1867. J MR. A. G. BUTLER ON THE GENUS MYCALESIS. 719 



the synonymy of this extensive group of Butterflies has been use- 

 lessly increased. 



As, by a careful comparison of the types and typical descriptions 

 with the specimens in our collection, I have succeeded in satis- 

 factorily determining several of the above species, I hasten to lay the 

 result of my investigations before the Society. 



Sp. 1. Mycalesis melusina. 



Papilio melusina, Fabvicius, Ent. Syst. iii. pt. 1. p. 240. n. 7oO 

 (179.3). 



Hab. Sierra Leone. B.M. 



This has been already placed with P. dorothea of Cramer, with 

 which it is doubtless identical : it in almost every point agrees with 

 the insect from Old Calabar, described by Mr. Hewitson under the 

 name of M. raesaces. I have pointed this out to Mr. Hewitson ; 

 and he agrees with me that his species can be nothing more than 

 the Calabar form of the insect from Sierra Leone. 



1*. Mycalesis miriam. 



Papilio miriam, Fabricius, Ent. Syst. iii. pt. 1. p. 242. n. 7r)4 

 (1793). 



Hab. Angola. B.M. 



" Alis dentatis fuscis siibtus cinereis : anticis ocellis duobus, j)OS- 

 ticis septem. Habitat in Indiis.'^ — Ent. Syst. 



This only differs from the preceding in being entirely brown on 

 the upperside, and in having the markings of the underside mucli 

 more distinctly visible. 



Sp. 2. Mycalesis perseus. (Fig. 2, p. 718.) 



* Papilio 2>erseus, Fabricius, Syst. Ent. p. 488. u. 199 (1775). 

 Papilio tabitha, Fabr. Ent. Syst. iii. pt. 1. p. 243. n. 756 (1 793). 

 Hab. North India. B.M. 



" Alee anticce fuscce, mox ifnmacidatcB, mox ocello parvo, pupilla 

 alba ante apicem. Posticce fuscce, itnmaculatce. Subtus omnes 

 basi fuscce, apice dilutiores, anticis punctis tribus, j)osticis 

 septem albis subocellaribus.'" — Syst. Ent. 

 " AlcB supra omnes nigrce anticis ocello parvo atro, pupilla alba. 

 Subtus pallidiores striga e punctis ocellaribus minutissimis pu- 

 pilla alba." — Ent. Syst. 

 This is of course only another of the many varieties of M. otrea 

 of Cramer : the underside of the wings is represented by Donovan in 

 his ' Insects of Asia ;' but the colouring is so extravagant that the 

 figure rather hinders than aids the determination of the species. 



2". Mycalesis clerimon. 



Papilio clerimon, Fabricius, Ent. Svst. iii. pt. 1. p. 217. n. 678 

 (1793). 



Hab. ? 



* The type is in the Banksian collection.
