The forms of Leuceronia argia, F., in the Lagos 

 district of West Africa. — Mr. W. A. Lamborn supple- 

 mented his previous account of two families of bred L. aryia 

 by referring to a short series of females taken at Oni between 

 April 1st, 1910, and January 25th, 1911, a period including 

 a whole wet seaxm and a part of two dry seasons. 



Of the series, seven were captured in the wet season and 

 three in the dry ; but the orange flush, sometimes found at 

 the base of the hindwing, was not due to climatic influence, 

 as was demonstrated by the following table : — 



April 1, 1910. Dry season. 1 female, yellcw, with orange 



flush. 

 May 31 ,, Wet Season. 1 female, yellow, without orange 



Hush.
