oblique, fifth shifted inwards, sixth outwards; a submarginal row 

 of narrow internervular lunulcs, the upper two of which are shifted 

 well inwards and are diffused; a terminal rov/ of smallish half 

 spots; the black subanal spot with bright blue metallic scales with 

 a broad orange internal edging and a trace of a smaller one at the 

 anal angle. 



$. Upperside, both wings with the basal two-thirds to three- 

 quarters up to vein 6 whitish w^ith a strong suffusion of violet blue ; 

 costa and termen broadly brown, with a trace of whitish dashes 

 separating the submarginal brown border from the marginal border. 

 Underside like the male, except that in the primaries the postmedian 

 series consists of six spots.

Types in the Oxford Museum. 



This is a species that has given Professor Poulton and 

 me more trouble than any of the group, whether it was 

 negus Felder, or a paler tailless form of parsimon auctorem, 

 it was most difficult to determine, and we came to the con- 

 clusion that the latter was probably the best solution of 

 the difficulty; it proves, however, on examination of the 

 genitaha and the androconia to be without any doubt a 

 distinct species. 



Genitalia. Harpagines longish, ham-shaped at the base, tapering 

 into a moderately long arm-like organ, with a short, strongly 

 hooked apex well supplied with long strong bristles for all its length ; 

 anellus with the front edge curved ; aedoeagus of moderate length 

 and width; cingulum long, but of slight proportions; tegumen 

 raised into a very narrow ridge at the extreme rear; cheeks pro- 

 jected well forwards, of but moderate dimensions, with well-curved 

 front margins which are well supplied Avith long bristles ; falces very 

 long and curved highly near the base. 



Androconia variable, of two sizes ; one being of a long oblong shape 

 with the distal extremity very slightly curved, and the proximal taper- 

 ing rapidly off into the long footstalk, and the other much shorter, 

 almost cjuadrate; these latter are much the more numerous; the 

 sculpturing on both is the same, there being twelve rows of reticu- 

 lations, not very close to each other, with the reticulations far ajoart 

 vertically. There is one very interesting aberration which apjaeais 

 to be an ill-developed androconia ; it is most unusually large, and
