183 Mr. J. P. M. Weale on South African insects. 



in appearance and habits are the two creatures, that I 

 have frequently lost sight of the spider, or captured an 

 ant in mistake. 



The Salticus which imitates the Camponotas is larger 

 and hairy, like the ant. Both these ants are fond of 

 sweet secretions, and visit the glands of the Acacia, and 

 also various kinds of Homopterous insects, the Cremaio- 

 (jaster being particularly attentive to different species of 

 Akeres, and it was on a diseased orange tree that I first 

 noticed the friendly terms on which the spider lived Avith 

 the ants. A great many small flies and other insects fre- 

 quent trees thus diseased, and in such numbers that I 

 have little doubt they may seriously diminish the food of 

 the ants. 



The Orthoptera referred to in this paper have been 

 identified by Mr. J. Wood-Mason. An explanation of 

 the mimicry of ants by spiders has been suggested by 

 Mr. Meldola. (Sec Proc. Ent. Soc, April 3rd, 1878,
