Rhopulocerafrom Central Ceram. 405 



Ab. 1. — Upperside with the grey areas almost buff-colour. 



Ab. 2. — Hind wing below with a cloudy narrow, white, 

 and curved postdiscal baud touching the cell. 



Ab. 3. — Hind wing as in 2 but postdiscal band yellow, 

 and some scattered yellow scaling in the cell; extended 

 yellow scaling on the median area. 



Ab. 4. — Hind wing as in 3, but with sharply defined 

 yellowish-white band and dark basal area bearing scattered 

 yellow scales. 



Ab. 5. — Hind wing as in 4, but with dark yellow basal 

 area. 



The ab. 2 belongs to the typical form of <$ described by 

 Rothschild. 



For the form in which the postdiscal band is entirely absent 

 we propose the name cenus. •* 



For abs. 3 and 4 we propose the name mediofasciata. 



For ab. 5 we propose the name basiflava. 



For ab. 1 we propose the name lutea. 



JEribcea jupiter, ab. rectifascia, ab. nov. 



The series of this species collected in Central Ceram do not 

 differ from specimens found in New Guinea, but an interesting- 

 aberration seems to deserve a name, as it is possible that in 

 Ceram this species may ultimately form a race. 



$ ? . The discal band of the hind wing has lost most of 

 the glaucous edging, so that the distal border is straight, and 

 there is at most a few scattered blue scales beyond it.

Besides the above a series of 12 <J $ of jupiter were 

 obtained by the collectors. 



Ebibcea pybbeus, Linn., and its Allied Forms. 



The discovery of the jupiter form on Ceram is of great 

 interest as previously only pyrrlius, L., was known from there, 

 and is recorded by Rothschild (Nov. Zool. vol. xxii. p. 134, 

 1915) from Manusela at an elevation of 650 m. Ever since 

 the revision of the Charaxes group by Rothschild and Jordan 

 in 1898, jupiter, Butl., has been treated as a race of pyrrhus, L. 



We have now to consider these as being two distinct 

 species, and this view is further supported by the distribution. 



We have examined the forms of the pyrrhus group in this 

 new light, and our conclusion is that three species are repre- 

 sented. It must be said that at present no examination has 

 been made of the genitalia, and the position of a few of the
