balism, situation of the different forms in the nest, the nuptial 

 flight, the establishment of new colonies, the royal pair and other 

 reproductive forms, association with ants, termitophilous insects, 

 parasites, damage to forest products, preventatives, remedies 

 and immune woods. The paper contains reports upon a consid- 

 erable number of experiments of one kind and another. There 

 are also recorded many interesting original observations. Con- 

 cerning the relation of termites to ants the author says that while 

 ants and termites are commonly found inhabiting the same 

 log or stump, yet ants are the enemies most to be feared by term- 

 ites, as they will capture and carry away the members of a dis- 

 organized colony. Ordinarily the relations between termites 

 and ants seem to be neighborly and peaceful. If the termite 

 colony is opened up and disorganized, the ants at once take 

 advantage of the opportunity and carry away the termites which 

 offer but little resistance. Ants of several species may be at- 

 tracted to such a helpless colony from a distance. The soft 

 bodied soldiers are apparently not very effective in such an emer- 

 gency, although in the narrow channels of the colony, where 

 the powerful head with open mandibles is the only front pre- 

 sented to the marauding ants, they afford some protection to 

 the colony. 



Two species of carpenter ants (Camponotus pennsylvanicus, 

 Mayr and Cremastogaster lineolata Say) are the ants which more 

 commonly have been found associated with termites in eastern 

 U. S. The latter species, due to its small size and rapid move- 

 ments is a most formidable enemy. 



Ants greatly diminish the number of the colonizing individuals 

 at the time of the swarm, carrying them away as they are run- 

 ning about on the ground. Soldiers and workers guard the 

 breaches from which the sexed adults have emerged. 



Theobald (20), describes several new species of Myrmecophil- 

 ous aphides and gives some behavior notes. 



Turner (21) watched the mating activities of Lasius niger in 

 St. Louis on Sept. 17, 1913. The entire mating behavior except 

 the copulatory act was observed. In discussing these activities 

 he points out that they are not readily explainable upon the basis 

 of simple tropisms. He states that at this time he observed 

 Formica species, present at the mating activities of Lasius, to 

 be eating the Lassius males and sometimes the females also.
