them. The male was much too fright- 

 ened to eat them in spite of the example 

 of the female. I then gave a L'. scverina 

 to the female and a B. mcsentina to the 

 male, both being eaten readily. The 

 female made a grab at my box, seized a 

 Mylothris agathina and a B. mcsentina 

 together and began eating them at the 

 same time; she soon found something 

 was wrong and dropped them, then picked 

 up the Mylothris, tasted it and threw it 

 away, eating the Bdcnois afterwards. 

 The male, who had meantime eaten an- 

 other B. mescntina, picked up the dis- 

 carded Myhitlifis, but on tasting it also 

 at once rejected it. Then four Tera- 

 colus omphalc and three T. acJiine were 

 eaten with undoubted appreciation by 

 both baboons. On giving each a H. 

 eripliia they were both tasted and re- 

 jected ; the female ate a T. 'phlegyas and 

 neglected another H. crijiliia. 



There can be little doubt as to the 

 distastefulness of this latter insect to a 

 certain extent, but I should be inclined ' 

 to rank it rather lower than Jlfyhfhris 

 and about on a par witli JVcptis afjatha. 



Finally, six Terias scncyalcnsis were 

 eaten without any sign of distaste by 

 both baboons, tiiough the insects are tco 

 small to be much appreciated by them. 

 Salisbury, Sc2}t. 21, 1900. — I could not yet say what 

 protective character is possessed by the Ichncumonidx, 

 but with the Bracons there can be no doubt that it con- 

 sists in their having a very strong and unpleasant smell, 

 somewhat resembling that of the Coccindlidiv, only rather 

 more pungent. They do not attempt t^ defend them- 

 selves by stinging, and their flight is slow, rendering them 

 very conspicuous on the wing. I gave one of the common 

 red species to my monkey {Ccrevpitliccus j7y^('r///Ar«s) the 

 other day. He put it straight into his mouth without 

 smelling it, but soon spat it out again. I then offered 

 the mangled remains to one of the baboons, but she merely 

 smelt and rejected them. Tt is interesting to note that
