42 THE ESSEX FIELD CLUB. Prof. Meldola said that he was also most particularly interested in the examples of protection among galls referred to by the author. He suggested that the term "protective resemblance" would be more appropriate than mimicry in such cases. The instance of a gall protecting itself by a secre- tion which was attractive to ants was one of the most interesting cases he had heard of of late years. The protection was indirect; the ants protecting the gall because of the food which they found on it. This was quite parallel to the case published many years ago by the late Thomas Belt in his well- known Naturalist in Nicaragua. That distinguished observer had dis- covered that certain acacias were provided with hollow-thorns which secreted a juice palatable to ants, these insects finding both food and shelter within the thorns. By means of these standing armies of ants the shrubs were most effectively protected from other insect marauders which were immediately attacked if they alighted on the shrubs. It was a case of symbiotic association in which both insect and plant benefitted by the association and the same was doubtless true in the case of the gall mentioned by Mr. Lewis. Mr. John Spiller, F.C.S., commented in a laudatory way on the beauty of the drawings shown by Mr. Lewis. Votes of thanks were passed to the authors of the papers, and the meet- ing concluded.
