114 MR. G. T. BETHUNE-BAKER ON NEW [Feb. 18,- 



but not broken ; a similar, much broader, but less-defined sub- 

 terminal stripe from about vein 8 or 9 ; apical half of terminal 

 area suffused with brownish to the postmedial line, tornal half 

 suffused nearly to the subterminal line. Secondaries with a 

 similar brown postmedial stripe as in the primaries, but inter- 

 rupted above the vermilion patch ; subtei-minal line yellowish 

 brown to the vermilion patch ; a dark suffused shading precedes 

 the termen ; a largish patch of bright red (almost vermilion) from 

 above vein 3 into the lobe, with a black spot below vein 3, edged 

 above with a dash of brilliant metallic pale blue, a similar dash 

 extending to the lobe, a small black spot in the lobe ; three tails,, 

 that at the lobe being the shortest. 



Expanse 34 mm. 



Hah. Makala,, Congo Free State : March. 



Type in the Powell- Cotton collection. 



The measvirement of this species may not be normal ; it is in 

 poor condition and slightly shrivelled, the left secondary being 

 ro.uch smaller than the right. 



PowELLANA, gen. nov. 



Palpi with second segment scaled smoothly and somewhat 

 swollen, reaching well above the vertex ; third segment longish, 

 fine, smoothly scaled ; eyes smooth ; antennae tapering very 

 gradually into a very fine club.^ — Neuration. Primaries with 

 vein 2 a third from the angle, 3 from well before the angle,., 

 4 from the lower angle, 5 from above the middle of the disco- 

 cellulars, 6 from the upper angle, 7, 8, and 9 forked, 8 near apex,. 

 9 well beyond the middle, 10 and 11 stalked from a short stalk 

 from the cell. Secondaries with vein 2 from beyond the middle,. 

 3 and 4 from the lower angle, 5 from well above the middle,. 

 7 from a third before the angle. Wings ample. Primaries : 

 costa strongly but evenly arched ; termen evenly curved. Secon- 

 daries subtriangular ; termen evenly arched ; apex angled, anal 

 angle somewhat acvite. 



Type, Powellana cottotd B.-B. 



PoWELLANA COTTONI, sp. n. (Plate IX. fig. 13.) 



(5 . Both wings cobalt-blue. Primai'ies with apex broadly 

 black, extending slightly into the costa; termen very broadly 

 blackish, invading the blue in a slight inward curve, tapering 

 very little at the tornus. Secondaries with costa broadish black, 

 termen less broadly black, fold grey from vein 1. Fringes 

 whitish in both wings. — Under side. Both wings with broad 

 zebra-like stripes alternating sublustrous white and olive-brown 

 with fine linear subterminal lines ; termen finely brown. Primaries 

 with the final zebra stripe in the postmedial area met at right 

 angles below the apex by a horizontal stripe from the middle of 

 the costa, over which is a short similar dash ; a double curved 

 subterminal brown line, parallel with the termen, touches tho
