Exp. 169. — April 25. Tried and rejected weevil 187, readily accepted and ate 

 Mylothris rtoeppelli, tried and rejected a Psammodes perfidus, also some gnats, and 

 refused a Belenois. 



[^Order : — 



1. Mylothris rueppelli. 



2. Weevil 187. 



Nothing definite can be deduced with regard to the remaining insects.] 



Exp. 170. — Ap>ril 27. Hungry. Tried and rejected two weevils (No. 187 and 146), 

 tasted and rejected No. 120, very readily ate ^eZejiois se^'erma, tasted and rejected a 

 house-fly and a hive-bee, also Alylahris oculata, readily ate Odynerus vidneratus, 

 tasted and rejected once more the house-fly and the hive-bee, and readily ate 

 $ Mylothris agathina, wings and all. 



[The order (allowing for the known relative position between the Belenois and 

 Mylothris) was : firstly, Belenois severina, Mylothris agathina ^ , and Odynerus 

 vidneratus ; and, secondly, weevils 187 and 146, 120, house-fly, hive-bee, and 

 Mylahris oculata.'\ 



Exp. 171. — September 20. Found eating grasshoppers hungrily. Tasted and 

 rejected a stalk-eyed fly [jDiopsis), readily ate Henotesia persjncua, refused the fly, 

 crushed and readily ate Byhlia ilithyia, refused the fly, eagerly ate P. angolanus, 

 again refused the fly, but ate with avidity 12 medium-sized grasshoppers and 

 another P. angolanus. I had nothing of a lower-grade nature to ofi:er. 



\_Henotesia p>e'>'spicua, Byhlia ilithyia, Papilio angolanus, and grasshoppers were 

 distinctly preferred to the Diopsis, and the number of grasshoppers and butterflies 

 eaten after its flrst refusal were considerable (16), showing appetite.] 



Exp. 172. — September 29. Hungry. Inspected and refused to touch Musca 

 domestica, readily accepted and ate a l^erias brigitta, tasted well and rejected a 

 large bluebottle (Calliphora), again readily ate a T. brigitta, tasted and rejected a 

 Miosca domestica, and refused without tasting a bluebottle, afterwards tasting well 

 and rejecting a fruit-fly. After a number of grasshoppers she tasted and at once 

 flung away an A. rahira, readily ate a P. angolanus and a N. agatha, and refused 

 to touch the A. rahira (all of them wings and all). 



[The pleasanter grasshoppers, Papilio angolanus and Neptis agatha were preferred 

 to the fruit-fly, and the latter (on manner) to Musca domestica and Calliphora. 

 A, rahira was placed below P. angolanus and N. agatha.^
