TROTECTIVE SIMULATION. 



lOI 



In Africa several species of the Danaincr and Acnrina;, 

 two entirely different sub-families, with very marked 

 superficial likeness, are found flying in company or

W. Mcchimitis lysininiii, V. Hresin sf>., VI. Mrchnnitis nfsea, 



VII. Ci'i-tttinia mpljtliis. \'III. C. niuonia, 



in the same localities, the ground colours of the wings 

 together with the chocolate or black and white spots 

 making them very much alike ; and in some of the Danaimc 

 and Lyccpnida' and also between certain Acnriiio' and 

 NyvipJialitio' a similar portraiture is found. 



Many of the different genera and species of the 

 Acnmiue exhibit these mutually protective features to a 

 large extent. This sub-family is widely distributed over 

 the continent of Africa and possesses the repellent features 

 of the Danaiiuv : the resistent vitality of its members is very 

 high and they are strongly marked and easily recognized 

 insects. Most of them are of a fulvous colour, promi- 

 nently marked with lines and bands of dark brown and 

 chocolate, sometimes dashed with white, and many are 

 dotted with conspicuous dark coloured and black spots
