Chcerotriche mirifica, n. sp. 



Primaries bright sulphur-yellow, covered with large dark- 

 orange spots, which upon the disk form an irregular oblique 

 series in which all the spots are of a quadrate form ; veins 

 and margins also orange ; two plumbaginous belts formed of 

 oval connected spots, one near the base, the other just beyond 

 the middle : secondaries bright ochreous, with the costal area 

 and apex broadly bright sulphur-yellow spotted with orange ; 

 an ill-defined orange belt from the abdominal margin to the 

 fourth median, where it (indistinctly) joins a large subapical 

 orange spot ; apical margin orange : thorax and base of abdo- 

 men deep reddish orange, almost red ; remainder of abdomen 

 ochreous. Under surface altogether of a more golden or saffron- 

 yellow tint, the orange spots less red, the plumbaginous belts 

 obsolete. Expanse of wings 3 inches. 



Old Calabar. 



This is by far the most beautiful species in the genus, if 

 not in the family. The genus Chcerotriche contains the fol- 

 lowing species known to me : — G, crocea^ Wlk. ; C. plana^ 

 Wlk. ; C. atomariaj Wlk. ; C.plagiata^ Wlk. ; C. Edwardsiiy 

 Newm. ; C. dersa^ Moore ; C. comjparata^ Wlk. ; G. disci- 

 nota, Moore. Also, probably, G. vitellina, Koll. ; G. varia, 

 Wlk. ; C. distincta, Feld. ; G. conspersa, Feld. ; G. glohi- 

 fera, Feld. 



Helicomitea, n. gen. 



Allied to Pterothysanus -, wings with similar neuration, but 

 broader, with different style of marking ; the basal half of the 

 wings covered more or less densely with upright hairs, some 

 of which are curiously thickened above the middle (like bul- 

 rushes) ; a radiating tuft of fine hairs at the base of the abdo- 

 minal margin ; abdominal fringe rather long, but not extending 

 quite to the anal angle : body much more robust than in 

 Pterothysanus. Type H. pulchra. 



Helicomitra p)ulchra, n. sp. 



Snowy white ; wings crossed by four series of annular black 

 markings, the third and fourth being near together on the 

 externo-discal area, the spots of the third series more or less 

 lunate ; a marginal series of partially black-edged ochreous 

 spots : primaries with the base black-spotted ; a black annulus 

 in the cell ; two large black costal patches ; the basal half of 

 costal margin vermilion-red ; three partially black-edged 

 vermilion costal spots between the cell and apex ; apical area 

 greyish : head black in front, with a white margin, white be-
