All-female Batches of Acraea encedon, L., bred in 

 the Lagos District. — Prof. Poulton also exhibited examples 

 from three of the all-female broods obtained by Mr. W. A. 

 Lamborn, viz. from Companies 2 and 3 and from Family 1 

 in the table printed below. These three sets were chosen 

 because they prove that the unisexual batches are not neces- 

 sarily associated with either of the forms of encedon in the 

 locality. Thus Family 1 was all lycia, Company 3 all encedon, 

 while Company 2 was as nearly as possible half and half 

 (23 to 24). The table clearly shows, in a condensed form, all 

 the results hitherto obtained in this species by Mr. Lamborn. 

 Out of the three families, one was all-female ; out of the seven 

 companies, three. Furthermore, the results obtained from 

 the two sets of wild larvae strongly suggest that both were, 

 in chief part, composed of the scattered individuals of an all- 

 female batch, intermixed, in the June-July series, with an 



[lv 

 earlier bisexual brood, in the December series with a later 



one. 



It is to be noted that the three all-female companies were 

 bred from eggs laid normally in the wild state, and the con-
