One male in not veiy good condition taken at Niangara about the 

 middle of November 1910. It agrees on the under side with a female 

 long in my possession, which was captured by the late Dr. A. C. Good 

 on the Ogove River thirty years ago. I once took this specimen with 

 me to London and it was examined by Miss Sharpe, who agreed with me 

 in my identification of it as her species latifinibriata. Aurivillius sinks 

 S. {Zeritis) fallax, cf , (Sharpe), as synonym of aderna Ploetz. I am quite 

 sure he is in error. Z. fallax Sharpe is bright blue on the upper side 

 of the wings, while S. aderna in the male sex resembles Axiocerses 

 yerion (harpax), as Ploetz, the author of the species, points out in his 

 description. The specimen before me accords with what Ploetz says 

 and might easily be mistaken by a novice for a specimen of A. harpax 

 upon casual inspection. Plcetz states in his paper that he had male 

 and female before him. The male of S. aderna on the upper side is 

 dark red and not blue, and Miss Sharpe's blue species is distinct, 

 in spite of the superficial resemblance of the insect on the under side 

 to that named bj^ Ploetz.

 d'. Frons reddish; a tuft of white hairs at the base of each antenna; antennae 

 black, short, with a moderately long spindle-shaped club, as in other species of the 

 genus; eyes dark brown, completely encircled with a ring of white scales; terminal 

 joint of palpi black, second and third joints heavily clothed with long vermilion 

 colored scales. Thorax and abdomen black above, deep orange-red inclining to 

 vermilion below. Legs with the femora and tibia; dark brown dorsally, pale red below, 

 at their point of union with the thorax surrounded by a ring of tuft-like white hairs, 

 which, is again encircled outwardly by a ring of long jet-black hairs. The fore wing 

 on the upper side is uniformly dark brown or sepia, except for a few dark orange-red 

 scales just before the hind angle, arranged to form a subtriangular spot, more or less 

 ill-defined. The hind wings above are of the same ground-color as the fore wings, 

 but about the middle of the discal area they are darker, being clothed with black 

 velvety scales. The entire inner margin is laved with deep orange-red, and this 

 color is extended over the whole posterior extremity of the wing, and along the outer 

 margin upward as a narrowing line to the extremity of vein 3. The dark brown cilia
