New Butterflies and a Moth from Biak. 189 



$. Upperside with well-defined white band and darker ground- 

 colour than in rebeli. Discal spots smaller and first submarginal 

 line is less undulate. Hindwing with white costal patch suffused 

 by dark scaling between the two discal lines which are distinct. 



Underside paler than in rebeli $ and without any reddish tint. 

 Forewing with the discal dot in 5 and the one below vein 2 obsolete. 

 Hindwing with the pale discal band much lighter, eye-spots smaller, 

 and submarginal lines closer together. 



One $ shows the white band darkened distally. 



Length of forewing : (J 47 mm., ^ 43 mm. 



A series. 



19. Cirrochroa imperatrix, Sm. $. 

 Nov. Zool. 1, p. 348, c^. 



Similar to the <J, basal blue not so bright. Underside paler at 

 base, discal blue line a little wider as is also the proximal blue 

 bordering of the submarginal brown band. 



Length of forewing : 40 mm. 



A small series from Biak, June 1914. 



20. Cethosia chrysippe schoutensis, subsp. nov. 



(Plate XXVII, figs. 1, ^, 2, $.) 



Nearest to lucina, Fruh., from Jobi. Outer margin of 

 wings less strongly undulate than in other chrysippe 

 forms. 



(J. Upperside shot with deep blue except at margins. The white 

 subapical patch extends from subcostal 4 to vein 2, is rounded on 

 its outer edge, and is 9 mm. broad between veins 4 and 6. A short 

 subcostal streak before the band. The red at base of cellule 2 is 

 more reduced than in allied forms. Submarginal white dots are 

 only faintly indicated and this in a very few specimens. There is 

 a tendency to develop a dot in 2 on forewing and to reduction in 

 size of spot in 2. 



Underside darker than in damasippe, Feld. The submarginal 

 spots on hindwing larger and somewhat produced proximally. A 

 reddish suffusion between the discal bands and distally of the outer 

 band, the red spot at end of cell brighter. 



$ differs as in the allied forms. 



A series.
