New or little-known African Butterflies. i 
DESMOLYCANA, gen. n. 
Allied to the genera Lycexnesthes, Hypolycena, and Zeritis. 
d Head small: eyes smooth ; palpi long, porrect, not rising more 
than half-way to vertex, the second joint decidedly long, flattened 
laterally, and inferiorly densely clothed with elongate erect scales, 
and the terminal joint very short, slender, cylindrical, rather blunt, 
clothed with closely-appressed scales ; antennz long (almost three- 
fifths as long as costa of forewing), rather slender, but with very 
well-developed, elongate, cylindrical, blunt club. Thorax rather 
slender. Forewings rather elongate, with somewhat acute apex ; 
hindmargin incurved a little above posterior angle, costa and inner 
margin nearly straight ; costal nervure ending about middle of costa ; 
subcostal nervure 4-branched—the 1st nervule originating a long 
way and the 2nd a moderate distance before extremity of discoidal 
cell,—the 3rd (very short) originating considerably nearer to apex 
than to extremity of cell, and the 4th running to apex itself; upper 
radial united to subcostal nervure a little beyond extremity of cell, 
lower radial originating rather nearer to subcostal than to median 
nervure. Hindwings slightly lobate at anal angle, and bearing a 
rather long moderately-slender tail at extremity of submedian 
nervure :; costa beyond basal prominence very slightly curved ; costal 
nervure extending to apex ; subcostal nervules originating a little 
before extremity of discoidal cell. Legs rather short, moderately 
stout ; tarsi of first pair rather long, with inferior bristles well 
developed. 
Type: Desmolycena mazoensis, sp. 0. 
I am unable satisfactorily to assign the Lycznide above 
characterised to any recognised genus, and therefore pro- 
pose a new one for it, although hesitating to do so in the 
absence of any specimen of the female. In neuration this 
butterfly is in agreement with the genus Lycwnesthes, but 
is of far more slender structure throughout: it has porrect 
palpi with short and blunt (instead of long and acuminate) 
terminal joint; longer antennze with cylindrical and blunt 
(instead of flattened and acuminate) club; a single longish 
sublinear tail on the hindwings instead of 3 slender 
pencils of short hairs; and an underside pattern and 
colouring altogether different from that of Lycwnesthes. 
From Hypolycena the new form differs markedly in palpi,
