226 MESSRS. GODMAN AND SALVIN ON [Apr. 1, 



43. Tachyris SABA. 



Papilio saba, Fabr. Sp. Ins. ii. p. 46. 



A pair of this species, agreeing with our series of West-African 

 examples. 



44. Callidryas pyrkne. 



Colias pi/rene, Sw. Zool. 111. ser. 1, t. 51. 



Callidryas pyrene, Bull. Lep. Ex. t. 16. f. 8, 9, 10. 



Callidryas florella, Boisd. Sp. Gen. i. p. 608 (nee Fabr. apud 

 Butler). 



A single male specimen, which, according to Mr. Butler, should 

 bear this name. 



45. Teracolus evippe. 



Papilio evippe, Linn. Mus. Ulr. p. 239. 



Callosune evippe, Auriv. Kongl. Sv. Vet.-Ak. Handl. xix. No. 5, 

 p. 52. 



A male example. 



Papilionin.e. 



46. Papilio demoleus. 



Papilio demoleus, Linn. Mus Ulr. p. 214 ; Auriv. Kongl. Sv. Vet.- 

 Ak. Handl. xix. No. 5, p. 33. 



Several specimens of tbis common African species. 



47. Papilio pylades. 



Papilio pylades, Fabr. Ent. Syst. iii. p. 34 ; Donov. Nat. Rep. i. 

 t. 13 ; Trim. Ehop. Afr. Austr. p. 22. 



Forbes' s single specimen resembles Donovan's figure except that 

 the dark costal border of the primaries near the base is broader and 

 there is no red spot at the anal angle of the secondaries. The 

 species is a variable one, and we agree with Mr. Trimen that it 

 cannot be satisfactorily divided. 



48. Papilio merope. 



Papilio merope, Cr. Pap. Ex. t. 378. f. D, E ; Trim. Trans. Linn. 

 Soc. xxvi. p. 506 et seq. 



Papilio hippocoon, Fabr. Syst. Ent. iii. p. 38 ; Hew. Ex. Butt. 

 Pap. t. 12. f. 38. 



Forbes' s collection contains three specimens of this species, two 

 males and one female. The former agree with Sierra-Leone examples, 

 which should be considered the typical P. merope, Cr. The female 

 is like typical P. hippocoon, Fabr., from the same country. This 

 form of female has a wide range in Africa, extending to the Cape 

 Colony (Trimen) and in East Africa to Zanzibar.
