Both were taken by Neave on the Lualaba 



River, Belgian Congo. It is distinguishable from small 



examples of A. arrita by the f.-w. discal spots, and from 



acrita munca by tlie broad black apical patch. 



The genital armature is very distinct. The claspers are 

 entirely different from those of acrita, or indeed of any 

 other species I have examined. The true uncus is reduced 

 to a mere bristle, whilst the chitinous sheath of the penis 

 is developed into what appears to be a false uncus.
