DANAINAE. 



Danaida formosa, Godm. 



A nice series in fine condition. 



Same, Mabirioni. 9 (^<^, 3 ??. May 16-July 14. 



D. petlverana, Doubl. 

 Ufiomi (woodland). 1 (^. June 4. 



D. chrysippus, Linn. 



Forty examples, of which only three are typical chrij- 

 sippus. One approaches alcijjpoides, Moore, and three are 

 of the albinus, Lanz, form. The rest are all dorippus, 

 Klug.* The remarkable corresponding predominance of 

 the daira form of Acraea encedon in this collection is 

 referred to under that species. 



All dorippus unless otherwise stated. 



Kikuletwa, Darjama River (thorn-bush) — 1 $ Mar. 19; 

 Loldiloi (wooded river-side) — 11 (^t^, 1 ^ chrysippus, 1 ^ 



* In Seitz' " Macrolepidoptera," Professor Aurivillius separates 

 the dorippus form as a distinct species, with the remark that there 

 is not sufficient evidence of its specific identity with chrysippus ! 



Any good series, however, shows many remarkable i titer ntediates, 

 and specimens in the Hope Dejxtrtment bred by the late Col. Manders 

 show in a large number of specimens the instability of the fore-wing 

 apical black. There can be no doubt that dorippus is a form of 

 chrysijipus just as inaria is a form of misippus.
