The red submarginal band on the underside of the posterior wings 

 very much wider than in either the East or West Coast forms.

Male. — Upperside. Both wings blackish brown, slightly tinged 

 with violet ; anterior wings paler towards the apex and crossed by a 

 broad purple band broader than in heivitsoni, Daum., from beyond 

 the middle of the costal margin to nearly the outer angle ; a minute 

 siibapical white spot. Posterior wings with a band of same colour 

 commencing on the costal margin at about two thirds of its length, 

 extending to the outer margin, thence gradually narrowing down 

 the outer portion of the wings to near the anal angle. 



Underside. Basal two thirds of both wings dark olivaceous brown, 

 the outer edge of which is sharply defined by a narrow pale vio- 

 laceous space. Anterior wings with the outer third violaceous brown 

 in which are three spots, two being subapical and small with a pale 

 iris, situate below the subcostal nervule and the first discoidal 

 nervure respectively, the third spot larger with a black iris and 

 situate between the middle and lowest median nervule ; a sub- 

 marginal sinuate brown line, becoming obsolete towards the posterior 

 angle. Posterior wings with the outer third browner than it is on 

 the anterior wings, with a violaceous space at the apex and a row of 

 seven spots each with a black iris, the first, fifth, sixth, and seventh 

 larger than the others, the fifth being the largest, the sixth and 

 seventh spots at the anal angle distinct, not contiguous like the anal 

 spots of heu'itsoni. Outside the spots is a sinuate dark brown band, 

 broader towards the anal angle, and on its inner edge curving round 

 the spots. 



Expanse 2| inches. 



Nearest to /. hrwitsoni, but with longer wings and more spots on 

 the underside. I have several specimens of a closely allied species 

 from Cameroons, not, I believe, hitherto described.
