310 RHOPALOCERA AFRICA AUSTRALIS. 



two pale indistinct lines, hind-marginal and sub-marginal ; 

 a wavy streak of fuscous-ochreous reaches inner-margin, 

 leaving anal angle white ; between apical and central 

 vitreous some ill-defined, elongate, blackish marks ; con- 

 tinuous of transverse line of apical vitreous, three or four 

 blackish spots. Hind-wing : basal fuscous-ochreous as in 

 fore-wing ; first sub-vitreous band of fore-wing continued 

 to sub-median nervure or inner-margin ; outer band irregular, 

 narrow, merged with inner on costa, and only reaching third 

 median nervule ; cell closed by a fuscous-ochreous streak, 

 succeeded by a transverse macular row of the same hue 

 quite across wing to inner-margin, where it much widens and 

 is sometimes joined to an outer, parallel, incomplete, 

 ochreous shade ; inner-marginal region fringed with long 

 hairs, densely so in $ ; a hind-marginal fuscous-ochreous 

 bounding line. UNDER-SIDE. White purer : basal colouring 

 wholly absent. Fore-wing : apical colouring very much 

 paler, not varied with dark spots. Hind-wing : vitreous 

 markings indistinct ; ochreous stripes almost obsolete, but a 

 conspicuous black spot, in fold of inner-margin near anal 

 angle, marking termination of outer one. Cilia broad and 

 white in hind-wing; narrow and brown-and- white in fore- 

 wing. 



The inner-margin of fore-wing is not so deeply excised in this species as 

 in C. Pillaana, Walgr., nor are the angles of hind-wing quite so pro- 

 minent. Four specimens (two of each sex) before me present no noticeable 

 variation of marking. 



We owe the discovery of this fairy-like species to Mr. Bowker, who 

 notes it as rare, and writes as follows regarding its flight : " A curioui 

 flyer, rapidly opening and shutting the wings (like a bird), with a sharp 

 creaking or buzzing noise. When at rest, keeps its upper wings nearly 

 erect, while the lower are expanded."

IMAGO. Head not so wide as thorax : palpi rather short, 

 the terminal joint short and but little projecting beyond 

 hairs and scales of second joint ; antenna rather long, the 

 club rather gradually thickened, angulated (not hooked), and 

 tapering to a point. Fore-wings with costa moderately
