crushed and rejected a large grey isopod with almond smell, also an orange-coloured 

 centipede (Scolopendra morsitans), readily ate another B. severina, tasted and 

 rejected a Tipulid fly, refused to taste a frog-hopper and a Psammodes sp., then 

 again crushed and rejected the Tipulid and a Galerucella triloba. Ten minutes 

 later she tasted and rejected a Syrphid fly [Rhingia coeridescens), but readily ate a 

 large number of small gi-asshoppers. She now refused, then tasted slightly and 

 rejected a B. severina, crushed well and rejected a Diphrontis vethi, refused with- 

 out tasting a Himatismus fasciculosiis, readily ate an E. hiarbas and a Nevtis 

 sioynnertoni (both with wings), refused to accept a Locustid, Enyaliopsis petersi, 

 after having very cautiously tasted the abdomen, and readily accepted and ate a 

 B. angolanus with one wing. Belenois in neai'ly all experiments nowadays is 

 offered with all its wings attached. 



Later in the day I gave the roller grasshoppers till she accepted them with 

 disinclination. She then crushed and readily ate a $ j^. mmpjozts with one wing, 

 crushed well and rejected a P. angolanus with one wing and just took it, crushed 

 it slightly, and threw it away on my reoffering it with the wing removed, barely 

 tasted and tossed aside a P. lyoius with one wing, crushed and readily ate an 

 H. misipjnis S with one wing, crushed and rejected a G.florella and very readily 

 accepted and ate a P. natalensis f. She then tasted with disinclination and 

 rejected a P. dardanus $ f. hippocoon and an ant-lion, a wingless P. demodocics 

 and a C. cloanthe $ .
