for the characters of both mima and wahlbergi are represented 

 upon it. The other reason given is "that the two forms are 

 always found together wherever they are met with in any 

 number " {I.e., p. 491). This may be a fact, but it is also true 

 that they fly just as often with Pkmema esebricOy Planema 

 aganice, Amauris echeria, and Pcqnlio brasidas, E. tnima very 

 much resembling the latter when on the wing. I give below a 

 summary of the habits of these two forms so far as I have 

 observed them in Natal. It will be seen at a glance that they 

 are widely different. 



E. %oahlbergi. 



To be found from middle of 

 December and during January 

 and part of February.* 



Imago emerges from pupa 

 between 9.30 and 11.30 a.m. 



Always rests upon upper 

 surface of leaves or the ground 

 with wings folded except when 

 drying after emergence, when 

 they are continually opened 

 and shut like those of a Sat- 

 urnid moth. 



Flight slow and hovering, 

 and when disturbed the insect 

 usually returns after a time 

 to the same spot, often to the 

 same leaf. 



Vei^y much commoner than 

 E. Tnima : at least ten of wahl- 

 bergi may be seen to one of 

 mima. 



E. mima. 



To be found about first 

 week in January and during 

 February. 



Emerges between 2 and 4 

 p.m., never in the morning. 



Always rests upon the under- 

 side of the leaf with wings 

 shut and hanging down, except 

 when drying which usually 

 occurs upon the sand or very 

 low herbage. 



Flight very much quicker 

 than E. ivahlbergi, and if dis- 

 turbed or missed the butterfly 

 flies high and does not return 

 to the same place. 



One of the rare species here. 

 I should consider ten to twelve 

 a probable estimate of the num- 

 ber which might be seen in an 

 average season. 



I think there is sufficient difference in the habits set forth 

 above to indicate that we are dealing with distinct species, but 

 a few additional i-emarks may not be out of place. I have 



* Mr. Leigh writes on May 2G, 1906: — "I have seen two or three 

 E^iralia waJilhcrgi this month : last year I saw none after February and 

 early March. The specimens now seen are very much larger than the 

 earlier brood, but not so common." [E. B. P.]
