This species seems to be widely distributed in Europe and on the 

 North American continent. In America, however, there is another 

 similar species (see sensoriata Mason) which, no doubt, has often been 

 confused with rubi. In many of the references in hterature it is 

 impossible to tell to which one the writer referred. Gillette had this 

 new species when he wrote: "A very similar species taken by Mr. 

 Bragg at Lawrence, Kans., differs by having cornicles decidedly 

 shorter and having joint 4 of the antenna in the alate viviparae well 

 set with sensoria. " Dr. C. P. Gillette kindly lent me this slide for 

 examination. Still another species which might be confused with 

 rubi Kaltenbach is described in this paper as reticulata, new species. 



The typical ruhi Kaltenbach, as fixed by Gillette, Van der Goot, 

 and Mordvilko and which is accepted here, has sensoria only on 

 segment III, while sensoriata Mason has them also on IV and V. 

 Gillette says that specimens from England examined by him are a 

 little smaller but agree in other respects with American specimens. 



The species described by Swain in 1919 is not rubi Kaltenbach. 

 He described specimens received from Gillette. I have had the 

 privilege of examing these same slides, kindly lent by Ferris, and they
