20 IIK'ITISII ORTHOPTERA. 



Whether this insect is destined to become thoroughly 

 established in Britain is uncertain, and time alone will 

 show; but the tendency seems to be towards a con- 

 dition similar to that of the house-cricket and the 

 kitchen-cockroach. 



DISTRIBUTION.- -Finot says (' Faune de la France/ 

 " Orthoptera," p. 65) : " Cette espece, assez rare, habite 

 les parties les plus chaudes du littoral de la Provence, 

 pendant 1'ete et l'automne. Elle se tient sous les 

 pierres et les debris." In addition it is found in Sicily, 

 at Genoa and Pegli in Italy ; it is common in the 

 south and east of Spain ; and it also occurs commonly 

 in the Island of Madeira (Burr). In India and Ceylon 

 it is found also ; in fact it is cosmopolitan, being 

 practically a universally distributed species.
