I have only caught one d of this species. Snellen correctly distinguishes 

 this as a separate species from the also tailless species Nacaduba Dane of de 

 NicEviLLE, a specimen of which de Niceville sent him for comparison. In 

 the article referred to above he describes the new species minutely. 



He description runs as follows: This butterfly is more powerfully built 

 than the two preceding species. The secondaries show no traces of a tail. 

 On the other hand their inner angle on the upperside is pretty strongly hirsute. 

 The c? is dark purple-blue like that of Ardates with a not very distinct thick 

 blackish brown grey fringe line, and a trace of a darker spot by the somewhat 

 pointed inner angle of the secondaries. The 9 has a greyish brown upperside 

 with a slightly blue powdered basal area of the wings : the dark spot near the 

 outer margin of cell 2 of the secondaries is more distinct than in the c?, their 

 inner angle blunter, but the hairs are long. The underside distinguishes Donina 

 clearly from the three preceding closely related species, as the colour is clay- 

 yellow, in the d slightly greyish, especially on the secondaries ; also in the c? 

 the base of the primaries is thickly powdered with black-grey. In front of the 

 spot upon the cross vein of the primaries, which, like the other markings, is 

 edged with greyish white, another fainter one can be seen in the middle cell, 

 the curved row of lunules is fairly straight, retains the same direction 

 to about vein i, and consists of pretty distinctly separated spots; along the 

 outer margin runs a double row of grey spots. On the secondaries the spots 

 are less clearly separated, the outer margin is marked by grey dots in the 

 cells, edged toward the base by lunules ; in cell 2 there is a round coal black 

 spot, which toward the base has a dark yellowochre lunule, and in the $ the 

 outer margin from vein 2 to the inner angle is edged with white, before the 

 fine black fringe line which is otherwise the same in both sexes ; at the inner 

 angle another small black spot. The fringe is blackish brown grey, in the d* 

 especially, above not differing much from the colour of the fringe Hne. Thorax, 

 abdomen and legs are covered with light grey hairs. Nora Felder, which also 

 has a clay yellow underside to the wings, is less powerfully built, and has a 

 long tail at the end of vein 2 of the secondaries, the inner angle of which 

 has not the same long hairs. Comparing it with a c? of Nacaduba Dana de 

 Nic, sent to Snellen by de Niceville, he found that the secondaries of Dana 

 are also tailless, the inner angle also hairy, but not rectangular, the blue of 

 the upperside lighter, duller and more greyish, as in the European L. Semiargus 

 v. Rolth. ; the fringe-line fine, distinct and black, and the fringe brownish. 

 The underside is brownish grey, the markings, especially the form of the
