Gen. Cyrtotriii Stäl [= Stciiopilema Sauss.] 



Dr. Sjöstedt lias kindly sent to me for examination a number of Stäl's types 

 of Blattid^e. Amongst these are the male and female types of Cyrtotria gibbicollis 

 Stäl and they prove to be congeneric with the species included by de Saussure and 

 Zehntner (Rev. Suisse Zool. III, p. 25 (1895) in the genus Stenopüema. In the 

 genus Cyrtotria the distinguished Svviss orthopterists place Derocalymma clispar Burm. 

 Cyrtotria macra Stäl and with some doubt Perisphaeria afjinis Burm.; the first of 

 these is certainly not congeneric with C. gibbicollis Stal and a new genus must be 

 created for its reception; the type is in Brunner's collection and has been well 

 described so that it is easily recognisable, the other two species are of uncertain 

 systematic position. Stenopilema Sauss. of course sinks as a synonym of Cyrtotria 

 Stäl. It may be noted here that Perisphaeria linearis Walk, is synonymous with 

 Cyrtotria gibbicollis Stäl.
