162 THE entomologist's recobd. 



We will now consider the American species. One monotypic 

 genus, 2Iorsea, Scucld., is found in California, but the other groups, 

 Ejnsacti, Jutuiastaccs, are essentially Neotropical. A good number of 

 species are known, distributed through about half-a-dozen genera, but 

 all are confined to the Neotropical region, extending from Guatemala 

 to Paraguay. They appear to be most numerous in the neighbour- 

 hood of the Upper Amazons, in Peru and Ecuador. 



The last great group, the Therideis is again essentially Ethiopian. 

 About eight genera are knoAvn, all confined to tropical Africa, includ- 

 ing Sokotra and Madagascar. Except C'ljniatopsyijiiia JiaheUifcrum, 

 K., none are capable of flight, and many are totally apterous. Macvu- 

 mastax is found only in Madagascar, but the other Malagasy genera 

 are well represented on the mainland. The only other group repre- 

 sented in Africa is, as we have seen, the L'hoiveti/pi, and of that only 

 tAvo genera are peculiar to the region. 



To sum up, we find that (1) the Oriental region contains exclusively 

 the Erucii, it has also the Goinphoiiiaiitaces: straggling into the Palte- 

 arctic region, the Krlantld straggling into the Australian region, and 

 Choyoettjpi with two genera in the Ethiopian region. (2) The Neo- 

 tropical region has a monopoly of the Kinmcti and the Eiimastaces, 

 except one genus straggling into the Nearctic region, and no other 

 Eumaatacidae are found in the New World. (3) The Ethiopian region 

 has a monopoly of the Tlicrideiii, and also has two genera and one odd 

 species out of the typically Oriental group Clwrocttjpi. 



Myrmecophilous Orthoptera. 



By H. St. J. K. DONISTHOEPE, F.Z.S., F.E.S. 



According to Wasmann all the true myrmecophilous Orthoptera 

 belong to the Gri/lladca, though there may be some myrmecophilous 

 species in the Phancropteridae. Many species of Blattodca, such as 

 the North American TiDnwptcyijx dcyopehiforviii^, Brunner, are found in 

 the company of ants, but it is doubtful if they are truly myrmecophilous. 

 The following is a list of the species that frequent ants' nests. 



Myrmecophila acervorum, Panz., is found in the adult state (^s 

 and ? s) in middle Europe with Formica fiisca, F. sawininea, and F. 

 sang ti hie a with F. fa sea as slaves. It is also found Avith Lasius ni(/er, 

 L. alienu.'< and M>jr)inea laeviivnUs. The quite young larvfe have been 

 found with Tetrccmoriiini eaespltutii. In south Europe and north Africa 

 it has occurred with ApheiencMj aster testaceojnlosa, Cainpunotus lateredis 

 and C. dichroHS. A variety occurs in India with Botltropunera sulcata, 

 where also i\iQ\dJi. Jiaxveineta, Wasm., is found with PIa(/iolepis lowjlpes. 

 Mr. Burr calls attention to the fact {Fnt. Record, 1899, p. 187), that 

 Westwood recorded this insect from Netley, where it had been taken in 

 moss, but that further evidence is necessary to confirm it as British. 

 Myrmecophila ochracea, Fisch., is found in southern Europe and North 

 America with Aphacnojiaster harhara, and its very young larvte with 

 Pheidole jiallidida. Myrmecophila salomonis, Wasm., has been recorded 

 with Monomorinm, salomonis from Tunis. Myrmecophila pergandei, 

 Brun., occurs in Columbia in the adult state with Formica fusca var. 

 snhsericea, and also Avith F. integra, F. pallideftilra, Camponotus 

 mari/inatus and C. mclleus, and its larvfe at various stages with 

 Cremastofjastcr lineolata,&nd more seldom with Aphaenofjaster tenesseensis.
