groups of Arthropods mentioned in the body of the work. From this 

 table we learn that the entire number of myrmecophilous insects recorded 

 from the globe, and including several which, while not actually known to 

 have this habit, are placed here on account of structural peculiarities 

 which indicate as much, reaches 1177. Of these 993 are Coleoptera, the 

 best represented families counting up as follows : Staphylinidae, 263; 

 Paussidae, 169; Histeridae, 128; Pselaphidae, 113; Clavigeridae, 89. Thirty 

 families of beetles are mentioned as more or less certainly myrmecophi- 

 lous, and several of them contain from 15 to 40 species, each of which 

 live with ants. The Strepsiptera, which American writers have usually 

 treated as Coleoptera, furnish one species taken from the hind-body on a 

 Ceylonese ant. 



The Hymenoptera furnish 38 myrmecophiles, of which 22 are ants, and 

 14 belong to the parasitic families Bracomdce, Chalcididae and Proctotru- 

 pidae. The Lepidoptera have 26 members here, the Diptera 18, the Or- 

 thoptera 7, the Pseudoneuroptera i, the Rhynchota 72, the Thysanura 20. 

 Myriapoda are considered doubtfully included, or more likely simply ac- 

 cidental or inimical visitors. There are 26 spiders and 34 Acarina. The 

 Crustacea (Isopoda) have 9 representatives. 



The termitophiles are much less numerous, reaching the number of 

 105, divided thus : Coleoptera, 87 (of which 5 are Carabidae, 59 Staphyl- 

 inidae, 5 Pselaphidte, i Silphid, i Lathridiid, 7 Histeridae, 6 Scarabaeidas, 

 the Curculionidae and Chrysomelidae being doubtful), Hymenoptera 6, 

 Lepidoptera 2, Diptera 2 (doubtful), Orthoptera doubtful, Pseudoneurop- 

 tera 4, Rhynchota 3, Thysanura i. The Arachnoidea have four species. 



After this tabulated statement comes a bibliography of the subject num- 

 bering over 500 titles of greater or less importance, interspersed with 

 critical notes on their value. Next follows the catalogue proper, a list of 

 species classified first into families which are then divided into myrme- 

 cophilous or termitophilous species. In each case a reference or note 

 shows whence the information is derived, and where other attention is 

 needed it is given. A supplement of 19 pages contains descriptions of 

 new species, among them a number of North American forms. The 

 whole is well indexed and forms a work which will forever reflect credit 

 on its author and must form an essential part of the library of the student 

 of this fascinating branch of Entomology. H. F. WICKHAM.
