Rhopulocera from Central Cerum. 105 



Ab. 1. — Uppei-side witli the grey areas almost buff-colour. 



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

 and curved postdiscal band 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 hasiflava. 



For ab. 1 we propose the name lutea. 



Eribcea Jupiter, ab. recdfascia, ab. no v. 



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 s[)ecies may ultimately form a race. 



(J ? . 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. 



3 c? c? , 1 ? , 2500-6000 feet. 



Besides the above a series of 12 J" c? of Jupiter were 

 obtained by the collectors. 



Ebibcea pyrbrus, Linn., and its Allied Forms, 



The discovery of the jupiter lorm on Ceram is of great 

 intere.-^t as previously only pi/rrhus, L., was known from there, 

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

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

 the revision of the Charaxes group by Rothschild and Jordan 

 in 18dS, jupiter, Butl., has been treated as a race of pi/rrhus, 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 torms ot the pi/rrhus group in this 

 new light, and our conclusion is that three species are rej)re- 

 sented. It must l;c said that at present no examination has 

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