replaced by white ; the narrow white submarginal stripes broader 

 and more distinct; spots at anal angle smaller. Exp. GO mm. 



Hob. Treasury Island, Solomon Islands. 



Obs. Allied to C. kelia, Feld., but white band quite 

 straight on outer edge and much narrower, and barely 

 extending beyond costal nervure. It is altogether a 

 larger insect. 



Diadema fuliginescens, n. s. (PL IV., fig. 6). 



2 • Upper side deep fuliginons-black, inclining to fuscons 

 towards the outer margins. Fore wings : — A curved band of five 

 white spots beyond the middle extending from costa to third 

 median interspace, the spot between costa and costal nervule 

 divided by a nervule ; spot between discoidal nervules much the 

 largest and elongated ; indications of spots between first and 

 second median nervules and first median nervule and submedian 

 nervure ; three or four small white apical spots ; a submarginal 

 row of small white spots bordered outwardly by a narrow black 

 stripe, Hind wings : — Outer margin with a broad whitish band 

 clouded with sepia towards junction with discal area and at apex ; 

 a row of white spots through the centre between the nervules ; 

 nervules crossing bands and between spots well-defined and deep 

 pitchy-brown, outer margins the same, but narrowly and well- 

 defined ; fringes white, except at the apex of each nervule, where 

 ilir\ are dusky. Underside: — Markings much the same as on 

 upper side ; basal and central area dark sienna-brown, brighter in 

 cell. Fore wings : — Basal portion of costal area irroratcd with 

 minute bluish-white atoms ; three wdiite spots with black margins 

 in cell just below costal nervure, minute bluish-white atoms 

 between the two nearest the apex, and a blotch of the same below 

 the central one ; apex light brownish-ochreous ; a narrow dark 

 submarginal stripe bordered on each side by white, and a sub- 

 marginal row of somewhat indii tine! white spols, the one at anal 

 angle the largest and enclosed in dark sienna-brown, and with a 

 light bluish triangular spot above it. Hind wings : — The marginal 

 band considerably broader than on upper surface, and with a 

 distinct dark band running through its centre, in which the white 

 spots are more clearly visible. Exp. 78 mm. 



Huh. Qgi, Solomon Islands. 



Obs. Tliis species is allied to />. Forbesii, Butl., but 

 differs in the shape of the apical spots, the costa is
