We are satisfied, from the examination of the large series of 

 Guianan roaches before us and study of the original description 

 and figure, that DeGeer's rufa is correctly applicable to the 

 present form. It is also evident that rufescens of Beauvois is an 

 absolute synonym, material from San Domingo being at hand, 

 and the same is true of Walker's terminalis from Jamaica, from 

 which island we have a considerable series. This latter name 

 has already been correctly synonymized under rufescens by 

 Kirby;i2 that author, however, confused with the present, the 

 species capitata and hlattoides of Saussure, which species are 

 widely distinct members of different genera. Burmeister's 

 fumata is based on so inadequate a description that, without 

 examination of the type, the name can not be satisfactorily lo- 

 cated, though it is very possibly a synonym of rufa. Saussure
