Congo. (Presented 1843, by Dr. Richardson ; collected by A. 



Curror, Esq., Surgeon, R.N.) B.M. 



"We have a beautiful local representative of P. Medon from the 

 Gaboon ; it chiefly diifers in having a central abbreviated green 

 band on the upper surface of the wings. 



6. Romaleosoma Eupalus. 



^ . Papilio (D. F.) Eupalus, Fabricius, " alis integerrimis fuscis, 

 posticis fascia caerulea, subtus viridibus, puncto atro: alae omnes 

 virides puncto baseos atro ; in quibusdam striga punctorum albi- 

 dorum : habitat in Africa sequinoctiali." $ . Euryphene Swan- 

 ziana, Butler, Proc. Zool. Soc. p. 222, pi. 17. figs. 7, 8 (1868). 



c? . Papilio (E. A.) Erithonius, Fabricius, " alis nigris ; posticis 

 fascia caerulea, subtus viridibus, striga punctorum alborum : habitat 

 in Africa." 



Fabricius, Sp. Ins. p. 54. n. 241 (1781) ; Mant. Ins. pp. 11, 

 27, n. 103, 279 (1787) ; Ent. Syst. iii. pp. 48, 82, n. 148, 

 255 (1793). 



This species seems to be quite distinct from Cramer's P. Harpalyce ; 

 both sexes agree in having no yellow band on the upperside, but a 

 series of white spots on the underside : it appears to be restricted 

 to the Ashti ancoast. The type specimen of P. Eupalus is in the 

 Banksian Collection. 



7. Romaleosoma Janassa. 



Papilio (N. P.) Janassia (sic), Fabricius [Janassa, var., Linnasus], 

 " alis repandis viridi aeneis : anticis punctis nigris, subtus flave- 

 scentibus punctis baseos nigris : habitat in Africa." 



Fabricius, Mant. Ins. p. 49. n. 487 (1787); Ent. Syst. iii. 

 p. 121. n. 371 (1793). 



Sierra Leone. (Collected 1858, by Mr. James Foxcroft) B.M. 



Fabricius, in his description of P. Janassa, makes no mention of 

 the subapical band upon the upper surface of the front wings; 

 we, however, have a specimen in which this band is somewhat 

 obscured by greenish scaling, showing a tendency towards the 

 obliteration of this character.
