(7) After the i-efusal of the Melanitis and the Gegenes, 1 P. cebrene and 

 1 Pyrameis were eaten, each of these species and a C. hrutus being then refused. 



(8) Out of some of these placings it seems possible to extract the following 

 grades : —

2. A. phalantha, E. dryope, Sarangesa. J and R. pisistratus hereabouts. 



3. N. agatha, P. isokani, N. thalassina, N. goochi. 



4. M. yulei, T. senegalensis (this last not tested against N. goochi, than which 



it is at any rate appai'ently not higher).

The above gives a rough idea of the placing, relatively to I'epletion-point, of some 

 of the species used. In particular, it seems to show that M. yulei and T. senegalensis 

 are placed very low.] 



Exp. 28. — May 27. Refused most pei^sistently a Nychitona medusa, but ate 

 readily after crushing each an Atella phalantha and a Lampides bcetica. She then 

 accepted, crushed, and, after hesitation, swallowed a Terias, refused without tasting 

 a wingless Acrcea esebria, tasted and emphatically rejected Nyctemera leucono'e {yv\t\\ 

 tomato-leaf smell), and refused persistently without tasting a Mylothris agathina. 



She now ate readily two Charaxes brutus and after them, tasting each and then 

 swallowing it without the least hesitation, Neptis agatha and Eurytela hiarbas, 

 tasted and rejected a Belenois meseodina, but readily ate, after tasting it, a Leuce- 

 ronia thalassina. She then persistently refused a Terias and a Myc. campina 

 without tasting them, each with one wing, ate two more large Charaxes and a 

 Leuceronia argia and then with increasing slowness four more large Charaxes. The 

 next Charaxes was refused through sheer repletion, as also several other butterflies 

 including Pyrameis cardui. Precis cebrene, and Lampides bcetica. 



[Summary : — Charaxes spp. (and perhaps L. argia) were preferred to Terias 

 and M. campina, and, with L. thalassina, to B. mesentina, with C. brutus and
