Bruner: South American Crickets. 385 



ring in South American territory. However, if we may judge by the 

 numbers of species and the diversity of form and habits characterizing 

 the ants belonging to the neotropical fauna, we most assuredly have 

 a right to surmise that at least several additional species of Myrme- 

 cophila will ultimately be found in other portions of South America. 



Family MOGOPLISTID^. 



The representatives of the family of Mogoplistidae are all rather 

 small crickets, which have their bodies more or less clothed with 

 scales. These insects are widely spread over the warmer countries of 

 the globe. Already eleven genera are known and upwards of fifty 

 species. The group so far as North American territory is concerned 

 has comparatively recently been carefully studied by Messrs. James 

 A. G. Rehn and Morgan Hebard {see Proc. Acad. Nat. Sci. Philad., 

 1912, pp. 184-234, figs. 1-28). 



A single native specimen of the family is at hand. 



49. Crjrptoptilum antillarum (Redtenbacher). 



For a very full synon^^my of the species see Rehn and Hebard, /. c, 

 pp. 196-201, figs. 5-8. 



Habitat. — A 9 from Blue Hills, Nassau, Bahamas (W. W. Worthing- 

 ton). This insect was taken in January, 1909. 



In addition to the above recorded insect there is a very imperfect 

 nymph before me from "20 miles east of Bom Jesus da Lapa, Bahia, 

 Brazil" where it was taken December 8, 1907, by Haseman. It is 

 further marked by the Carnegie Museum Accession No. 3765. 



Family PENTACENTRID^. 



The small family Pentacentridse, so far as known, is represented in 

 America only by a single genus and one species, viz., Nemobiopsis 

 gundlachi Bolivar, from the island of Cuba. This family is char- 

 acterized as shown in the synopsis of families on a preceding page. 

 The material at hand for study does not contain representatives of 

 the group. 



Family PHALANGOPSITIDyE. 



This is an extensive family composed of numerous genera, the rep- 

 resentatives of which are distributed over the warmer countries of 

 the earth. A dozen or more of the genera have representatives in
