ANTS AND MYRMECOPHILS 403 



by him is as follows: honey-bees, flies, ants, pear thrips, and 

 apple aphids. 



Mann (14) here gives some ecological data that is of value. 

 In the main the paper is concerned with the description of a new 

 species that is, according to the author, an addition to the species 

 that occur at isolated points on the north coast as relicts of the 

 ancient coastal plain fauna. 



This paper by Mann (15) is largely a description and listing 

 of other insects that the author has found in the nests of ants in 

 Hayti. There are however occasional notes concerning the 

 behavior of the ants and their guests. He records the following 

 families of insects as occurring as guests in the nests of ants: 

 Gryllidae, Cercopidae, Membracidae, Lathridiidae, Bethylidae, 

 Syrphidae. 



Morrill (16) in working on remedies for the suppression of the 

 damage of the harvester ant in Arizona, reports that he has found 

 that Carbondisulphide cannot be forced into the galleries of the 

 ants even with a high pressure pump. He found that London 

 purple kills the ants readily and with little expense attached to 

 the treatment of the soil . He states that $1.17 worth of the poison 

 killed the ants in ten acres of ground where the nests of the ants 

 were estimated to occupy one and one fourth acres. 



In this paper Morrill (17) reports that carbondisulphide can 

 be used successfully in combating the harvester ant in Arizona 

 if the liquid is introduced into the nest and the hill then covered 

 with a galvanized tub. 



Smith (18) states that termites are damaging the lemon trees 

 in the vicinity of Germantown, California. 



In this account by Snyder (19) we have a very important and 

 valuable addition to our knowledge of the biology of our North 

 American termites. The account is based largely upon investi- 

 gations carried on in 1910 and 1911 as to the character and extent 

 of damage done to telephone and telegraph poles, mine props, 

 etc., by wood boring insects. The investigation showed termites 

 to rank among the most destructive agencies attacking crude 

 and finished forest products. The species that he has consid- 

 ered are distributed widely over the United States. 



The booklet is divided into a number of sub heads as follows: 

 Classification, history, biological experiments, communal or- 

 ganization, polymorphism (different castes), life cycle, canni-
